This is how I went about to quickly make a coil of copper tubing. This 1/4 inch tubing is left over material from air conditioning units.

Step 1: Something to Roll On.

I used this pvc pipe to support the tubing while I got my Roll on.

Step 2: Rolling It.

Starting with an end held it firmly To the pvc pipe and gently wrapped it in a coil. I kept firm pressure pulling away from the pvc to ensure kink free coils.

Once done I used my tubing cutter to free the end.

Step 3: The Finished Coil.

Sliding the new coil out of the pvc pipe, here is my first ever hand rolled copper tubing coil.

I lesson I learnt is that the bigger the diameter of pvc pipe used the better the results as in zero chance of kinks. Typically at least 10 to 1 ratio of diameters for pvc pipe to copper tubing.
<p>To prevent copper tubing from kinking. Fill the tubing with water and freeze it. </p>
<p>I prefer sand for large tubing, or low-temp alloy (i.e. Woods Metal) for small diameter tubing.</p>
