I have a problem with a Webley Senior piston. The holding face where the sear engages is worn and rounded, probably due to cocking link wear a long time ago.

ive got 2 ideas for a "fix" and would appreciate views about how to go about it.

(1) get the front of the piston machined down and then fit a new front end , holding ring and head onto it.
I think the problem with this is how much "meat" is behind the holding ring---IE- how deep the piston is drilled for the mainspring.

(2) Get the ring welded up and then cleaned up. Is this possible? Use Mig or Tig?


Im hoping Edbear might see the "Edbear signal"
