Hi Stasi, My little water pump has a pretty cheap pressure relief valve on it that I set for above 100 lbs PSI, and I have never tripped it but I have had the pressure around 140PSI. The tubing is really strong stainless thick wall tubing, called duplex stainless. I am not sure what pressure it can handle, but at least several hundred lbs. for sure. And if it ever did explode, it would not be too big of an explosion because the total water capacity of the steam generator is around 1 ounce of liquid...a little more when adding all the piping, but still a very small amount. I like your idea of making a pressure hammer! My long term plan is to run a generator and make electricity. Thanks for watching and commenting!

You may have damaged the seal when you were twisting with the pipe wrench. Or it may have been your problem that at a certain pressure it leaked? I think the "Junk" you found under the reservoir check valve may have stopped it from seating properly. At low pressures it can seal enough (or maybe leak slowly enough) to overcome the pressure on the main cylinder check valve and raise the jack. But once it reaches a certain point, the pressure on the main cylinder check valve is sufficient that the "junk" under the reservoir check valve prevents it from sealing sufficiently. All the fluid being pumped then returns back to the reservoir instead. The fact that the cylinder would hold that reduced pressure would indicate the main cylinder check valve functioned properly (and perhaps the bottom seal, as if that had failed I would be surprised if the jack worked at all.)
@oldtownvids4 ай бұрын
Thanks for your comment! The interior pipe which is the cylinder has pipe threads into the base and needs to tighten against the provided gasket to create the internal, high pressure seal. The top nut on the jack just holds the outside skin, which doubles as the outer reservoir cover, against another seal. The high pressure seal was damaged as can be seen in the video...me loosening the cylinder didn't cause that damage as it was already done. You are correct that it was damaged from tightening it, but that happened at the factory. I did a later video where I took out the seal I made and replaced it with a lead seal. That completely stopped the leakage and I wish they would have used a better seal to begin with. Still, glad to have it back working!

Hi my 50 tons jack is heavy to pump is it broken or its natural im the second owner
@oldtownvids9 ай бұрын
Hi Patrick, I'll try to answer your question. If the jack works, then that is a good thing. If you pump it but it does not lift, it needs looked at. If it is really hard to pump, then you might have junk in the ports or a damaged pump cylinder o-ring (or someone replaced the o-ring with a bigger one, trying to fix it). You can check these by taking the pump cylinder off, and you can check the o-ring. Maybe it was replaced with a bigger o-ring, making it hard to pump. If you set the jack on its side, so the pump is facing up, then you can take the pump off without losing oil. I hope this helps!

I haven't used the jack too much since installing the lead o-ring, but I have it on my bench and I am keeping it pressurized (a piece of wood being compressed) and weekly (or more) I check it to see if it has lost pressure. So far, it is holding tight!
@waterloocreek5659 Жыл бұрын
Quite interesting. I have a 100 ton bottle jack similar to yours but quite a bit bigger (76 kgs). My jack is squealing and not holding pressure. I’ve had my jack apart a few times. Interestingly the resivour had welding splatter that was affecting the ball bearings and stopping them from sealing properly. I use my jack to press coins and have pressed over 4000. The jack is now playing up again and I think the tap has scored the ball bearing and in turn damaged the ball seat. I’ve ordered a few new ball bearings and will braise a rod on one and then use valve grinding past to re polish the ball seat. Hopefully that will if nothing else rule that out. While I have the jack disassemble I’ll blow out all ports with compressed air. I’ll also check the seal you identified in your video. It’s a bit frustrating as for such a large jack the problem will likely be gunk under a ball bearing or a seal. Thanks again for your video.

That's interesting. I use my jack for a number of things, but it needed to be perfect to press copper sheets into some metal carvings, That is when it blew out. Note I put out a new video where I built a lead seal for the area between the cylinder and base...my formagasket silicone did not last. Weird that you had welding splatter in the reservoir. But it sounds like you are getting it done right by making sure the seats are perfect. I did note when I did the latest video I also had a lot of junk in the oil, so I filtered it out and cleaned where I could reach. Thanks for your comment!

@waterloocreek5659 Жыл бұрын
The outside reservoir/shell on my jack has a fully welded seam on the outside but it only has three tack welds on the inside. The welding spatter was never cleaned off. When I disassembled the jack the first time I could wipe the spatter off with my finger. I took emery paper and removed all the spatter and thoroughly cleaned the jack including all ports with balls removed. It should have been clean but it only needs one small piece of debris to disturb a ball from seating. I’ll try reseating the ball behind the tap and if that’s not the solution I’ll look closely at the gasket and if needed I’ll try your fix. It’s just amazing, the jack is 76kg and cost $600. Incredible that 5 tiny ball bearings and a couple of seal can cause such problems. In reality bottle jack regardless of size are so simple. My jack has 2 pumps. Some days I think Enerpac is the way forward but a 100 ton cylinder costs $3000 and up depending on model here in Australia. The Enerpac pump costs another $1700. I press Christian coins and give them away. If your interested you might like to check out Waterloo Creek on KZread. I made the video a few years ago now and there have been some improvements in the pressing process and much quicker. Anyway, thanks for your video and for sharing your experience.

I looked at your video (and subscribed!) and your jack is the bigger brother to mine.

Вы не правы. Если между основанием и цилиндром нет уплотнительного кольца, домкрат не будет удерживать давление. Этот домкрат теперь отлично работает из-за свинцового уплотнительного кольца. Не все резьбы идеально сцепляются, поэтому для идеального уплотнения используются уплотнительные кольца и прокладки. Шаровые краны не были проблемой. Вы можете видеть, что домкрат теперь держит давление на видео, и он застыл в течение нескольких дней под давлением и не вышел из строя после того, как ведущее уплотнительное кольцо было на месте. In English... You are incorrect. If there is no O-ring between the base and the cylinder, the jack will not hold pressure. This jack is now working perfectly because of the lead O-ring. Not all threads interlock perfectly so O rings and gaskets are used to make a perfect seal. The ball valves were not the problem. You can see that the jack now holds pressure in the video, and it set for several days under pressure and did not fail once the lead O ring was in place.

No degassing of the metal at all?? Unless it was all off camera? How you even made a whole part at 750F metal pouring temps blows me mind. Then poured the whole part one end with one vent at other lol Whole video was crazy! Not knocking it it just surprised me you ended up with a part as good as it turned out. Normally I'm pouring parts about 1300F in Oil Casting sand or plaster molds anyplace from 1 pound to 13 pounds at a pop. have like 10 vent holes and 10 or 12 gas escape holes poured from center of the molds. Never had missing parts in a mold or air bubble explosions like some seem to have for w/e reason.

1.My little temp gadget is in Celsus, 750C =1382F. 2.You never have to degas aluminum for a perfect pour...just don't boil it. 3.Skimming is always enough if your metal is clean. 4. Fluxing is sometimes needed but usually not understood and usually overused. 5. Venting was achieved by proper form design...don't leave any cavities that can't vent as the pour proceeds, so my forms vented without sprues. 6. I started this experiment on camera, so everyone could see the good and bad just like I did, and I totally expected failures along the way. Before moving on from this project, I did get both forms to make perfect parts, but ideally, this type of form is best suited to being machine pumped rather than hand poured, as the original pieces that I copied were made. The 2 things I see other casters typically do are using too much oil in their sand and heating the metal too high...above the boiling point. Both of these things will ruin a casting. Of course, venting is absolutely necessary to get right too. So, do I forgive you for your remarks? Sure. I'm glad to see other people casting! We need to keep this knowledge alive. My latest casting has moved on to brass, and my foundry has been modified to perform chemical assays, but as of August 2019, my channel has been shadow banned so I have lost the desire to post videos to it.

About the split pipe I use for extra/ billets, I thought I would have to do something to the surface so aluminum wouldn't stick, but I have never had any aluminum stick to any portion of it. The relatively dirty surface is likely a part of that but I think that maybe the expansion the pipe goes through might also keep aluminum from getting the opportunity to get really attached.

@oldtownvids3 жыл бұрын
I appreciate your comments, but a few things to consider: 1. If the push to open does not open the drawer at least 3 or 4 inches, you still have to have something to grab to open further because the clearances are too tight for fingers to get around. You could grab the corner, but giving the customer a grab area is more egronomic. 2. If the opener does move the drawer more than 3 or 4 inches, then you have created a tripping hazard. Not something a customer wants. 3. The tape I used is backed by VHB tape....not heat activated. Properly finished, the poly aids in permanently keeping the tape applied. Won't be coming off...ever. 4. I really like your idea of using a sticky roller to de fuzz a foam brush. Good idea! Thanks for watching and commenting.

And if it ever did explode, it would not be too big of an explosion because the total water capacity of the steam generator is around 1 ounce of liquid...a little more when adding all the piping, but still a very small amount. I like your idea of making a pressure hammer! My long term plan is to run a generator and make electricity. Thanks for watching and commenting!
You may have damaged the seal when you were twisting with the pipe wrench. Or it may have been your problem that at a certain pressure it leaked? I think the "Junk" you found under the reservoir check valve may have stopped it from seating properly. At low pressures it can seal enough (or maybe leak slowly enough) to overcome the pressure on the main cylinder check valve and raise the jack. But once it reaches a certain point, the pressure on the main cylinder check valve is sufficient that the "junk" under the reservoir check valve prevents it from sealing sufficiently. All the fluid being pumped then returns back to the reservoir instead. The fact that the cylinder would hold that reduced pressure would indicate the main cylinder check valve functioned properly (and perhaps the bottom seal, as if that had failed I would be surprised if the jack worked at all.)
Thanks for your comment! The interior pipe which is the cylinder has pipe threads into the base and needs to tighten against the provided gasket to create the internal, high pressure seal. The top nut on the jack just holds the outside skin, which doubles as the outer reservoir cover, against another seal. The high pressure seal was damaged as can be seen in the video...me loosening the cylinder didn't cause that damage as it was already done. You are correct that it was damaged from tightening it, but that happened at the factory. I did a later video where I took out the seal I made and replaced it with a lead seal. That completely stopped the leakage and I wish they would have used a better seal to begin with. Still, glad to have it back working!
While I'm only here for your "shop class" type videos, not tinkering stuff like this.. I'm surprised this channel doesn't have more subs. Old man vids are the best. I learned half of my known trades from old farts on KZread.
That's pretty cool! It does make sense though. The most expert folks usually got that way from lots of time doing their avocation. I do check other peoples channels when I'm on a new project too. Thanks about the subs. In 2019, youtube throttled my channel from over 10K views a day to under 100 views a day...they throttled a lot of political channels and apparently didn't like me even though I was not political. So my channel never recovered, and I believe it is still throttled by youtube. Glad you found my channel and thanks for your comment!
@@oldtownvids the eyes of our tech overlords are everywhere. I guess they consider anyone from the boomer era a threat to our “democracy” 🤣
@@oldtownvids while I haven’t dealt with it on KZread, I used to run a political channel on Instagram that was shadow banned into oblivion until I finally gave up trying. People don’t seem to understand the level of control these elites have over our lives.
@@oldtownvids crazy, I gave you a genuine, long response about the issue with political sh@d0w-b@nn!ng and my comment got removed. Just further proof that our tech overlords are always watching.

I hate the thought of it but you may be right. Our freedom is at huge risk and the people who claim they are fighting racism are actually the useful idiots of the left and they are true racists. However, they haven't won yet. I see you had a similar banning...but keep in mind they do that because they cannot compete! They can only cheat, and everyone not on the left wants freedom, so we are not going away and not giving in,. By the way, I have an even smaller channel, yes it is throttled too, but I say what I think there anyway and it is called Back Roads Of Colorado. Might want to check it out. Thanks for your comments! @backroadsofcolorado

Hi my 50 tons jack is heavy to pump is it broken or its natural im the second owner
Hi Patrick, I'll try to answer your question. If the jack works, then that is a good thing. If you pump it but it does not lift, it needs looked at. If it is really hard to pump, then you might have junk in the ports or a damaged pump cylinder o-ring (or someone replaced the o-ring with a bigger one, trying to fix it). You can check these by taking the pump cylinder off, and you can check the o-ring. Maybe it was replaced with a bigger o-ring, making it hard to pump. If you set the jack on its side, so the pump is facing up, then you can take the pump off without losing oil. I hope this helps!
Very nice.
Thanks! This has become an interesting and fun project. Now I need to get back to the steam generator. Thanks for watching.
cool! nice example of permanent casting using steel mold, although its for aluminum. do you know what mold material other than sand casting would be used to make steel copies?
Thanks! For steel, sand casting is pretty common but there are other types of casting material that will harden using gas to start a reaction. I don't know what the material is called, but you might search 'hardening casting media' and similar phrases and you can probably find it Hope that helps!
Thanks for suggesting your updated video on repairing your jack. Is it still holding up okay? How many times have you used it since the repair?
I haven't used the jack too much since installing the lead o-ring, but I have it on my bench and I am keeping it pressurized (a piece of wood being compressed) and weekly (or more) I check it to see if it has lost pressure. So far, it is holding tight!
Quite interesting. I have a 100 ton bottle jack similar to yours but quite a bit bigger (76 kgs). My jack is squealing and not holding pressure. I’ve had my jack apart a few times. Interestingly the resivour had welding splatter that was affecting the ball bearings and stopping them from sealing properly. I use my jack to press coins and have pressed over 4000. The jack is now playing up again and I think the tap has scored the ball bearing and in turn damaged the ball seat. I’ve ordered a few new ball bearings and will braise a rod on one and then use valve grinding past to re polish the ball seat. Hopefully that will if nothing else rule that out. While I have the jack disassemble I’ll blow out all ports with compressed air. I’ll also check the seal you identified in your video. It’s a bit frustrating as for such a large jack the problem will likely be gunk under a ball bearing or a seal. Thanks again for your video.
That's interesting. I use my jack for a number of things, but it needed to be perfect to press copper sheets into some metal carvings, That is when it blew out. Note I put out a new video where I built a lead seal for the area between the cylinder and base...my formagasket silicone did not last. Weird that you had welding splatter in the reservoir. But it sounds like you are getting it done right by making sure the seats are perfect. I did note when I did the latest video I also had a lot of junk in the oil, so I filtered it out and cleaned where I could reach. Thanks for your comment!
Hmmm…. You mentioned Chinese jacks. Seems most things are Chinese today. The outside shell/reservoir is full
The outside reservoir/shell on my jack has a fully welded seam on the outside but it only has three tack welds on the inside. The welding spatter was never cleaned off. When I disassembled the jack the first time I could wipe the spatter off with my finger. I took emery paper and removed all the spatter and thoroughly cleaned the jack including all ports with balls removed. It should have been clean but it only needs one small piece of debris to disturb a ball from seating. I’ll try reseating the ball behind the tap and if that’s not the solution I’ll look closely at the gasket and if needed I’ll try your fix. It’s just amazing, the jack is 76kg and cost $600. Incredible that 5 tiny ball bearings and a couple of seal can cause such problems. In reality bottle jack regardless of size are so simple. My jack has 2 pumps. Some days I think Enerpac is the way forward but a 100 ton cylinder costs $3000 and up depending on model here in Australia. The Enerpac pump costs another $1700. I press Christian coins and give them away. If your interested you might like to check out Waterloo Creek on KZread. I made the video a few years ago now and there have been some improvements in the pressing process and much quicker. Anyway, thanks for your video and for sharing your experience.
Yes the enerpac equipment is really high priced. I am with you...a simple bottle jack is best if you don't need something that is too portable. I looked at your video (and subscribed!) and your jack is the bigger brother to mine. As far as the welding spatter goes, I bet mine was put together same as yours, and mine could have had spatter in it too. Makes sense now because mig welding does shoot splatter everywhere. I used to have my copper pressing videos posted but since youtube shadow banned my channel, I have taken several of my videos down but I will add a picture of the finished plates on my main comments section. Great to see your work too! You probably noticed I built my pressing frame..it does look rough but it has served me very well. Yours is much nicer though!
Your video was the only video that went it detail past the obvious. There are lots of those videos out there. Thanks for your feedback. I basically stopped posting a couple of years ago to due to feeling the algorithm for my videos changed. Where would I find the pictures of your copper pressing.
Хорошая идея, но к сожалению бесполезная, даже если не будет кольца домкрат будет работать, поэтому, что масло через резьбовое соединение все равно не пройдет и если пройдёт то не критично, проблема в этих домкратах шарики и их уплотнения...
Вы не правы. Если между основанием и цилиндром нет уплотнительного кольца, домкрат не будет удерживать давление. Этот домкрат теперь отлично работает из-за свинцового уплотнительного кольца. Не все резьбы идеально сцепляются, поэтому для идеального уплотнения используются уплотнительные кольца и прокладки. Шаровые краны не были проблемой. Вы можете видеть, что домкрат теперь держит давление на видео, и он застыл в течение нескольких дней под давлением и не вышел из строя после того, как ведущее уплотнительное кольцо было на месте. In English... You are incorrect. If there is no O-ring between the base and the cylinder, the jack will not hold pressure. This jack is now working perfectly because of the lead O-ring. Not all threads interlock perfectly so O rings and gaskets are used to make a perfect seal. The ball valves were not the problem. You can see that the jack now holds pressure in the video, and it set for several days under pressure and did not fail once the lead O ring was in place.

Thank you for the solder ring seal idea. I'm rebuilding an old f-250 jack. I think that it had some type of loc-tite at the base of mine. Going to make a solder ring just as soon as i finish watching the video.
Hi Brian, I hope it works out as well for you as it did for me. Thanks for watching! Note I'm answering from my other channel, back roads of colorado.
Nice!!!!
Thanks! That video is getting old, but the foundry is still holding up well.
I have 2 of these 50 ton jacks, they still work. I got them for jacking up the house foundation. They did a great job.
I had first bought 2 Big Red 20 ton jacks from HD. They were not working right out of the box. I took them right back to the store. They bypassed and could not lift anything. They were junk like brand new junk. The instructions made a lot of stupid worthless remarks about bleeding them when they cant lift. Almost like the company expected them to never work as they should, and were blaming the customer for not knowing how to maintain the jack.
I'm with you there! As for my 50 ton jack, I really think that when they assembled it, the o-ring got caught in the threading between the cylinder and base, and hard use caused the ring to leak. I wonder if your 2 50 ton jacks were assembled better (o-ring not being caught up in the threads like mine)? I'm glad to hear your 50 ton jacks are working! Finally my jack is solid...just a bit of a detour to get it working, having to make my own o-ring out of lead. Thanks for watching.
@@oldtownvids In the video you used silicon gasket maker, did that fail? I suppose you might be able to use a length of round solid solder off a roll
Yes I used 1/8" diameter solder, soldered as a ring. I put up a video about that a few weeks ago...kzread.info/dash/bejne/lH6bzbpuppy6pLA.html The gasket maker didn't hold up after a couple of months, so I decided to permanently repair it with the lead o-ring and it worked very well.
Nice info, subscribed to this as well as your backroads channel. Couldn’t find this channel until I searched the whole title as you suggested. Thanks.
Thanks Tim! Yes, youtube basically shut this channel down in August 2019: I watched it go from getting over 10k views/day to under 100...all in one day, and at the time when youtube was shutting down several conservative channels. So it's not easy to find, even I have a tough time searching for it unless I link it to a one of the named videos.
Totally lost me in this video lol........... You had the aluminum at 750F? Way to cold........ 1300 to 1400F ideal pouring temps for aluminum. Your not using any flux materials??? No degassing of the metal at all?? Unless it was all off camera? How you even made a whole part at 750F metal pouring temps blows me mind. Then poured the whole part one end with one vent at other lol Whole video was crazy! Not knocking it it just surprised me you ended up with a part as good as it turned out. Normally I'm pouring parts about 1300F in Oil Casting sand or plaster molds anyplace from 1 pound to 13 pounds at a pop. have like 10 vent holes and 10 or 12 gas escape holes poured from center of the molds. Never had missing parts in a mold or air bubble explosions like some seem to have for w/e reason.
1.My little temp gadget is in Celsus, 750C =1382F. 2.You never have to degas aluminum for a perfect pour...just don't boil it. 3.Skimming is always enough if your metal is clean. 4. Fluxing is sometimes needed but usually not understood and usually overused. 5. Venting was achieved by proper form design...don't leave any cavities that can't vent as the pour proceeds, so my forms vented without sprues. 6. I started this experiment on camera, so everyone could see the good and bad just like I did, and I totally expected failures along the way. Before moving on from this project, I did get both forms to make perfect parts, but ideally, this type of form is best suited to being machine pumped rather than hand poured, as the original pieces that I copied were made. The 2 things I see other casters typically do are using too much oil in their sand and heating the metal too high...above the boiling point. Both of these things will ruin a casting. Of course, venting is absolutely necessary to get right too. So, do I forgive you for your remarks? Sure. I'm glad to see other people casting! We need to keep this knowledge alive. My latest casting has moved on to brass, and my foundry has been modified to perform chemical assays, but as of August 2019, my channel has been shadow banned so I have lost the desire to post videos to it. Thanks for watching!
This is great. Thanks for sharing your design and process.
Thanks! A fun project. Thanks for watching!
How much about 50 tons bottled jack?
I think it was from amazon.com, and was under $100.00 I hope I answered your question! Thanks for watching.
Saan nkakabili Ng oring Ng 50 tons bottled jack?
Have you received any copyright strikes? Nice playlist ✊
Thanks, but it isn't something I try to include in my videos because of the way the copyright laws are interpreted presently. So, if I accidently record music, I have to edit out most of the recording to avoid issues. It makes recording videos in my shop a bit less fun because I have to try to keep the music out of them...and I am usually working on musical instruments...some irony there, I suppose. Thanks for watching!
Preheating evaporates any moisture to avoid motlen metal exploding on contact with the mold.
I looked at every one of the videos an yours has been the only one that has been any help. Thanks a lot
Thanks! I had the same result when the jack broke...no useful videos about it...so I decided to make my video. I do think that a lead o-ring is the best solution and I may make another video about that. Thanks for watching!
I love watching your video shoots.❤️❤️
Thanks for watching! You might notice that the video quality may improve from now on, as long as the new gimbal behaves!
Amazing Job!! Congratulations!!!!
Thanks for watching!
Ok
I do the same thing but I use empty coke cans with the tops open so I can pour into them. I just set them in sand up to the top edge and pour. The castings already have a nice smooth skin before they even get poured! I use the castings on my lathe making stuff. Since most of the parts I make are bike parts , they pretty much all fit within the size of the can. Works very well for me. By the way if you're not sooting the inside of that pipe form try it, it makes getting the aluminum billet out much easier.
That's a great idea! And, if you are watching your temp, which I bet you do, you can get nice high quality billets....and as you said, a good size for making bike parts. About the split pipe I use for extra/ billets, I thought I would have to do something to the surface so aluminum wouldn't stick, but I have never had any aluminum stick to any portion of it. The relatively dirty surface is likely a part of that but I think that maybe the expansion the pipe goes through might also keep aluminum from getting the opportunity to get really attached. Thanks for watching!
Nice work -keep them coming 👍 n sub
Thanks! Now that youtube has unthrottled me, I am back!
🤦
Tell me more about the ‘awl’ thread…
I also call connecting nuts banjo bolts!
Thanks again it really help me out a lot I sure do appreciate it
Glad I could help!
Thank you a lot you really have helped me to understand the Jack better I’ve had the same problem thank you so much
You're welcome! I am finding that o-rings don't last long in this jack, so I intend to build and install a lead ring. I'll video that too, because I think it will be permanent!
good 👍
Thanks!
Thank you for the good information on the other side of the world
Thanks for watching!
the result was pretty good ! ussually the mold should be preheated so as to keep the moltened aluminum sliding down with no resistance. since it was held outdoor with low temperature it also contributed to fast hardening of the metal.
Yes I think keeping the forms hot would make the pouring go much better...in my steel forms, It is worth building a heater for these.
Buddy i just watched your vid and to me that setup is about as useless as tits on a bore hog. Way over complicated but if it works for you more power to you. lol have a good day.
I like to let all the people who watch my little channel see all comments, even those that disagree with my content. There is one thing that I overbuilt, and that is the lock bolt...it isn't needed. And, there is a lot of extra stuff that isn't absolutely necessary, but makes the pouring go really easy. So, for the folks who don't pour too much, less is usually better. For those who pour a lot, and by themselves, and melt heavier material (that crucible can hold 60 lbs of brass), then the extra stuff becomes a lot less in your words, useless. And the extra work to make a cylinder of metal rather than making little discs gives me the ability to make high quality large cylinders that are pretty useful (and save a decent amount of money) for machining bigger parts. I am not trying to convince you...your opinion is yours, but you give me a good platform to describe the extra parts for people who might wonder why I made them. So, LOL have a good day!
System of a down
Yes! And I wish I didn't have to censor my music! I don't think the copyright laws actually work in the favor of the musicians when they censor little snippets of songs a viewer might not have heard. I purchase music after hearing parts of it on youtube, in the rare instances it exists. If just a part of a song is in the background, it seems like more of an advertisement than a copyright infringement. But the music industry is too greedy to understand, so I think.
I just binge watched all 6 video's, very interesting to watch you work through the trial and error stages. I can't imagine how much time you spent on the steel moulds, you are a very clever guy to work out how to make those from scratch. Looking forward to your other videos. Well done that man !
Thanks!
Good idea for the mold. Thanks for showing. Might adapt the design for my own castings.
If I watch my temp when I pour (which I always do nowadays) I can make really high quality castings from that cylindrical mold. Useful!
videos of the Samurai!
I know! I have a 1.9 TDI on a stand, ready to install in it. Just need time! But it would make a good video. Thanks!
Opps, I meant 1.9 TD, not tdi!
Very nice video on this subject, the biggest problem of all when repairing this jacks is where to find the gaskets and seals to do the job. In particular if these are made in China that have the market flooded with and are about the only ones you can buy nowadays. The few U,S brands available are out of sight price ways. Around five to six times more expensive than the Chinese counterparts.Thanks for the video, very interesting and educative.
True! And, this jack failed about a month later due to the composition of the replacement o-ring. I am thinking of making a lead gasket to replace it.
like the Idea but cant give up the EZ levels
I'm with you there!
To fast over the mould making and too much talking slowing down over the other parts :-(
Agree. Hard to decide what to use in footage, especially shaky footage like I seem to get too much of! Thanks!
The sides are way to thick. Think in terms of 0.08" would be a good starting point and going down to 0.07".
Keep in mind that the sides and back should be rigid. The top is the only part that should vibrate. If you begin with thicker material, you will have more for shaping and a much stronger shell as long as it is braced perpendicularly to its grain so it won't develop cracks. Does make for a weightier guitar, but for me and the folks that I build for, that is way down on the list... tone and presence are king and stiff sides and back are really important for acoustic quality. Thanks!
@@oldtownvids Oh Nay Nay, The worst guitar I ever built had eighth inch sides and back and it sounded horribly muffled. I'm sure we could have a disagreeable argument over the subject but just bear in mind that you're wrong.
@@jimgeorge6220 Alright Jim. Have a great day!
How many years you own this Jack and how many times a day or month would you say you used it? Thanks
I had it for about 10 years but only use it rarely. Probably not more than 20 times in all 10 years. It is not very good quality, but it was very cheap, so really not a bad deal. But I would get a better jack if I have to use it more often. Thanks for watching.
This is amazing, does the length of the tubes below the keys effect the pitch at all or is it just tuned by the length of the keys?
Thanks! Both the bars and the tubes have to be the right length. The bars set the frequency, but the tubes amplify the frequency. But only when they are the right length. Thanks for watching!
Very helpful video
Thanks!
Next time use push to open drawer rails, then you don’t need a hole or a handle. You just push it with your foot and it pops open. Also, I seriously hope you ironed that edge banding, otherwise it’s just going to fall off later. You have to melt the glue to bond it to the wood. One more thing, apply polycrylic with a foam roller that you’ve cleaned by running it along some tape to get off any dust or factory fuzz. It’ll give you a much better finish.
I appreciate your comments, but a few things to consider: 1. If the push to open does not open the drawer at least 3 or 4 inches, you still have to have something to grab to open further because the clearances are too tight for fingers to get around. You could grab the corner, but giving the customer a grab area is more egronomic. 2. If the opener does move the drawer more than 3 or 4 inches, then you have created a tripping hazard. Not something a customer wants. 3. The tape I used is backed by VHB tape....not heat activated. Properly finished, the poly aids in permanently keeping the tape applied. Won't be coming off...ever. 4. I really like your idea of using a sticky roller to de fuzz a foam brush. Good idea! Thanks for watching and commenting.
