BSA Meteor Disassembly, Part 2

On I go...

You can see the small setscrew that adjusts the trigger bears against that pin.

The front of the trigger blade and the screw. So you have to take the gun out of the stock to adjust the trigger?

Pushing out one pin.

But the trigger is still connected...

Pushing out another pin...

And it's still connected.

Final pin.

And out comes the trigger group.

Milling a tool to take up the spring load.

Just a notched tube.

Pushing it in.

Not far enough though...

Lengthen the notches.

Now push that pin out. Again, it looks like the pin on the Superstar.

Really a thing of beauty.

After all that, this is the amount of spring preload.

The spring and guide.

The guide and washer.

The piston.

I don't know what that yellow stack is...

An o-ringed piston head. Easy to replace.

The piston head fits into the piston via a slot... Looks a bit worn and the head was loose.

The piston head stem.

A steel washer and a stack of poorly punched yellow plastic washers, likely a replacement for what should be a rubber or leather washer.

Lots of washers. Well if you don't have a lathe...

The piston head.

Anyway I have to clean it up now, make a new washer for the piston head, lube and reassemble, then do the stock work...

BSA Meteor Disassembly, Part 1

I picked up this BSA Meteor the other day on the Yellow Classified page. As with most of the airguns I buy what got me was the description of how beat up it was. Chambers has exploded drawings of all the Marks (versions) of the Meteor.

Doesn't look bad in a tiny picture.

BSA METEOR. Grooved for a scope.

B.S.A. GUNS LTD. ENGLAND .22 CAL, which is good as I'm sick and tired of .177 springers.

This one must have been imported by ITHACA GUN CO. INC. ITHACA N.Y.
I've seen other BSA airguns with this mark on them.

The rear sight is missing. This sight mount tells me it's a MK5, although the trigger (OK, I'm getting ahead of myself) says it's a MK4. Who knows.

Time to remove some screws.


The other side had a different screw and washer. I'm assuming the one on the right is correct.

Wallowed out screw hole. I'll likely make some screw cups.

Just like the Superstar I worked on...

The trigger guard.

The stock has some cracks that were glued...

Looks like it split...

And the end...but most seem solidly glued. I'll definitely be sanding the stock down, checking for other cracks and for the integrity of those repairs.

Plastic end cap.

Gamo uses a similar cap.

A cross pin holds the spring in.

The pivot pin.

Pressed out.

The pin is in good shape.

The cocking shoe is ugly but not terribly worn.

With the pin out the spring detent can be removed.

The chisel detent.

The tube is welded together from sheet.

More to come...
