After action report.

I had access to a 55 ton hydraulic press. It took some effort to create fixtures to securely hold the stick so it wouldn't go flying out of the press. The stick as delivered from Van's had approx 10 3/4" diameter between inside surfaces. Packed stick with sand. Went slowly with first one. Discovered needed 3/4" of compression before getting any permanent bend. Compressed it to slightly under 9" measurement, which after release of pressure gave a 9 3/4" dimension. That was just right, as I could see the tubing just beginning to slightly deform. Second stick came out within 1/8" dimension of first.  Now have full up and down travel on elevator without stick grip hitting panel, although knuckles might get a little bruising if really need full nose down. Back to working on the 90% of remaining 5% or something like that.

 Guys as an ex-plumber, the sand idea gives the perfect support to prevent kinking. Use dry send and pack well

 Warm regards
