Information wanted on pinning a 10/22 bolt

[Rifleman44]

Hi guys:

I'd like to do the bolt pinning mod and get the hole in the right spot.
Rimfire Central has a post with some hints but no dimensions.

a) Can anyone point me to a drawing or sketch that shows where to drill the hole?
b) Failing that, if somebody has a precision aftermarket firing pin not yet installed, I'd appreciate a measurement of its height near the firing end.


Thanks

I can take pictures of mine. I have measured everything except the hole depth.
I've had a few beers and I'm using a standard Vern.

Hole center is .100 from the top of the Bolt and .237 from the Bolt face.
The Hole is .09375(3/32).
my Pin is a #42 Drill Rod that's .330 long.
The Hole is about .025 deeper than the Pins length.

One of My Pins end is cut on an Angle so, That's as close as my Verns get.

Let me know if you want anymore detailed Pics

This is a RT Bolt.

what I want to know is how you get thru all those case hardened surfaces?

HaHa, no thanks.
That looks like a problem waiting to happen.

Maybe... but if Chaser is recommending it, then it works.

This is a RT Bolt.

RT bolts are reworked factory bolts.

My findings are about the same as Innercity except the pin is placed a little more center in the upper bolt face wall.

 

[Innercity]

Yeah that one is way more centered. and it's staked too.

That Digimatic looks pretty old, I don't remember when they came out with the first one but I've never seen one that colour.

lol....I got them brand new in the late 80's
They've seen a lot of miles and just keep on ticking.
Good luck with the project.....
