Hw80 Buttoned Piston And Transer Port Experiment

[tyephillips 0]

Hello all,

Does anybody know where i can get a buttoned piston for my 2008 hw80k or know someone competent to do it, also do you need to size the piston with buttons to the chamber together? or Is this a matter of biting the bullet and sending it to v mach?

I was also reading a very interesting blog from Tom Gaylord from 2008 ( link below ) regards a transfer port experiment with several transfer port inserts that could be installed from the outside of the gun in less than a minute.

So just woundered if anybody has done / experimented with this before and the results? as would like to have a try with this myself if someone here has the engineering expertise.

Tye.

if you knew what you were doing you could do buttoning your self .On the net some where some one does it with a blacken decker drill ,some one else does it buy sticking the buttons on .you make the buttons over size first then turn ,file ,or polish down in size to fit cylinder exact. I have read the transfer port is better left alone .

Thanks for the info but I would not like to attemp myself as not that good at that sort of thing and run the risk of perniment damage etc. the transfer port was just an experiment idea to see what sort of results and if anyone else has done it.....

Thursodog is probably the man to see on here as regards buttoning pistons mate, it can be an awkward process if you don't know what youre doing, and to be honest I can't it being much better than making a piston liner from a pop bottleif the pistons not a great fit?

I live in west london,I have done buttoning to a gun of mine . Do you past west london ever .I would like to say I will do it ,the fear I have is the responsibility ,the job it is not a big thing .The only problem I could have is if the piston is hardened but I dont think it is .most of my cutters and drills are just highcarbon steel and my lathe if it still runs is a piece of chinese rubbish.

Thanks for the offer barrywhite I may take you up on that next time in the west London area but living in Essex at the moment so could be while, I going to contact v mach for details and prices etc and get back to the thread with results.

 

cheers

A seller on ebay is making lazaglide pistons for the hw80 http://www.ebay.co.uk/itm/Weihrauch-hw80-lasaglide-venom-piston-maglaza-/151111380458?pt=UK_SportingGoods_Hunting_ShootingSports_ET&hash=item232ef0adea

Cheers Gurtwuz.

Not a difficult job but requires a bit of attention to detail.

The sizing is the critical bit.

Those ebay pistons look the dogs.

A piston liner and a hone to true up the cylinder bore help also, I've seen a couple of 80s that are a little tighter at the thread end compared to the barrel end.

Tune the trigger and set to 2lbs to get a brilliant

 

ebay will take the work out of it.
