Here you go, Jon.
Here's the three strokes and weights of the three setups :-
Factory Synthetic sealed piston --------------------------------------- 69mm stroke - piston weight 264g
Factory Leather sealed piston ----------------------------------------- 65mm stroke - piston weight 294g
Leather sealed piston adapted via steel adaptor to synthetic ------- 61mm stroke - piston weight 321g
cheers Mick, sounds like another reason to just buy a factor synth piston and be done with it.. 30g will be noticeable.
the steel conversion head looks like an absolutely horrible option...

This is the piston I made for my last 35, Jon :-

Even that could lose a little more weight, but it works.
Brilliant information, Mick.
I remembered you had posted this before and that the weight saving was significant but couldn't remember exactly. Be great to have this info in the thread in Useful Information.
And I really must get one sorted for my old nail......that extra 8mm of stroke and 57g weight saving should make a huge difference.

I have long been sceptical of these conversions. This thread has changed my mind. Thank you.

I am, Jon.
When I first acquired the gun and stripped it, the original leather seal was well and truly goosed. I tried to get another leather one but everyone was telling me they weren't available. Then I rang Knibbs. Apparently in stock. Ordered by phone and it arrived......a leather to synthetic conversion.
Must admit, if I had far fewer guns I'd have done more work on it since its build (08/09), but it shoots very sweetly and I only use it for short range open sight garden duty. But I will be treating it to a later piston methinks.

hah - then you will notice a huge improvement. Got a std leather head & seal here if you want it - let us know.

Hi Jon,
Thank you for that most kind gesture.
However, it'd only be right to graciously decline your offer and see if it would be of use to someone in need. A few years ago I was considering going back to leather and nothing seemed to be out there. But then Dave, WonkyDonky, kindly gave me one out of his stash when I bought a 99 spring and guide kit from him. Then, a couple of years ago, I saw that Protek had some in so bought one of those, also. So I now have a couple for if I wish to try going back to leather (which might be a nice solution anyway with the larger TP) and, as they last for ages, will keep me going.
Still more than tempted to go for that newer, lighter, longer stroke piston, though!
