I have just been on their site & bought a tin of Hobbys & re-stocked on H&N FTTs Thanks for the suggestion !

Just looked at a thread on an Airsporter that I'd left open in a tab, and apparently the thing to do for more umph is to longstroke it. Bet that requires a lathe at the very least and probably some rare arcane imperial thread only used by BSA and Sopwith on their WW1 Camel biplanes .

Nah. You just chop the Centre pillar that the piston head sits on toss away the buffer washer and re drill the retaining pin hole. It’s about 5mm. Then grind out the end of the slot in the piston with a file or dremel so it doesn’t smash into your cocking lever and there you have it. 16 fpe and will kill a Tiger tank with one shot or chop the spring down and you have a practically recoilless 11.5 trad tap loader. Easy. Can be done with hand tools. HAND TOOLS.

Here you go, Mr Robb will explain

That's for the later type, mines a Mk3 so still got that weird pointy piston that the mks 1 & 2 have. There is probably still a way to do it, there's usually a way around most things . I'm thinking that the pointy bit was a way to reduce TP length.

Maybe the pointy bit can be machined down a bit & given a flange for a parachute seal ? Gives me something to think about rather than listening to the nit wits at work

What no boing yet ?? Mellow middle of the week, barely more than a week to go boing.





Got the action of the Model 50 back together last night with a piston sleeve, I can tell the Titan spring is going to be way better just from compressing it into the action.

that'as fine for merely increasing the stroke with the std crappy BSA piston head/o-ring arrangement - and it does help. But if you want really soft shooting, the diana 28mm parachute seal is a little more work..

Excellent; nicely done. And well done to Gary for locating them.

If drilling and tapping you must take great care not to snap the tap off thus ruining the piston.

It wasn't me guv, honest.

indeed, but if you read the thread and those linked from it, you will see that there is no need to drill and tap the piston. you just thread the spigot instead.

.Sleepometer says 10 to go for the Saturday peeps.

Just a week for Mike and a week 'n' a smidge for some other mega lucky peeps.


Model 50 and new spring combo sounds promising.

BOING!

[TonyL]

I was going to go ding-donging at the Bell Target yesterday evening. But instead chose to have another go with that new-to-me 97 (refined zero a little, now about 10mm low at ten yards) and had a nice half an hour or so also with the Vantage.

BOINGY UPPIES!

I've re read it. I tried the aussie seals adapter, two questions, does the spigot need to be turned down before threading and can a die cut all the way down to the piston body?

Isn't it about time for Craig to tell he is rushing to nail a gun together?

obviously the OD needs to match the thread the die is trying to cut. From memory it's around 8mm, so if you choose m8 (or whatever matches) you are good. Then thread on your alli head.

The aussie uses a bolt IIRC... if you change that for a female countersunk version (aka a nut), you are fine again. Just thread the nut onto a threaded bolt, backup up against another nut so it's tight. Then turn it against a grindstone to get the conical shape. Cut a slot in the face for a large screwdriver bit.
