tubing straightener

Hard lines can be bought in straight shortish lengths, or in a long cheap coil.  You can use a tubing straightener to straighten the coil.  For some weird reason these are really expensive.  I am waiting for some Summit parts so I thought I would make one.  Here is one you can buy for $200 from Eastwood:

I bought these rollers from Lowes ($6 for a pair):

Plus a piece of angle chopped in half and a couple screws:

Does alright:

I got this in the mail tonight:

Brick of coke?  Nope, something way better: 

This is the first time I have really sat down and spent time with the handbook.  I suddenly realize that it is the reason everyone seems to know so much about everything.  I can't believe how many questions I have had in my head for years that are answered so plainly in here.  Best $45 spent in a while.  So I am still $140 ahead of buying the Eastwood straightener...
