About the first thing I do is take a hacksaw and cut a bunch of it off, so it looks something like the photo below. Having it tapered to the rear also reduces the likelihood of taking a chip out when removing the barrel. No use inletting any more than you have to either. Many originals I have examined have the same treatment. The barrel in the picture is from #42 RCA. Regards, TC

It's mighty hard to inlet a straight sided lug and get a tight fit.  So, Viewed from the rear, the tang is filed to the barrel flat width and the lug below is sawed or filed into a flat bottomed "V" shape.  Draft is filed into the tang sides and rear.  Much better inleting now..............................Lynn

Unless its just the photo, that sure is a tiny vent...

Scott, The one thing I would add in addition to what folks have already told you, including the detailed description of the process Rich gave you when you posted this question last week, is that when it comes to putting a slight draft on all of the parts that get inlet, don't overdo it. The more draft you put on it the more difficult the job becomes. More is not better you need just s very slight amount. Roundball, the vent size looks about right to me. Maybe its just because I examined it in person so I know its the correct size. Regards, TC

Is the 42 vent coned on the inside?

I like the notch for the lock bolt, as a hole causes the breech wood to crack if someone forgets to take the lockbolt out first.

Acer, I don't know if it has an internal cone or not. Unbreeching the barrel is about the only thing Wallace didn't do at the 2007 WKU seminar.

Ok, I'll be the wiseguy and ask- How big U like 'em


A #51 drill bout right!   5/64 th gettin close to losing 2 f to the outside - 3/32 time to replace the thingee! As an aside pick the vent as little as possible and do not use a roughened pick for obvious reasons.

Hey Roger, Yes #51 or there abouts. Another thing about the breech I showed in my pic,,, just my personal opinion but it took me about 2seconds when I first saw it to decide that its rebushed. Not because it isn't greatly enlarged or anything, it just looks like there is a bushing in there to me. Not something I've ever heard anyone else mention, and I sure don't want anyone to think I'm trying to degrade the gun in any way, or if that even would... just my opinion. Regards, TC

On first impression, I too thought it had a bushing.  May just be the light or the photo...........................Lynn
