Geir, Thank you for your comment. I am glad if anything I have put out there has been of use to you. I have thought of doing a video or two along the lines that you have suggested and indeed I have one planed for sure (I hope 😊) that I will shoot in the next week or two. Generally though there is the problem that most ideas that come to mind require at least some physicality and I am limited to about 30 quite uncomfortable minutes at best. The videos in the moulding box series were done with gritted teeth a little bit at a time ( ah, the wonders of editing 😊) and much as I would like to get back to that series and finish it off I am not currently up to it either physically or mentally - I need to get some medical certainty one way or another - this not knowing for sure and worrying about it takes a heavy toll. Another problem is that ( I think) people much prefer seeing flame and molten metal and action etc rather than a dry talking head going on (boringly) about the finer points of making a good casting, But we will see as then planned video will feature one of my castings now all machined up and presented as an example of what is possible if - unlike many on YT - care is taken all during the process. I will vent a little spleen 🤬at some of those (unnamed) who do not seem to care at all but still put out casting videos... Regards, Martin

They carry a large range of foundry stuff, fluxes mould coats dye coats etc. You will have to buy in whatever size they sell (the exothermic is in 25 Kg bags as is the coverall 11 flux I get from them. I get my aluminium ingots from Haynes Metals also in Sydney. Crucibles and refractories from Vesuvius same address as Foseco. Be aware that some small suppliers (who will sell small quantities) seem to want to solve the national debt with every sale that "green sand" mob want $7.50 for 1/2 Kg of calcium carbonate parting agent (it's what I use) But I got mine at less than $3.00 per Kg from (I think ) Consolidated Minerals (25 Kg bag). Try to get to know other local hobby foundry types buy in reasonable qtys and split. NOTE some things can NOT be sent via post exothermic is one of these - don't try it nitrate sniffers will catch you out. Talk to local professional (small) foundries best contacted mid morning ask them where they get there stuff from and if in exchange for good old fashioned folding stuff (beer money) they will sell small amounts to you I know people who get their metal this way paying a premium price of $5.00 per Kg.

cobra, Well done! Foundry work isn't easy but its a lot easier when done as close to right as manageable. I try to show what I have found to be the right methods. I am sorry that I have not been able to finish the moulding box series as yet. Health issues (still ongoing) forced me to suspend video making mid way through the series, and most unfortunately just as I was about to demonstrate the hardest bit - fitting the pins. I hope to get back to it but it may be a month or two yet! My initial trials drilling the pin holes showed a problem in that the drill tended to run down the slope on the pin ears, meaning that the holes were inaccurately positioned and not vertical. This is a problem with drill presses - they are not very rigid and also drills can flex a lot. Use of a mill and bolting things in place would be a big help and if one has a mill the only smart thing to do. However, I had said that I would show how to do it without using a mill because not everybody has a mill. I have developed a method and now just have to get well enough to demonstrate this and finish the video series off. I always figured that anyone who made any of these boxes would never regret the effort - they are just so much better than wooden ones. Over the years I have made about 40 such boxes (various styles !😊)and I have been glad of them ever since.....Martin

Without this - i.e. with two holes - the boxes would simply not be usable. The modularity / versatility has worked on older (and cruder) boxes of a similar design.

Nice series, I finally watch, skimmed, through all of them. Not sure if I'll even post this comment, but if you're reading it, I did. Importantly, this is not a criticism. Just offering a different idea. I have 4 cast aluminum flask sizes. For small parts I use a 5"×7" cope and drag, each is 2 1/4" high. This flask is cast in one piece, using a core for the on inside. The other 3 are, 7×8, 7×10, and 9×10. I have ribs on the outside and 2 grooves inside. Except for the 5×7 flask I made 2" high upsets that will work for all the flasks. In total 4 patterns for the flasks and 3 for the upsets. For specific needs I make wood flasks but I made 2 identical patterns for the pins. Now do I post the comment or not, oh what the heck, post it.

Roscoe, I am glad that you posted and thank you for it. I too have cast small boxes - well one small box - I made it about 45 plus years ago and it is very rough but I did use it from time to time, it is much the same size as your cast in one piece. I have found that a smooth i.e. ribless outside of the box is at times a handy feature as it allows me to guide the box with for example a heavy piece of very thick bar standing on its end on the bench - I have used of such guides around a box for a very high lift and for a close of a double height cope over a high core. The ribs are on the inside form maximum sand holding - I have found that things like groves do no always cut it and drops can occur (with my sand anyway.) My metal box sizes are 6*8, 8*10, 10*12 and 8*12 I have 11 each of the first three and two of the last, heights are 3.5 inch except fort the 6*8 which are a little lower. I have some older cast sides that were not much of a success - used them in this video series though, they were all 4 inches high (Too high) and used the diagonal corners but were ribbed both inside and out - but I pinned them badly. I have perhaps 70 or so individual cast sides plus another 30 or so just 2.5 inches high - never used these much!

Jim, Casting any pure metal can be a bit of a problem. They solidify with pronounced central pipe shrinkage and this can lead to large cavities going right down through any feeder and into the casting. Also such metals are prone to develop shrinkage -again large holes - at any hot spots, gate / casting junctions being typical. But what exactly is the problem that you are having, I could perhaps be a bit more specific if I knew exactly what was going wrong.... Martin

@@olfoundryman8418 Thank you so much for getting back to me. I hope all is well with you. Your videos have really helped me move along with my own casting. My Dad was right: Always learn from the man who makes his living doing what you want to learn. Anyway-my problem is with the metal freezing before it has finished filling the mold cavity. The pieces I am trying to cast in copper are about 16 inches long and the bottom half is roughly 3/4 of an inch in diameter-no problem there. The fill runs directly into the bottom of the piece and flows to what will be the top of the piece. A little more than half way up the design splits into three pieces about 1/4 of an inch in diameter. In pouring at nearly 2500 F the metal gets about half way up those narrower pieces and freezes. When you look closely at the ends you can see that the outer surface in contact with the sand mold chilled and the core continued briefly before freezing as well. I had tried pouring from the center but pretty much the same thing happened. I am currently working on a refractory plaster mold-50/50 silica flour/hydrocal and plan to bake it and pour into the mold when the mold is at about 400 F. Also using a variation on your tipping mold for this. The variation is that the mold will be at about a 45 degree angle with the pouring basin cast into the mold at the base of the piece I am trying to cast. Again, thanks, and hope you are weathering the covid thing that has plagued us all. Jim

Jim, If I read your reply correctly you have a casting standing 16 inches high the bottom 8 inches of which are 3/4 of an inch in diameter the upper 8 inches of which are tree 1/4 inch diameter sections - sort of a three pronged fork . And you are running the metal to the bottom of the 3/4 inch section. The metal (pure copper) gets about 34 inches up the three 1/4 inch sections and runs out of puff and solidifies. You are pouring the metal at a rather hot 2500 Deg F. (Wow!) Do I have this about right? Pure copper is very fluid but I am not surprised that it is not making it any more than 4 inches up the 1/4 inch sections. These are a bit of an ask. Not surprised the same happened with center pouring as this divides the stream two ways and although the 1/4 bits will benefit from hotter metal the flow rate in them wil be lower - sort of a win and a loss giving you a draw! Considering how metal flows the shape of the 1/4 ends is as I would expect. Some suggestions: Make sure the top of the 1/4 inch sections are vented to the atmosphere. Assuming a sand mould oven dry the mould completely may take 4 hours at 150 to 200 deg c - support mould well while drying. Smoke the mould (whatever its made from) with an acetylene flame, this is said to increase flow distances by about 300% (yes 300%) NOTE, only acetylene works - LPG no good. Re refractory mix, not too sure about silica flour - too fine? The brew I have seen documented is 60% plaster of paris, 25% 50 mesh silica sand, 15% talc, water to a creamy consistency (whatever that means 😏) Drying /curing of these plaster based moulds is an exacting business and very necessary to success. Have a look at the Kerr web site in it they list the sort of bake out cure preheat cycles required including peak temp and mould temp when pouring. If you do not follow something like this your moulds will probably all crack and will give off steam when the copper is poured so ruining the casting. If going to a tilt cast start the mould at 20 degrees UP so the pouring basin is at the low end. In this way the metal wil fill the mould as a wave not as a thin stream. Have the 3/4 inch thick section nearest the pouring basin and have a feeder between the basin and the start of the 3/4 inch thick section. Adjust basin height and size so that when you have the right amount of metal in it the metal is just starting to enter the feeder start tilt the instant basin is full. Not an easy job you are trying to do here - good luck! If I have it wrong send drawing to olfoundryman@gmail.com.... Martin

The customer's first choice is copper but they have recently indicated that aluminum with a copper finish would make them happy if it gets the job done. Still, I would like to solve the problem.

JIm, I know luckygen quite well, he lives maybe 80 miles away from me and we have enjoyed quite a few cuppas and good conversation. The use of coal dust is unique to the cast iron industry. Under the influence of the heat of the metal the coal out gases and provides a reducing atmosphere in the mould this stops the formation of iron oxide on the metal surface. If it were to form this iron oxide can flux with the silica sand and cause a lot of sticky burn on. Also the gas produces pressure locally in the sand grains and this helps stop the metal penetrating between them. Thus the surface improves. BUT it has to be coal dust, charcoal or graphite will not do as they will not produce gas when heated. Lucky's recent experiment using wood was based on the fact that wood will also out gas when heated. He pointed out that it has to be dry wood as the water in wet would will create all sorts of problems. I think he also pointed out that it should be fine, preferably wood flour in fact. I have suggest to him that he could also try corn flour or even wheat flour as if wood flour works these should too. But I don't see the effect of these substances being of much help with your copper casting. Yes I would be most interested to see how it all turns out and what you do to get it to work - as I am sure you will. Hmm, "run away to join the circus" reminds me of a friendly pattern maker of my acquaintance who said that he was going to do his own casting but he wisely kept taking the medication and the idea went away ..😊..

After a few years of using bean cans to get the pressure, and getting very porous castings, I thought I would try a tapered sprue as you suggest. A couple of degrees tapering down to 8mm.

I will have a go at a set once I have resolved this problem.

@olfoundryman8418

3 жыл бұрын

Ian, Well, that is all a bit disappointing. The most obvious/likely cause is cold metal. Do you know what temp you poured at? How did you measure it? If you are one of those people who judge by eye (many people do) you need to be aware that on a bright day the metal will look cold but on a dull day it will look hot even though the temp on both days is the same. The apparent colour change from silver to red to pink to yellow is very marked near the pouring temps and even slight background light changes can fool you. I consider my thermocouple one of my more indispensable pieces of equipment, and I record the pouring temp of all my aluminium castings (I have a data sheet for every casting for future reference) If you do not have a thermocouple I strongly urge you to get one. However there are other possible causes, What was your metal source - mixed alloys and worse still a mix of cast and wrought aluminium can cause lots of trouble. Fine material (machining swarf, chips, turnings can be very bad as the resulting metal will contain lots of fluidity robbing oxide - I have seen aluminium produced from these materials so thick with oxide that it was like porridge and about as fluid.😱 Another problem is with the shape of the pouring basin I have seen people cut the basin with a spoon and this can make basin like half a sphere, this can interfere with the flow - keep the basin vertically sided. Even worse is the all to common problem of the ridge between the basin and the sprue being too high. This ridge should be NO MORE THAN 5 to 10 mm high from the bottom of the basin - thus if the basin is say, 40 mm deep there should be 30 to 35 mm of metal over the top of the ridge during the pour. People seem to get his the wrong way round and have just 5 to 10 mm of metal over the ridge - won't work like this! As a final point the junction of the sprue and ridge must be well radiused. If it isn't an air trap will occur where the radius should be and this will greatly restrict flow. Go and have a look at my basin and sprue video and see if your basin and sprue conformed to that. I the next video showing sprue calculations (a few weeks away yet) I will show an actual poured basin and sprue so you can compare that to what yours looks like. As a clue if the aluminium froze in the sprue it likely would have been very close to freezing in the ladle/crucible too. What did that look like at the time -were you able to pour the metal out of the crucible and into say, ingots or was it too pasty? As a matter of interest I have occasionally had a sprue partially blocked by sand effectively my 8 mm sprue was a 4 mm sprue - it did not freeze - casting took a long while to pour though😊 8 mm with 2 degrees per side should be OK, 1 degree per side - Eh perhaps not so much - I use 1.4 degrees per side but be aware that there is no universal taper - darn it 😰...Martin PS high sprues are supposed (huh, supposed) to help avoid porosity as allegedly (huh) the extra pressure makes it more difficult for porosity form and gas to come out of solution - well maybe!

@@olfoundryman8418 Hello. Thanks very much for not only taking the time to reply, but coming back with so much information. I do have a thermocouple. I stopped heating when the temperature read 730 degrees, but it may have been hotter than this as the temperature reading was still going up. The aluminium I use consists mainly of aluminium extrusions. Half of the material was metal that had been previously melted (old feeders and risers) but no cans or shavings. After the fail, I went on to pour half a dozen ingots into cake tins. Looking at the metal at the end of the sprue - the end looks rounded and 'fluffy' so I guess it did not hit a blockage. I did aim for the 10mm ridge as you have instructed, but measuring the metal left I can see the ridge is much higher at about 20mm so this may be the cause. It was cut with a spoon . I also see that I radiused the wrong side. I put a large radius basin-ridge, but ridge-sprue is quite tight. I will have another look at your basin and sprue video, and try again when the weather gets a bit cooler. Thanks again.

Ian, 730 deg C would be fine - only very thin work would have miss run at this temperature and a round 8 mm sprue definitely should not have. I am not much in favour of using extrusion material. Basically people a lot smarter than the two of us developed alloys for specific uses and end products. Extrusion alloys are very different from casting alloys and whilst they will melt, turn to liquid, and can be cast the results are uncertain as to how well they will fill a mould and how use-able the casting will be. I would recommend sticking to a casting alloys - if you can afford it buy some decent 356 ingot - you will not know yourself! Alternatively get some alloy wheels but be careful not all of them are 356 (BMW wheels for example are not.) Many (but sadly not all) wheels have numbers on the back indicating the alloy used. One problem with small sprues is that they can block with sand very easily - I always look through the sprue to make sure there is no blockage. Can you send a photo of the end of that sprue to olfoundryman@gmail.com I would like to look at it and maybe make a guess at what the problem was. Sounds like your sprue/basin was a little off (just a little)😏 and that sure would not have helped but I am a bit surprised that it would cause the sprue itself to fail to run... Martin

Silicone, Aluminium picking up on files is a universal problem. Rubbish junk aluminium is usually worse. But even good quality aluminium like 356 ingot will do it too, but you can improve the situation by T5 heat treating your castings - if made in a heat treatable alloy of course. This will increase the hardness of the aluminium and thus it will be less likely to pick up on a file (or build up on a lathe tool or a drill). Some people put WD40 on the file and this can help but sometimes it just makes the file slip! The old standard trick was to rub the file with chalk (hard welders chalk preferably) this plus frequent cleaning with a file card will help quite a lot.... Martin

Admittedly 60ml truly is in the ant-league, but the convenience and ease is a thing to behold: turn it on and you've got a melt in a minute or two. Like the microwave meal of the casting world.

Neil, Ah, Ha! A fellow Aussie! Note that my one experience with cast iron was a failure and it was back in about 1967. The person you should be asking is Luckygen1001 - he lives in the Gippsland area, and has been doing iron for about 30 years. He has lots of videos and I suggest that you watch them. Cast iron is said to be Gods gift to the foundry man - mainly I think because it does not shrink (if you get the composition right) and because it is very fluid. I know that Lucky does use brake discs as feed stock so I guess they are a wise choice. He has spoken of old sewing machines as the best iron out there! Not all furnaces will get hot enough depending on how well built or not they are and not all have suitable refractories in them. Lucky has a video on furnace building for iron melting. It is very hot and very hard on crucibles, furnace linings and foundry men 😊. You cannot use Silicon carbide crucibles for although they last far longer with aluminium and bronze they have an upper temperature limit of about 1350 deg C and you really need better performance than that with iron - so you must use clay graphite crucibles. I don't think lucky uses any flux and if he does its probably just limestone. Note that fluxes of any sort with any melt shorten crucible life. He does use an addition of ferrosilicon and this is important in producing a usable grey iron without chill. Sadly my crucible contact has retired but depending on the size you need I may/might/perhaps/ possibly have one here that I could sell you.

I forgot to put in a comment! I like this. The only thing that I could maybe add is that if the corners are clamped together as a two piece unit under a squared up setting perhaps a squared piece of 18mm sheet and drilled as a unit with a hand drill you might end up with a little more square box. Not that this was all that much put in the first place.

Mark, The problem with just two sides at a time is that they have a draft angle on the top and bottom faces, this makes it difficult to sit the two sides together properly as they tend to try and sit flat on the draft angle. To avoid this I decided to put the 4 sides together at the same time and it does seem to work better this way. The squareness issue is because the 45 degree ends are not exactly 45 degrees. The patterns printed at 45 degrees (within the limits of our ability to measure) but there appears to be slight distortion during casting - probably the solidification contraction causes the 45 sides to "open their legs a little" - by measure and calculation it looks as though the 45 is only 44.5 to 44.8. I could of course set it all up under my CNC mill and turn it into a precision machined thing - exactly 45 corners and exactly square boxes but that is not the brief here, the job is to be - and will be - done without such luxuries as a milling machine. I am currently struggling with fitting the pins and what a battle royal that is turning out to be as I develop a suitable and easily copy-able technique. Current major difficulty is getting the fixed pins square to the box side - problems come from the fact that the pin holes have to be drilled through a sloped surface and the drill tends to run off also the amount of flex in a drill press is unbelievable! Still ever onward we strive.... Martin

i totally liked the concept of the modularity, but it somehow got me wondering if it is worth the additional effort at all. Usually you use 2-3 different kinds of boxes, and the amount of variation on the modular ones due to them being about the same height is so little, that i'd end up just using the next larger ones (in all dimensions) instead of fiddling with them. If i'd make some instead of using the professional steel ones or the improvised wood ones, i'd most likely cast them as one piece, or in the worst case two L-shaped pieces that are somewhat easier to mold. On the other hand the internal draft could be an inverted rib to catch the sand, one core insert per lock side... pretty easy to make them as one piece. But it's a nice project for beginners that don't have all the wood-equipment nor welding equipment but a 3d printer and a bit of time on their hands nonetheless. They look fabulous!

Rocketeri, I am sorry for the great delay in writing this reply - I am a bit overwhelmed and under capable at the moment and find it difficult (read, impossible) to keep up. Firstly, absolutely no offence taken! I appreciate all comments and particularly those that provoke thought - they keep me on my toes and keep me learning. You are quite right about the 2 to 3 different boxes. 50 % of my work is done in what I call my 8*10 inch box, 25% in my 6*8 inch, and 20% in my 10* 12 inch. The remaining 5% is spread across 40 or so wooden boxes of all shapes and sizes (the limit being a box that I can lift at least half of when rammed full of sand - it’s a limit forever getting smaller with age 😊. However, my work has been mainly productions of small runs. It is highly repetitive in nature, the same jobs keep coming up. I don’t see this as a situation that would apply to a hobbyist. Thinking back to my early days just about every job was different and often required a different box that I would have to go and make up. If reasonably possible I did just use the “next largest box” but there can be a significant problem with doing this. Take my 8*10 - it has an area of 80 square inches my “next largest box” 10*12 has an area of 120 square inch. That is a 50% increase for just an inch bigger all round - 50% more weight, 50% more sand to ram, 50% more sand to reprocess, 50% increase in effort and time, and of course 50% more sand to have in the first place. If using petrobond as a lot of hobbyists do that’s an expensive 50%. I have about 600Kg of sand in play at any given time with petrobond at $4.00 per Kg (local) that’s $2400.00 a lot of money. Hence I use a natural green sand. Even if our hobbyist has just 100 to 200 Kg to play with its still $400 to $800 worth and I would regard 100 Kg as an absolute minimum if more than a couple of castings are going to be made at any one time. Its not difficult to see why petrobond users scrabble to save every grain. BUT even with green sand it still has to be obtained/made/prepared and although a lot cheaper than petrobond in dollar terms its much the same in effort. So, to me the “next largest box” approach, while useful, has limitations. Personally, and while I know that many professionals do use them I would never use steel boxes - to damn heavy! I have tried casting a box in one piece and Luckygen1001 has done a bit of that. I did contemplate the “L” shaped idea too. However, our brief here was to produce a versatile box - really a collection of box sides that could be assembled in many, many ways to produce a plethora of box shapes, sizes, and configurations. A little job, bolt together 4 off 150 long sides for each of cope and drag, a very long job bolt together 2 off 150 and 4 (or more) off 300 (with intermediate wood spacers and some cross bolts. Etc., etc I am sure you get the idea. We are trying to cover as many eventualities as possible here without the need to make a quick roughie wooden box every time a different job comes up. This is what I used to do and I now have well over 70 boxes with about half of them wooden - in all shapes and sizes - being used for that 5% of the work. I have then stuffed everywhere, up in the rafters and clogging shelves. Of course, I do realize that to get this versatility it would be necessary to make at least 8 of each of the 4 side lengths plus any additional of the two middle sizes. That’s 48 castings - quite an ask and probably not many will do it (pity☹) Although note that I have done 1 run of 64 one of 84 and another of 188. After some thought based on experience, we figured that the 45 degree mitre corner was the only way to achieve the end result we were after and allow box side production with no milling machine or lathe. As a final comment I do realize that most likely any boxes made as the result of this video series will likely stay in whatever configuration they are first assembled in - BUT - the possibility exists to cater for that outlier job with relative ease. I am working on finishing this video series but it is taking a toll - I hope I can get there. Regards, Martin

Long time no see, why not cast as one not four

@olfoundryman8418

2 жыл бұрын

One not four - yep, fair comment. Indeed, the first metal box I made - nearly 60 years ago - was in fact a one-piece box, it was only about 125 mm square and possibly the worst castings I have ever made, even so I have use it a fair bit over the years. It got a mention in my “moulding box journey” video. Luckygen1001 tends to use cast in one-piece home-made boxes too. I could have done it this way but there were problems. Firstly, to make a 250mm square box would have needed a 350 mm square mould about 125 mm thick. While I could roll a mould this size over, I could not pick it up - just way too heavy. I would therefore have had to have grovelled around on hands and knees on the floor and I hate that! Secondly, to mould the sand retention ridges and the pin lugs would have required the use of several cores with all the problems that entails. Thirdly, I could make the 4 moulds for each of the sides individually way quicker than I could this one big mould - I could do it standing at my bench and I could lift them. Lastly, and this is the main reason, the idea is to mix and match the various box side lengths to suit the job at hand and even to extend them with suitable shaped bits of wood (or whatever) when the need arises. This will become apparent when (if) I manage to finish this video series but this depends on health improvements and in particular the finding of a successful pain management strategy- my back is agony on standing…..

Clickspring's latest clip (kzread.info/dash/bejne/hIl3m6xxqb3AlLg.html) from the hand powered drill flywheel casting (kzread.info/dash/bejne/gaiLuKNwj5y4mc4.html) sure looks to employ awfully familiar ways of working - I sincerely doubt it's entirely a coincidence. The original video has been seen by nearly two million people. That's some reach!

Johannes, Its certainly not a coincidence. I was in contact with Clickspring prior to the making of the original, clearly he saw benefit in adopting at least a version of some of the things we discussed. 2 million views - yep, that's a lot - clickspring is rightly very popular. I sure wish I could get even a tenth of that!... Martin

You have, directly and indirectly, assisted a great many of us in our endeavors! Even if you never upload another video, be secure in the fact you've helped to preserve many tricks and tips of your trade, and passed them along to new generations. I know I have told you this before, but once again: my sincere thanks.

A lack of a recent post is concerning to me. You ok???

Amalgamous, Thank you for inquiring. Am I ok? - Well sadly, no! I recently had yet another round of back surgery hopefully so I could stand up for more than a few minutes without being in agony and maybe even walk properly. Getting this far in this video series was a real trial of will over pain. Some of the pain has eased a little but I can still do almost nothing - very frustrating! On top of this I am constantly tired and have absolutely no energy. I have more medical stuff to go through in the next month or two, which may or may not involve yet more surgery - but it is unknown if the outcome will be any better. I would love to be able to finish this video series and I have big plans re that and about dozens of other videos. All plans on hold. What is so frustrating is that I see other YT videos done by people who have little idea of how to make a casting. Basically they butcher the art which offends me to the point of feeling quite ill - I have had to stop watching them. But they have the health and strength to peddle their awful methods and I am powerless to counteract their bad influence in any way - Grr! Maybe tomorrow will be better.... Martin

@@olfoundryman8418 Thanks for the update Martin. Back surgery is the worst, I honestly feel for you and I hope you feel better soon. Funny you should mention YT casting butchery, I was watching a hack make a YT video and that was what made me think of you and your channel. Had to watch a few of your videos to wash my eyes out. I truly hope for your speedy recovery. Cheers.

Gasper, Thanks for thinking of me. I am alive, but OK - eh not so much. Nothing terminal (as far as I know) 😊 but enough to stop me from being able to do more videos at the moment. Its a horrid situation for me as I have so many videos in mind to do.... Martin

Something my grandsons will never know about: working on cylinder heads. 🤯 Love the work and snippets you toss around Martin, always good info for the neophyte.

Uncle, Never know about cylinder heads - lucky them. 😊OH! The blown gaskets, the grease under the finger nails, the skinned knuckles, stripped or rounded nuts, broken studs , cracked blocks, leaky exhausts etc etc - sigh.... Martin
