You don’t get anything thing out if you don’t put the work in.

I’m using molybdenum impregnated Nylatron for all parts with viton o’ring on extension. Give it a whirl eh!
Someone over in uk has done one and has had good success with it so more or less copying his work
After 4 years of using its still working good,so all being well will be less than just buying new seal.
Fingers crossed.

I turned up a top hat and guide for an HW80 out of delrin, and it was like it had snowed around the lathe with the amount you take off.

Turning all the bits up next week so will show photos when it’s about to go back together.
Just got O’rings coming down from Wellywood so will see how it goes.
Keep you posted. Parts less than $20 just an hour or two machining.
Using existing spring, would have liked original but will see how it shoots
The spring guide in it now is very loose so next one should improve the buzz.

Sounds like a good project there Stu. 
I'd be keen to see photo's of the O ring piston seal if you can be bothered. will you make it out of aluminium?

Hello Paul
Thanks for that offer, I should be ok a pretty standard size and available in Christchurch.
Existing one gone hard and cracking. Also doing piston extension with o’ring instead of standard seal
And the spring guide was as loose as so making new one of them and hopefully should reduce the bit of buzz.
Cheer’s

I have 2 spare from memory, but would need to check. If you can't get one let me know.
