So I finally decided to try my hand at making leather seals.
As I related before, the seals on the Predom worked ok, but were really nasty looking.
So I turned up a form from some UHMW scrap.
And pressed a piece of wet leather in, leaving it clamped for 24 hours.
Then I trimmed away the excess.
I finished up with a very sharp xacto.
Doesn't look bad.
I made the inner washer by stamping with an arch punch.
Then punching the hole. I knew all my leatherworking tools would come in handy someday.
Exciting!
Old and new seals.
I soaked them in oil for 24 hours.
The inner leather washer had to have the countersink for the screw head. I basically just carved it out with the xacto before soaking..
It sort of wiggled around a bit when I screwed down the screw, but I was able to massage it back round. I inserted it into the pistol and reassembled.
Well, it hasn't made any difference in velocity, although I'm hoping as it wears in it will become more efficient. We'll see. I had a hard time deciding between hair out and hair in, but the original seal seemed to have the hairy side out, so that's what I went with.

Nick,
Cardew did some tests and said rough side faces out. So, I'll put you down as on his side.
