Full power BSA meteor....

[TonyL]

Not sure if this has been mentioned but didn't John Bowkett do a full power Meteor.

He did indeed, I always fancied one back in the day.
He advertised them in the classified section in the AGW magazine.
Les..

Yep; remember that.

[TonyL]

I did one when I first joined Tone but if I recall you posted another that had been done years before. Jon Bud did say the piston weight needs to be raised and I have not been able to get a steel top hat to work towards that.
You are welcome to look over all my efforts at the bash.

Thank you, Tom. Yes, I'd very much look forward to that.

I might be receiving a freebie Meteor soon. Rifle won't cock. Guessing the buffer will have badly degraded and gummed up. Thought I'd look for a good Meteor fettling thread and they probably don't get better than this!

They sure have their own charm! Which mk are you getting?
Going for a full conversion with HW seal adaptor and steel tophat?

I got one of Welsh Willy's parachute adaptors which gives a fair bit of increase of stroke but I have not tested the power improvement with it. Good for those without a lathe or without patience. You just file back the cocking slot on the piston so it doesn't smack the cocking lever and bolt the thing on.

One Meteor I bought had that problem, and I diagnosed it with dyslexia as the spring which it was fitted with was one for a Mercury, gifting the little rifle with a most indigestible form of spring-binding.

Which I then think developed into the Supersport.

£23.50 including an oversize barrel hinge bolt fully adjustable in the style of HW35/HW80 etc. Not including the rifle

Oops!

At present, I'm not sure as to its age. I'm guessing it will be about 45 years old, so a Mk IV or V, perhaps? We'll know for sure when I see it.

I was going to simply fit a refresh kit from Protek to keep the cost low and add some weight to the piston. Their kit includes the spring, seals and new, uprated buffer for just £20. But then I wasn't aware of the WW conversion kit (thank you, Alistair). So, once I have it and strip it, if the cylinder seems okay, I might go for the WW seal kit.

.... if the cylinder seems okay....

That is always interesting with meteors, they can vary quite a lot.

yes, a byproduct of the "roll up a some cheap sheet into something vaguley tube-llike and braze it" manufacturing approach

I found a long thick walled 1" brass tube some years ago, and has used it as a hone on a problematic meteor tube.
With some emery paste, oil and patience, it removed a few high spots and made a good increase in velocity.

Certainly something to be prepared for.

Mr Bowkett used to get them upto nearly the legal limit back when he played with springers

Tone. If it has a couple of holes at the rear of the cylinder and it has the black finish it is a Mk5 if it is blued with a Gamo trigger it is the Mk6 and you won't get high power out of it. Assuming there is no rear sight and you have a metal lug sticking up at the breech end of the barrel it is a Mk 3. No lug and no holes makes it a Mk4 unless and I almost don't dare go here , it's a Mk1/2

I still think a steel top hat would be a good way to go.
Honing the cylinder as per Everts advice seems to work wonders, I only used a plastic tube with copper 22 mm pipe inside for strength with wet & dry glued until it disintegrated on my best effort* but I could feel the ovality and felt it reduce.
Of course you may have time constraints and are probably not obsessive compulsive.
I suspect Welsh Willys' parachute seal best deals with cylinder ovality but he mentions checking for it.

* The one I named Pepsi which you shot when we first met and does 11.5 with a standard spring.

I still think welding up a bent tube worked wonders in WW2 with the Sten gun.
