Hello,

I know this topic has already been discussed but I am still having doubts 
when it comes to the winding of the copper tubing through the holes or 
notches of the supports. So if someone could clear this up for me that 
would be very much appreciated.

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).

At first I thought of fixing the supports to the base and winding the 
tubing through the holes, but now I am realizing it will be a PAIN!! 
Therefore, should I slide in the supports, starting at the center and work 
my way outside, through the entire roll of tubing? Or should I start at the 
ends and work my way inside?

Some people prefer holes in the supports; others prefer notches. I am not 
sure about this. I am thinking that the notches might bend the tubing if 
one is not careful when doing this. Any suggestions?

Say I want 15 turns. While winding the tubing, let's say I run out of 
tubing on the 11th turn. Is it okay to solder another continuous piece of 
tubing to the original, to complete the 15 turns or not? I guess, what I am 
asking is if I need a continuous roll of tubing or not? Will this affect 
the coupling and/or the overall performance of the TC?

Another thing I noticed is the fact that the tubing is double wounded, 
making it even more tedious to work with it. A guy at Home Depot suggested 
to unroll the tubing on the floor and then wind it on/through the supports. 
Any suggestions?

I appreciate your time. Thanks for the help.
