Gap between pan and barrel - powder leaks
« on: November 30, 2015, 11:10:08 AM »
I am hoping I can get some advice on a problem I have where the pan powder falls between the pan and the barrel. It appears to be about a .017" gap and I am trying to figure out the best way for me to fix it.
  I have given thought to using a shim or using JB weld. I have also thought about using leather like a gasket.
  What are your thoughts on this and the best way to handle the problem? I haven't had the lock apart, so I don't know if it needs some more inletting done.
Thanks!

Yes, you need to inlet it.  I saw a friend's gun with the same issue.  He had flame coming out of the trigger guard from the powder that had leaked into the lock mortise.  

Get some inlet black and scrape the wood down.  It should fit sung up to the barrel when you finish.

I had the same problem on one of mine and did just that, it worked great.

Don't scrape the wood down until you determine that is really the problem. I've seen several guns where too much wood was removed from the bottom of the lock mortise causing the lock to cant in at the bottom. You may have to build it back up. You can glue in a sliver of wood or use JB Weld or epoxy and just re-inlet the lock.

i had that same gap issue with a friend's cheap traditions kentucky flinter. after pulling the lock, i made a small 1/4" wide scraper from a broken off piece of single edged razor blade cya glued into a slot in a 1/4" x 3" oak dowel and carefully scraped the TOP part of the lock mortise first, and kept checking the progress by simply refitting the lock back into the mortise.  once the lock/pan was flush to the barrel, only a little bit of scraping was needed for the lower part of the lock mortise.   :bl th up

You can put a square on the top flat of your barrel and see if you lock plate goes in straight as you inlet it deeper. If you have any lock malfunction after you close the gap you can black the lock internals and see if anything is rubbing.
