I'm in the process of tearing down my 73Z project car, and decided to make all new brake and fuel lines now.  To save some money and not have to piece several pieces together, I decided to buy 25" rolls of tubing.  I wanted to start with straight tube so I looked in to buying a line straightening tool.  Well they wanted $100 for one and that was more than I was willing to pay, so I made one.  This will work on 3/16, 1/4 or 5/16.  It cost me $15 to make.  Attached is a picture of it.  If there are others interested in making one of these, let me know.  If there's enough interest, I'll write up detailed instructions on how to build one.

I think you'll find that there's more than enough interest. Heck, if you wanted to make them, @zcardepot.com would probably sell them.

Yea, I'm interested.

Are the upper rollers fixed or adjustable?

Cost you only 15 bucks to make? Man, i'm also interested to know how you made it.

Ok I'll write it up and post it 

And yes,  the upper rollers are adjustable

OK Here are more detailed instructions on how to build one of these.  Two files attached. One is the drawing with dimensions and a material list.  The other is detailed assembly instructions with pictures.  If you decide to build one, I suggest reading all the way through the instructions before starting.  If anything is unclear, shoot me a message and I'll try to clear things up.
