I'm a bit afraid to take too much off and have the piston coming apart during cocking.
As I started out with a 65mm stroke piston my machining for the TX piston seal is now within 0.5mm of the cross pin hole, so machining the piston face back any further is a none starter strength wise, Evert.

I'm pretty confident that altering a 99 piston could be my best bet --- but if someone could tell me the overall length of a HW99 piston I'd know for sure ?
