Piston gliding

[johnnytheboy]

I seen a few threads about gliding and buttoning pistons, they all relate to weihrauch, we’re any of the other guns like old bsa or we let’s ever glided?

AA are glided out of the box, as are modern LGV and LGU.

And the CZ Slavia 634 also had a Air Arms style rear synthetic piston bearing.

Most of the other makes manage quite well but HWs need all the help they can get.

It is more of a case of 'you can't polish a turd'

Gliding was popularised (pioneered?) by Venom and other 80s airgun tuning houses. At the time, most of their work was on HWs, hence the association between HWs and gliding.

You can button, glide or otherwise support both ends of most pistons, but it’s a lot easier to do well on actions with a central piston rod (HW, AA TX, etc) than those that engage the sear at the bottom.

What the hell is "piston gliding"?

If it just means making the piston fit for purpose, why not say so?.

im in the same boat bud, dont have a clue . would be interesting to find out tho.

Can it be done to those that engage the sear at the bottom?

Will Delrin/nylon buttons eventually leave wear marks on the cylinder?

Yes, I think so.

No. Probably.

Plastic wont abrade steel - it is the basic principle of synthetic bearings.
