Thanks. That was exactly what I was looking for. Do you think it is worth buying the pneumatic head for the build process?

I used the drawings (sent email to designer asking permission first) provided by experimental aero. I also had a local guy do the powder coating, as I think it might as well look great!

I see where others have put reinforcement, but do we know exactly where the flex is happening? I would think it would be in the upper and lower arms, but the reinforcement I see others making is at the rear transition between upper and lower.

Your are right, the flex happens in the arms, but the yield point is at the back where the arms are welded to the vertical portion. Most that build their own frame do it with thicker material to limit the flex and allow the hydraulic front end to do the most work. However the welds at the innermost point are right at the theoretical yield strength, so done correctly, this can be strengthened when constructing.

I definitely feel the Hydro-Pneumatic DRDT2 head is worth is, along with the hand squeezer. I just dimpled my forward upper skin and found it a breeze.

Be sure to use cold rolled steel. Stronger than the hot variety.
