Looking good, Mick, and looking forward to the finished articles from you and CraigyBoy breathing new life into the lovely old '35.
At this rate, even TinnyBum's going to gate crash the party!

Have you considered a piston without bearing by the piston seal?
Agree Mick. As you cock the rifle, most of the load is taken by the rear bearing surface. I consider the load at the front of the piston to be negligible during cocking, the seal being able to take this load and as you fire the gun, the only force is on the axis of the piston (if you ignore moment on this axis induced by the spring). I have modified the piston of my Diana 35 (old) with no front bearing and it works fine.
Less friction = more power and more consistency

Hi Bruno
Thinking about it, the Diana 35 and many other Diana break barrels would be ideal to convert to rotating Pistons due to their sear rod and trigger arrangements.
I'm on my last rusting of the HW35 cylinder before it gets dunked in Kerosene for 24 hours to harden off, so hopefully I'll have this 35 up and running by next weekend.
Be great to hear what it's like once together, Mick.

What are the advantages to having a fully rotating piston?
