Early Crosman Model 101 Resealing, Part 5

Now to finish up.

Reassembly is easy. I held back the trigger and inserted upper half of the valve with the transfer port aligned with the barrel.

I inserted a rod (a transfer punch worked well) through the hole in the top of the breech into the transfer port to keep in in alignment as I tightened the valve nut down. Then the rest of the hammer assembly was installed, and the small setscrew on the breech was replaced.

The last thing was the cork gasket between the butt stock and the receiver. I scraped the remnants of the old one from the stock.

Punched a hole in some cork gasket.

Assembled and trimmed the cork with an Xacto knife.

It's a bit thick.

Here's a shot of an old gasket from another rifle. The cork should be squished down to next to nothing at the gap?

After leaving it overnight I removed the gasket and trimmed a bit more around the sides.

Still too thick? I'll leave it for a while and retrim as needed.

The rifle all back together. Notice the chip on the forearm. Character.

I cleaned most of the loose rust from the rear sight and reinstalled it.

So, how does it shoot?
Accuracy is pretty good, I got several groups at 7m from rest that were about 5/8" to 3/4" CTC with three pumps.

Velocity with 6 pumps (the maximum recommended by the period manual) was between 477-503 fps with 14.3 gr. CP pellets.

Nick,
Just came across your Crossman 101 posting. I have my dad's rifle. I remember when I was a kid in the 1950's watching him pick off woodpeckers in our trees. I rebuilt it 6 or 7 years ago. I found the original Crossman tool he had bought, still in the original mailer.
I wonder if parts will be available when it comes time to do it again?
Thanks!

I think there will always be parts, and as I have done, you can always fabricate replacements. One of the nice things about the 101 is that DT Fletcher has a CD available with most of the parts blueprints for the 101 that he got from the Crosman archive.
