Had you thought about reducing the rear of the piston so you still have enough piston rod to protrude through the back block and set the trigger.
Thanks for looking. Fancied a tamper with the 50 piston. It didn't go well.
First thought, machine the head for O ring or AA type seal. Too hard for limited tool/skill set.
Next, remove head and latch rod. Not easy. The thin tube is clenched into a groove around the head,
Fortunately the tube is soft enough to cut with hacksaw. Spigot on latch rod snapped and too hard as per head.
Plan is, make a mild steel/alloy/Delrin head. Anneal/rework/thread the rod end.
Objective is increased stroke. All physically possible medically approved suggestions welcome

Hw77+7
Thanks for the interest. No. Not sure what that would achieve
Mick put up the specs for making pistons to maximize old HW50 stroke some time ago.
Too many airguns!
