Coiling soft copper
|

Making my wort chiller tomorrow. Was messing around with my copper and couldn't get it to form without kinking. I know someone will have something great for me.

If you have a cornie, use that as a form.

There is a tool out there for forming copper that is essentially a spring that you slip the tubing through so it bends evenly without kinking.
Edit: Google says it is called a spring type tube bender

I wrapped the tubing around a paint can for my immersion chiller.

I used my cornie. If you do this, hold on to one end of the copper and roll the cornie on the copper so it winds the copper on the cornie.

First of all, if it comes in a coil, don't uncoil it. More likely than not you'll be needing a smaller diameter coil than it comes rolled as. Secondly, use a form. Any cylindrical container will work (I used a tupperware container that was close to the size I needed). Drop the whole coil over the container, grab one end and slowly wrap the rest of it around the container doing little sections at a time. It shouldn't take a great amount of pressure.

Careful work has allowed me to do larger radiuses and the spring bender works for smaller radiuses. If you want to get fancy, fill the tubing with water, cap the ends and freeze it. Then bend and form your tubing while the water inside is still frozen. This method will allow you to get some very tight bends.

A lot depends on what size tubing you are using and the radius you want to bend it to. The typical 3/8" OD tubing isn't difficult to bend without kinking it, but anything largeer than that can be challengind. The larger the diameter, the more difficult it will be to bend. A corny keg works pretty well as a form to ben the tubing around. Gentle, firm force works best.

An easy way to coil the copper tubing around the corny is to; lay the corny on the lawn, unspool a little of the copper tubing, place it under the corny, holding one end of the copper tubing roll the corny over the tubing. Easy to keep tight rolls...no kinking of the tubing.

Too much bending will work harden the copper and it will become brittle.
