BSA Meteor, Back Together

Just some details of getting the Meteor working.

I polished all the internals.

I needed to replace those yellow washers.

So I turned up a rubber disk.

I had to trim it a few times to get the length right. It also came out tapered as it was softer rubber than I usually turn. Live and learn. The main thing was to keep the piston head from rattling around.

I have to retain the detent plunger while putting the pivot pin back in.

So I inserted a shorter dowel pin into the block to hold the detent in place, then pressed in the pivot pin which pushed out the shorter pin. The circular groove is from someone using stock screws that were too long...

I decided to remove the front sight. If anyone has a spare Meteor rear sight I'd love it. But I'll just scope the thing for now. I think it would be better with open sights.

Once the small roll pin is pushed out the blade comes loose and the base can be removed.

Somewhat complex. The front plastic pin in the base goes into a hole in the barrel...

I then sanded the stock. I didn't want to put too much effort into it but did want to remove the worst dings and make a good base for refinishing.

It's not a bad piece of wood.

I mounted the stock to a steel bar.

I gave it one light coat of cherry stain.

In between coats of oil I made a muzzle brake...

I decided to go with a minimal brake.

Some very light grooves so my hand could grab it.

The setscrew goes into the hole at the front of the barrel that the front sight registered in. It is a push fit and the setscrew keeps it from coming off.

A coat of primer...

Making the screw cups.

I didn't make them a tight fit as I didn't want to stress the wood. It was pretty thin and already had the one glued split.

I did give them some cold blue. Notice the different heights due to different counterbore depths. I retapped the stock screw threads to 10-32 and used socket head cap screws.

Back together. I think the wood cleaned up nicely. I did 5 coats of Tru-Oil, sanding with a maroon pad. Not perfect but much nicer than it was.

Still a few dings left, didn't want to substantially change the stock.

The finished rifle with a yard sale scope and some rings I hate.

Looks better? It is shooting at about 445 fps w/14.3 gr. pellets, which seems correct. A light and fun little rifle.

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...
