touchhole

[airbear]

OK, in building my rifle, I don't want a touchhole liner, Im just going to use a hole drilled in the barrel, but should I cone it and if so, from the outside or the inside? Thanks

without a liner, how are you going to cone from the inside? I'd like to know how it could be done, I might learn something. You might use the search bar to see recent posts on this topic, there are quite a few good suggestions and ideas already explored. Good luck, keep us posted.

Airbear,

I personal install a liner so this is not first hand info. I can direct you to better instructions if someone doesn't check in with better instruction.

Some use a small nail, flatening the end to a cutter and then hardening it. You have to install it from the inside sticking the shaft out the hole you have drilled and chuck it up in a drill. Then go to town.

The old timers used a device like this one.

I would rather have a liner, but you can use the "Nock" system. You drill a suitable hole in the side of the barrel opposite the touch hole, cone the hole with a drill bit, or whatever,then thread the access hole and plug it with a threaded shaft. I love PC, but when it comes to vents, I like a liner. From everthing I have read, inside cones in early America are no more PC than a liner, although you can,t see it.

For what it's worth, there are some antique rifles that have had a liner installed. If you're interested in how a touch hole might have been coned, check out The Gunsmith of Grenville County. Mr. Alexander has a fascinating sketch of a gadget which will reach into the breech and, through a series of gears, drive a coning bit into the hole. 50 calibre and larger, i think.

Although it might not be really PC, i don't think anyone will fault you if you make use of technology which might have been available to those of the 17th & 18th centuries.

Heck, just put a "White Litnin'" in the thing. Relax- enjoy- it's supposed to go bang, after all.

I built a Tulle with a liner, then built an English fowler with a touch hole. Why ? just for the heck of it. :: The Chambers lock with just a touch hole is just as fast as the L& R lock with a liner.

Something I came up with a few years ago for internal coning of touchhole.
