New Vent Hole Liner

[UtahFlintlock]

I thought the members here would appreciate this. I own a Homer Dangler JP Beck style rifle that my father and I built for me back in 1993-94. After I got back into shooting this year, I noticed the vent hole had gotten pretty big. A machinist friend helped me replace the old vent hole liner with one from Jim Chambers. The new liner makes a world of difference. Much faster ignition than the old brass one. I took it to my local club shoot a few weeks ago, and honestly have never been able to shoot consistently as well as I had. Before, the ignition had been pretty finicky.

A good stainless liner like the Chambers will last as long as the rifle and give super reliability with ignition.

The back of the pan needs to be a good tight fit up against the barrel flat or you will blow fouling down into the lock. I can see how the flat as been filed to flush out the liner but it may have produced a gap that will need to be closed. Probably inletting the lock plate a bit farther and perhap some bolster filing to close any gap that may have appeared.

No gap is present in the final product, and when I shot it after the work, and subsequently cleaned it, no fouling worked its way inside.

My friend used an end mill to cut down most of the vent hole liner, and then a few passes with a file to make it smooth. It mainly took the browning off, which was already worn in that area.
