“Can you help with this”

[TinkeringTuna]

My friend has blessed me with his airgun/s to fix, that he left rotting in his outside cold shed for many years…

I have explained to him they aren’t worth anything but he has fond memories of them (one had a label on it still…..)

So I’ll tinker with them when I get a chance is how I left it, that was 4 months ago!

I suspect the top one is some iteration of Diana junior airgun / copy and the bottom most of us recognise as the extremely expensive B2 / or more affectionately the BK47 as it will fire no matter what it’s been through albeit not accurately.

Shockingly through it was surprisingly accurate at 10 yards, stood, freehand with .22 hobbies.

I took it apart yesterday and soaked the leather piston seal, covered with rust remover, light clean and fitted a brass port reducer down to 3.0mm ID after some time fiddling with a different gun.

Today was the day to get on with it properly

Sander out, wood first, wet and dry for the metal next as it was absolutely battered.

It isn’t worth bluing… likely prime it, some automotive paint and lacquer it, hide the pits I’m thinking…

It’s an £80 gun at the end of the day and I’m doing it out the kindness of my heart.

Could have earned enough today to buy him 5 of these new with change leftover if I did overtime instead, but it isn’t always about money is it…

That said he best appreciate it or we ain’t friends no more hahahaha

Still more work to be done, ideas for paint coating welcome (if it’s cheap but tough).

Thanks for reading about the BK47 battle.

Take care, keep tinkering.

Time spent looking after our friends is time well spent I reckon.
Let's hope he appreciates it.

Your dead right there mate, I'm lucky enough to have plenty of time and a well equipped workshop, and I derived great pleasure from being able to make parts for mates at the range, and they're always appreciative.

Makes me feel good, they get the bits they need, win win.

Try U Pol etch primer , it's quite a dark grey and looks fine as a finish , obviously being an etching primer it stays on

Some more work over the weekend tinkering… not fully there but much closer

The stock didn’t clean up well…. Some anti fungal took care of the majority of the issues, sadly there is a few splits which has deeply darkened and I can’t sand it out…. Was going to leave it quite pale/blonde for contrast but sadly those splits and some red looking wood in there wouldn’t allow it.

Currently running over it with Danish oil (was to hand)

Sympathetic-ish update for a £75 gun haha

needs trigger guard on and maybe some lacquer, few more coats of DO.

Hopefully he likes what I’ve done with it, even though it was a sympathetic tune up, I couldn’t disrespect the wood, it’s not its fault it got lumped with that mechanism haha

I’d say it’s pretty much sorted now…

Had to shim the breech block which has made a massive difference and a synthetic O-ring, I had to shim this in a weird way, layers with the upper portion being thicker / more layers… worked well in the end. Made a huge difference to noise.

Thrown a cheap scope on it for him with a manually adjusted parallax as best can.

Shots shown are 10m supported with a tripod, last central shot I actually adjusted it (was just being lazy for the rest).

Summary.

Wood - sanded, anti fungal, danish oil.

Gun:
Painted - sympathetically… Dads a panel beater, I could’ve gone to town… justified? Not for this no, so a quick spray over with direct to metal paint.

Aligned the front sight with a good whack for iron sight shooting as initial plan, it did work….

Polished crown, breech, new seal, shimmed breech block, sleeved the rather large port down to 3.0mm, revived the leather piston seal (needs a synthetic really…), cleaned and polished / de bur internal, flattened / smoothed the spring ends, re-lube, spring guide, polished washers x2.

8.5ft lbs and plenty accurate enough, all in all, perfect for their needs as a plinker.

Future, maybe… if he wants to… new spring, top hat, synthetic piston seal / o-ring maybe… Probably push it up to 10+ ft lbs, if the gun could even handle it… have seen elsewhere they can but I think that’s the newer models…

Doubt I’ll add any more here as won’t change much.

Better not send him my hourly rate or he could’ve bought 5 of these (wouldn’t dream of it for a friend).

Hope you enjoyed what started as my soft refurb that turned into a well over the top upgrade

Can’t help Tinkering can we….
