Amazon has a reasonably priced tool.

Divide by half...find center

Make a simple one like this.

You guys are going to laugh for days when I tell you how I did it. I went to the hardware store and bought a carpenter's chalk snap line. Hooked the loose end on the muzzle, stretched the string back to the breech, eyeballed center on the top flat, gave the line a snap, and I had my line.

Its easy, put the breech plug in. Lay the barrel on a flat surface with the tang down (I use my table saw table) Place a three corner file under the barrel were you want to locate the sight. Drag barrel across file while keeping the tang in contact with flat surface.This will give you a perfect line indexed to the center of the breech plug tang. I hope this makes sense, quicker to do than to type all this out.

Good idea! I like a drill press with a small drill, line it up on the center of the muzzle and mark the muzzle crown. Then transfer it back with a straight-edge.

Thanks you just kickstarted my brain cells
Thanks

If the rear sight is in and you have a drill press then set the drill vice jaws so the barrel will sit on top of them then set the drill halfway between the jaws.
Then sit the barrel on top. use a spirit level to get the back sight level and voila the drill is perpendicular to the back sight and as the barrel will sit between the jaws equally then the drill is along its central axis.

Hi,
You can also use a small flat file as well. The flat file will leave a line mark at center, which allows you to orient the sight nicely.

Clamp it properly, run a small diameter drill bit or small, stiff wire in the drill press at medium speed. Bring it down on the barrel slowly and it will deflect in the direction you need to move until - it doesn’t. That is where you mark, punch, or center drill. The barrel has to be perfectly vertically oriented before you do this.

The triangle file method is fool proof and takes just a few seconds, it is the only method I use.

You can see the marked line;

Seems that some folks want to overy complicate this. Listen to the builders, they have the solution.

 

[Col. Batguano]

The simplest solutions are the best. Unfortunately, I usually have to go through all sorts of complicated iterations before I discover the simple!

I’ve used the file method forever. Only difference I used a flat file instead of a triangle. Both work. BJH

Basically the same thing for me. Piece of string.
