Planning for some piston weight tinkering?
Feeling somewhat Patriotic this weekend, and not wanting you good folks to think that I only appreciate fine Airguns from the Fatherland, I thought I'd show you my BSA Mercury ratting rig.
For some strange reason I rarely show this to anyone and it's never been used at the Boinger Bash. :-

Unfortunately, when I got it the previous owner had decided to customise the stock into a skeleton stock and had tastefully added some images of flying pheasants --- Sparing no expense on this gun I wrapped the skeleton stock in electrical tape. :-

To take care of the infamous BSA barrel wobble I lovingly fitted a 1/4" BSF bolt through the breech jaws and Meteor MK 5 barrel.

Now when I say this is my ratting rig, I don't mean it's shot hundreds of rats --- it's killed thousands.
And the reason that I've got it out now is that I've decided it's time that I gave the old girl a service/tune and a little makeover --- I actually bought a new stock for her ten years ago off here.
She's probably the best £10 I ever spent.

Planning for some piston weight tinkering?
Too many airguns!
Funny enough, evert.
I'm just sat here with a calculator working out how many 12mm holes I'll have to drill in the piston body to remove 50grams in weight from the 300gram piston before adding 20grams of liner and top hat to take it back up to 270grams.
Looks like 30 is the answer.
I'm also looking at weight reduction of the ally piston head which is about 20grams from memory.

Those pheasant pictures are something else - they remind me of a magic lantern investigation into whether a galloping horse ever looses contact with the ground. Perhaps you could place a series of rat pictures in there?

I've got some slug guns.
Great guns Mercury’s one of my favourites Judging by the number of vermin it as accounted for it has earned a little TLC great post mick

Far too many rifles to list now, all mainly British but the odd pesky foreigner has snuck in
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
You could sell that stock described as new in the sales section, electrical tape included As fashions come and go I wonder when we'll see a revival of hand carvings and hunting scenes.
I shot an Airsporter for the first time at the last boinger bash and it was nice to shoot.
You can't beat a good ratter! Nice one, Mick.
Much preferring your breech bolt to the factory's attempt, too.
THE BOINGER BASH AT QUIGLEY HOLLOW. MAKING GREAT MEMORIES SINCE 15th JUNE, 2013.
NEXT EVENT :- May 17/18, 2025.........BOING!!
Ah, Jon.
I'd be happy to carve out a couple of slots with an angle grinder but I reckon the piston would be stronger if I just drilled it to lighten it.
Besides which, I also like the idea of having my piston looking like a piece of cheese off Wallace and Gromit.
All the best Mick
There's the thing, James.
The Airsporter and Mercury has the same bore and stroke as my Original 35 which is such a nice firing cycle it inspired me to have another look at my BSAs.
As the Mercury uses the same piston as the MK4-6 Airsporter, I'm hoping to upgrade my two Airsporter S when I've settled on a tune for the Mercury.
All the best Mick
IF iI remember correctly, my own bastard Mercury has a piston milled for a sight rail. That might help a bit?
Too many airguns!
best airsporter tune is to chop the spigot, thread m8, stick on adapter for a diana 28mm seal, job done. +5mm stroke and a seal that actually works, transforms them.
