I know ya been gettin good advice on this problem...But i'm gonna throw my 2 cents in for what its worth...Have ya checked the hand channel for a large burr, or deep tool marking that could be imparing the hand spring?
Yes sir I did. I disassembled completely and went over the channel area and looked for Burrs and rough spots and even foreign objects. I have a nice bench light with a 10" magnifying glass and found nothing that was getting in the way.
The original BP cylinder worked smooth and perfect. But the conversion cylinder just plain locks up.
I am fully expecting to hear that the ratchet on the conversion will need to be stoned or material removed. We'll see in a few weeks.
Thanks for the 2 cents! I appreciate it.
