Review on Tool Guy Republic Tubing Straightener by Rob Bishop

I used this on a 3/8 aluminum pipe first. The tube was twisted so I laid it out as straight as possible and then started feeding it through the tool. To get the pipe straight you need to tighten the rollers a bit. This deformed the tube and made it almost square due to the shape of the rollers. I then tried 5/16 stainless steel tubing, same result but not as bad. With the 3/8 pipe it was so bad that I couldn't get the union nut onto the end of the pipe. I think I'll machine rolls with a precise 3/8 tube bend. Just take a look.
