I have a Pro Tools HD also. Put studs in the garage floor. Manually bent my whole car. Lots of bars got redone. Never had any issues as far as fatigue or not enough strength. I think that hydraulics are over rated, unless you plan on doing lots of cars. There is lots of good ideas on youtube for knowing how much material is required in any given bend. I have several bends made marked in increments. Makes measuring much easier. Made up a little clamp to mount an inclinometer on it to keep the tubing level. A high quality tubing notcher will be your best friend.
