It's all gone very quiet on the hybrid Hw50 front, what are you hiding from us uncle mick

All the best

Get you some of that, John --- HW50 piston sporting it's sexy new TX seal, giving a 5mm longer stroke.


I'm going to have little kip now.

I only have a spare Hw55 piston that is now sitting here feeling quite inadequate, in that it is never going to be up there with the big boys in the power stakes.

I'm off before I feel totally obsolete but in saying that, as Arnie would say, old But not obsolete

Glad to see you've made a start Mick.

All the best

I did a similar conversion a while back, with a leather sealed piston, and got some velocity improvement- but not a massive one.
JSB express at 715-720fps, which sholud be right above 9fpe.
This was with a Maccari/ARH E-3200 spring, you can probably get a bit more with some spring experimentation.

Ooo-er, looking lovely, Mick.

Are you feeling fully rested again now?

Now you tell me.

Sorry, I do forget things all the time..
I mentioned it in the thread about Hw50 velocity, that one of my old leather sealed Hw50's was a bit faster than expected...
When I opened it up, I found the conversion that I had done previously, and forgot all about

Will be interesting to how munch velocity you get!

And an opportunity to experiment with different boingy things is never to be sniffed at!
