Awesome, Dan! I'll definitely have to try this technique. :D In the past I've used sand for bending copper tubing with, um... mixed results, and getting all of the sand back out is... "fun."

You are the man Dan. I appreciate all I have learned from you. I hope you and Denise are doing well.

Nice tip. I will try that. The other day i was bending copper tubing and it ended up with all kinds of kinks. Thanks for sharing. Hope mom, and the rest of your family are doing well.

Hi Keith, We all are good and thank you for the nice comment. Hope all is well with you too.

Great way to get the job done. Sand or steel shot is harder to get out and still flattens a bit. I like the way you are always looking for a better way to get things done.

Nice! Neat approach to the "problem". I like your style.

Finally I find a useful technique to bend a Copper Pipe into a Spiral, other Techniques on KZread Included Filling the Pipe Either with Fine Salt, or Fine Black pepper...neither ways worked out for me, and I had to saw the pipe to unclog the bended Pipe, I think this way should do, now back to the Hardware shop to by more copper pipe to try & bend, Thanks.

U-groove bearings can be used to get tight bends with a bending jig remember you can bend a coil diameter of 4x the diameter of the tube you are using so 1/4” tubing can be wound into a 1” diameter coil minimum

Excellent... might have ta tinker my way towards this concept...im just routing the water up to the solar heat collector right now

This is amazing, exactly what I needed for my project

What a great idea. Thank you. I have heard about a special metal that is used to fill thin tubes before bending. The metal melts out with hot water.

Very cool video I have seen a very similar method to this with the exception of freezing the water inside the copper tubing. That method ensures that you can wind and/or bend the tubing as tight as you want without the slightest kinks or crimping occuring.

48 years a plumber here. Very fine silica sand, like the stuff used in ashtrays at hotels, is far and away easier to use than water.

very informative! thanks!👍

Longtime fan here. So glad to see you back. Well presented and informative video as always. Cheers from Australia

I have always loved your vids

Hot glue was genius... earned the like!

Hey Dan, when bending the copper tube around the larger pipe, it might be worth a try to lay the pipe on the ground, and tape the copper to the pipe, then roll the pipe on the floor, or on a work table. Take care to not crush or flatten the copper. Another way might be to use a short piece of pipe inserted into a lathe, or some kind of slow rotating mechanical device that you can use to wind the copper around the pipe without as much effort. I also believe that using sand instead of water is easier, but water seems to work well too. Thanks for the demo.

Been a while since I've seen a video from you guys. Not sure if KZread hasn't showed me or y'all haven't posted any. Love your vids

My dad had a flaring jig and a testing jig. They were both like locking pliers for copper pipe (half inch). He'd use them together for bending because the tester's little air pump could be hooked to a hose and put in a bucket. ... Though I don't think he used them to bend more than 45 degrees. Also, he put teflon tape on the flaring clamp.

Haven’t watch y’all in a while, dude you got jacked!

Neat concept...I just use my "Ridgid" tubing bender!

You both make coils with those "tools" ?

Welcome back Dan!!

Great tip about filling the tubing with water. The coil at the end of the video was perfect, but the twisted tubing in the first part of the video, not so much. Suggestions to improve is to use a slightly bigger rounded shape for the end of the twist, and fix it and the end of the twist securely, because it just looks like the tubing is almost folded in two and about to snap. You need a really rounded shape to keep the water flowing impeded. Also, instead of laying out the two copper arms in parallel on the table before twisting them, they probably need to form a V so you can take each arm and twist them equally. Using a small wooden structure that you run the two arms of tubing through and that you just turn like a key may ensure a perfectly equal twisting of both arms. Your device basically had one arm that's nearly straight and the other that's twisted around it, when what you want for a heat exchanger is the two arms twisted around each other equally. I am planning on putting a metal coil around a rocket stove-like chimney, behind the walls of the chimney of course, because these things get crazy hot, or maybe a double coil, one for water, one for air, if that does not affect performance too much. I need to check the temperatures and flowing volumes I need to find out which metals fit, or if I even need metal at all for the air flow, and what diameters I need for both water and air. Still a lot to do on the drawing table, all these ideas are interesting but could take me too far for too long!

He blew out the tubing and warmed it with hot air to make sure it was dry inside. Removing the salt was easy and rinsing with fresh water washed out any residue. One option if there's no fine sand on hand. I had some white sand for making mortar, stuff not used in an earlier project. It worked very well.

Hi, Dan Amazing video; great trick... Much better than the 'normal' sand filling... I need those copper coils for a inductive heating device (with different diameters..).. and wind these over a 3D printed jig.. Thanks a lot for sharing Fritz (from Mainz, Germany

Thanks for your video.👍🤔😏

1) Use compassion fittings and end caps to seal it... faster. 2) The more you bend copper the harder it is to bend. If you can't bend it where you want, let the water out and anneal the copper... Then you can start bending it more.

Instead of the crimp, hot glue electrocution method, consider putting your water filled copper in the freezer overnight and then bend your copper

thx! that coil looks perfect!

Nice trick. Thanks for sharing.

Thanks for the tip. I'm thinking that, if you insert ~ 1 foot of the copper tubing inside the 2" pipe, then wrap the tubing around the pipe, so the coil would wrap around its own inner tube with both ends at the same end. Perhaps then the stretched-out coil & its inner tube could both be spiral-fed into the water heater's tank?

even copper in rolls, already being annealed will work harden every time you bend it and stop. To "resoften" it, heat it to cherry red and let it cool slowly. This anneals (softens) it. you can buy a small bender for $10 that will give you a perfect bend, every time at it's minimum radius, given it's diameter in 10 seconds

They sell this magic tool called a tubing bender, you should try it. much easier than messing around with trying to fill with water and sealing it.

Fantastic video

as a Child at our summer camp we would just lay a 50 ft. garden hose out in the sun and in under a hour you would have enough hot water to take a shower, just make sure you have a sprayer end on the hose

you could unplug the glue gun and work quickly. they don't cool too fast. just re-heat (plug back in) for the other end.

Curious if you could run the stainless steel or copper tubing through the wall of a wood stove to heat a liquid for baseboard radiators. Not for sure if you could seal up tubing penetration points in the side of the wood stove or if the tubing could handle the internal wood stove temps. Also are you aware of any propane heaters which could be used with a heater exchanger like you've made here? I'm imagining you could have a propane heater which sits outside so venting is not a problem and the flame would heat the exchanger and the tubing could penetrate a cabin's walls and connect to a base board radiator. Maybe thermosyphoning could be used so a pump is not required.

Sweet. Great job

when you rap the tube around the pipe you should leave space between each wind to increase the surface area exposed to the water for better flow over the surface of the pipe.

It’s also possible to fill it with sand, or freeze the water inside it. This is how brass instruments are bent

This is great! Thanks

beautifull!

Dude you have bulked up a bunch since the last video I saw,, years ago,, stay safe

I have hooked up many diswashers and icemakers. Unless you are doing some crazy bends, I insert a nylon rope inside the tube and i can make 45 90 180 and a few spiran bends without deforming the pipe. The nylon rope comes out easy and if it is a long piece i wiput some dish washing liquid on the rope. No messing with glue gun etc.

Yeah more videos!

This is a good thing, to show others that are afraid to try Bending pipes. Now, Copper is probably the best of metal pipe, to bend, wheather you're making a coil pipe to transfer heat from the pipe of a wood stove, or doing something like what you are showing right now. But there are other types of pipe, some are special order, & are - not on - shelf, all the time. Hardware's are probably the best place to buy pipe for any purpose. Even pvc, pipe Can be bent. I use a propane torch, to heat the pvc, pipe to bend it, it's like anything else, practice makes perfect,. Now I funnel, sand into the pipe, before I try To bend it. I get the ( Play sand ) in bag's Put in a small baby swimming pool, from the Dollar store. That way I can work with it, Without it spilling out all over the place. The Play sand, I get is kinda sticky, & it's easyer to work with, and the pipe I usually get is 3/4 copper pipe. I have work with The 1/2 inch, but it's harder to get sand into, and sometimes" it will crimp" no matter what you do. I've made a pipe Bender, thats easyer for bending any pipe. It consist of Three Large Rollers, that can be changed out for smaller/or Larger, Rollers, they're adjustable" SO, That I can Work with the pipe I am bending" so, I can adjust the top roller, so - as to bring it down More & MORE as needed, also, The two bottom Two Rollers are also adjustable" so I can bring them, closer & closer to make a tighter" turn on the pipe.!! So, as to have a tighter spin on the coil of Copper pipe... Now" this seems to work best, on copper, pipe. However, it works on a lot of types of Pipes.!”⅝⁴! I've experimented on all kinds of other pipes. Okay, well, I like What you're doing, on you're channel, & I will keep watching, please make two videos A week, if possible.

Perfect thank you :) I'd like to heat mine using solar

Cool.. I never thought about creating a double seal with hot glue!! And using water pressure to keep from kinking. I want to build a hybrid boiler, with concentrated solar, and a wood stove to heat water, to heat water for home use and home heating, I'd like to use the heat from a generator to also contribute to the heating, being off grid, thermal consevation can save ALOT.. I'd like to make steam without any explosions!! To power a generator from the wood stove, while heating the house, in the process, using the house to condense the steam.

In Indiana this is a winter job. Fill with water... Leave outside to freeze.

Use a rubber cap like the ones for car vacuum lines to seal the ends then you can reinforce with tape on the ends

Nice.

Dan what are you up to these days? Miss your inspiring videos! /I often think it would be cool if you visited people and helped them with their projects!

You could also braze or solder the ends to make sure its sealed.

My dad worked at Pratt & Whitney Aircraft and they had a low melting point metal that they filled tubing with to bend it. It would melt in hot water. He told me someone made a mold and cast a spoon and left it at the coffee pot and when someone came to us it it melted in their coffee. They all had a laugh.

If you use sand will be much easier for you. You can tap it in there put a piece of tape over the end and it's a lot easier. A lot less chance of it leaking out, as its larger. You will be a maze of the results. You could also use salt. But I like using sand. Make sure it's dry it will flow a lot easier. You can do extremely tight bends without kinking.

終於回歸了

I would think the hot glue is preferable to solder anyway, since you don't have to cut the ends off (to avoid the lead contamination from the solder)...

if it's not too long of a tube salt or sand works well and should blow out with air or water pressure. basically any small granules that don't compact too much. you really need to support your bends around a round shape gradually reducing your radius. you went from straight to a tight bend without much stepping down and it looks half kinked.

@GREENPOWERSCIENCE

5 жыл бұрын

It is a bit but flow is good. The opening requires a 180 where the tube touches and if the inner material is too tight, the bend is either impossible by hand or will stretch the copper open on the outer curve basically ripping it.
