Review on Tool Guy Republic Tubing Straightener by Marc Stewart

If you do 3/16 or 5/16, it works great. If you try 3/8" tubing, the rollers will flex and along with the sharp edge on the rim of the rollers will push the cord into the tubing. A few back and forth movements and the tube literally becomes square. I did this with cupronickel pipe and it ruined 20 feet of pipe. it's useless. IT IS SQUARE NOW lol I have tried 3/8 stainless steel and the wheels flex so much they are rubbing against the frame. great idea, poor implementation. Sit back and hit the frame. All in all I highly recommend it if you ONLY make 3/16-5/16 tubes.
