Autumn 2013, Little update what I have been upto

So…..the lathe blew up, typical Chinese lathe so my mates tell me, DC motors and carbon brushes that over heat…etc etc, so its all stripped out and will have a new 1HP 3ph motor installed with Inverter/remote start stop/speed control. This means not much springer tinkering while i saved for the new motor etc…BUT that […]

HW77, the parts, tuning and upgrading, even on a brand new gun.

Edit, seem this was not loctite or glue but excessive bluing salts hardening on the threads between the trigger block and the action. I have been advised a good soak in dewattering oil/release agent should have helped. Regards how long to soak…i was told at least 1 full day. After waiting months for a new […]

Diana 280 piston, where to correct if nose is out of round.

Decided to pick up another D280, this one is .177 and full rifle, the extra barrel length really helps the gun IMO….if you want the K version get a .22. So….again i checked the piston and again it was rubbing on the compression cylinder just behind the piston nose…so I figured I would show some […]

Something I dreamt up….recoil and surge dampener.

This would lose some spring room but in theory would counter piston bounce. O ring placement would need to be experimented with to ensure enough compression happens, this is just a rough idea to get some creative juices flowing.

Busy with projects but will be bringing new posts and info soon

Most of the early projects at AGT have been with HW rifles, HW95’s and 97/77’s and HW80, of¬† late however I have entered into a love affair with Diana rifles, notably the M52/54 and the 440TH/430. I am sorry to say I won’t be testing or tuning the T05 or earlier triggers, I personally have […]

Specs for the build were exactly as I outlined in the post above except for the transfer port, this was opened […]

Could this be the ultimate piston seal?

Been looking for an alternative seal now for a while, something off the shelf, easy to find and that works as well as an O ring if possible with minimal lost volume. Scouring the Hydraulic seal suppliers I came across Kastas. Click the pic for a link to the site, I highlighted the seal I […]

Weihrauch HW35 LGV

Back in July2012 I had the idea of building a Weihrauch HW35 fitted with a Walther LGV rotary piston and that’s just how it stayed until Christmas — just an idea. Then in December I was fed up one Sunday¬† and decided to de-braze a HW35 cylinder from its breech block in order to show […]

Revisiting the Diana 52 Carbine

Event though I had the D52 shooting quite nice, i knew it could be better…with the Walther LGV piston being such a universal base for conversions I decided to see if it could get it to fit in the D52 and by making up a new longer piston rod reduce the stroke…and of course sleeve […]
