Early Crosman Model 101 Resealing, Part 4

Now to make the new exhaust valve seal...

I decided that Delrin would be a good choice for the valve seal material since the old seal seemed to be made of hard plastic.


I ground a sharp tool with lots of positive rake and a flat face, set it to the proper angle with an angle gage.

One cut.

The other.

Parted off, compared to the old seal.

The exhaust valve reassembled. You can see my precision drawing underneath.
