tube straightener

[magicoolbus]

It is super easy to straighten out the coiled tubing. All you need is a length of 2x4 and a couple pairs of hands. Straighten the coil mostly by hand, just get it close. Then you and buddy (my wifey helped me), roll the tubing between garage floor and the 2x4. I takes a bit of time, but you will get a very straight piece. A 2x6 would make it even easier as the rolling distance would be longer and you wouldn't have to reset the board as much. Good luck.
