Hello,

I know this topic has already been discussed but I am still having
doubts
.

As of now this is what I plan on using:

1. A 50ft roll of 1/4" OD refrigeration copper tubing.
2. A 3/4" thick sheet of plywood as the base.
3. 5 supports in an L shape cut out from a cutting board I got at
WAL-MART
fixed to the plywood base with screws (similar to the image below).

This is very close to my first try and set up

Some people prefer holes in the supports; others prefer notches. I am
not
sure about this.
The notches worked for me , I only threaded the tube through the first
set of inbd holes , then the rest was notched and used a little hot glue
because it would set quick


Say I want 15 turns. While winding the tubing, let's say I run out of
tubing  Slice is OK with short piece of wire in the tubes


A guy at Home Depot suggested to unroll the tubing on the floor and then
wind it on/through the supports.

 The guy at home depot never wound a coil , trying this will work harden
the coil , , start inboard and work outboard.

I appreciate your time. Thanks for the help.
