What touch hole liner do I need to upgrade a Thompson Center flintlock?

[Greg Blackburn]

Hello all!

What size touch hole liner (size and thread) do I need to upgrade a Thompson Center flint lock flash hole to one that is larger and takes a hex wrench? I've bought these before but it's been 8 years.

Thanks!

I think it is 1/4-28 liner that you need.

I use RMC OX-Yoke hex liners in all mine that will accept them. They come pre drilled with a 1/16 touch hole. I like them way better than the liners with the screw driver slot. The screw drive slotted ones seem to collect more fouling.

Track of the Wolf sells a 1/4-28 threaded liner for the TC flintlocks. It is # THL-TCF on the page this link takes you to.

TOTW is a good company to deal with and has an excellent reputation.

If you buy some other 1/4-28 vent liner be prepared to shorten it to match the length of the existing vent liner in your gun.
Vent liners are usually longer than needed and if you install one that's too long it can cause ignition problems.

...and cleaning problems.

I us the RMC OX-Yoke hex liners and I use the flat faced ones for a screwdriver and both work flawlessly.But I run a patch down after every shot and pick the vent hole.

You still see the TC package of two touchhole bushings (item #7327) on the shelves of some stores and shops, though I don’t know if they current item. As Zonie suggested, you may want to shorten them a bit and make sure you have a healthy cone or chamfer on the powder side.

Just leave your existing touch hole alone & drill it out with a #51 bit = .067"

GOT THE RIFLE. It sparks very well, at least in my inexperienced mind. Very clean weapon, touch hole liner came out and looks perfect. I hope to try this rifle out soon, this week or next. Oh wait....need some .45 caliber balls! OK.....order those first then try it out.

I had a Uncle mike’s touch hole on my t/c 45 years ago. Lightning fast and easy to install. Don’t know if it is still available.
