Thanks for the info-Completed repair last night
Thanks for all the info. I never realized there was so much history in the replica world.
The problem is was having was that the bolt would retract and then pop up before it reach half cock.
I solve this by ever so slightly bending the hammer side of bolt fork toward the hammer. This added tension and kept the bolt engaged with hammer as it went to half cock.
Let me know it this sounds correct.
With all the internet help on how to tune a Pietta, I was able to figure this out.
I work as a Biomedical Engineer (Medical Equipment), but I'm not a paper pusher, I work with my hands.
Once again, thanks for all of the responses.
PS. It is a .36 cal, I measured it.
