Why do you go for 71mm stroke? What stroke length can be achieved without adjusting the slot in the piston?Originally Posted by T 20
I measure the stroke and cocking lever gap and do a quick calculation before I start machining.
Then I machine the front of the piston back by the amount needed to end up with a 71mm stroke, naturally this leaves more of the latch rod exposed.
After threading the newly exposed latch rod I screw on an alloy or delrin arbour to take the synthetic seal.
A quick tickle with a Dremel on the rear of the cocking lever slot in the piston to give a 1mm clearance on the cocking lever and it's good to go.
I'm a bit concerned about weakening both the piston skirt and the piston rod attachment.
