How to wind a perfect coil condenser...

I would expect this topic to have multiple posts by the same person showing us how to do something. If there are pictures, let pint_o_shine know and he can host them for you.

I was gonna say, time to break out the die-grinder and turn the eyes into hooks. :)

Froze it this time and still crushed the tubing. I'm looking, now, to buy a coil from someone who might help me.

It doesn't matter if the pipe is flattened, so long as it's not kinked.

Forget water, fill it with table salt. No kinks, no flattening.

I removed the salt after the coil was wound by using self sealing silicone tape to attach and seal the tubing to a hose bib, turned the water on full and left it there. It took over an hour for the water to penetrate through the salt, dissolve it and blast it out. But blast it out it did.

You need to make sure the discharge end is pointed in a safe direction. When the salt finally lets go it gushes.

I tried using one of those spring benders. It made my fingers so sore and tired I just threw the whole mess away after a few turns.

Instead of using eye bolts to hold the tubing to the jig I used hose clamps (aka worm clamps).

I used salt and duct tape to hold the tube to a mandrel. Worked great the first time and cleared just like Kapea said.

Question on use of spring bender - is it just needed to establish the first 90 deg turn and then first wrap around the mandrel? Or is it advised /needed for all the coil turns on first and second wraps?

If you wrap slow I never use a spring bender, I also found the silica sand to work better than salt for cleaning it out afterwards.

I carefully hand-bent the transition from tubing parallel to the mandrel to coiling around the mandrel, and back, at the end. Go slow. No need to rush it.

Winding the coil took about 20 minutes. Find the pieces for the jig, and building it took a couple of days.

Silica sand sounds good too, but it is not soluble. If it gets plugged up inside the coil you've screwed the pooch.

I use a very fine grade and have built over 12 for different members and never had a problem. I don't use any liquid to get it out but just compressed air.

Coil building sounds pretty lucrative... :lol:

o.k. so the title doesn't say copper coil...

CSST Flexible Stainless Tube. I've made six now, all work well and never ruined an inch of tubing.

If it's too tight or tails are wrong you can straighten it out and try again.

Dad300:
Can you post a link to finding that stuff? I haven't seen it on EBAY or listed elsewhere, reasonably priced, without some plastic coating. Thanks.

A guy on EBAY wants $56.95 for 25 feet of 1/2 inch uninsulated FSS.

Suggest that may be reasonable. Compare this...

...and you've still gotta peel off the plastic. :doh:

$2.25 a foot here for uncoated, but I have gotten it off ebay for as little $1 per foot shipping included.

I have gotten it off the shelf at ACE Hardware also.

DAD, I have tried 3 different SS flexi lines and still cant get one in a 2 inch pipe. They are advertised as 3/8 inside and 1/2 inch outside but they aint. More like 7/16 id and 5/8 od. Where can I get a 60 in. gas pipe the will wind to fit a 2 inch pipe.
The coil has to fit down into a 2 in. TEE or I would change the top out for a short 3 in. pipe.
