Hammer extension question

[alnitak]

I replaced the rebounding hammer in my 94AE, However, the new hammer doesn't have the hole to screw in a hammer extension. Does anyone know what drill and tap I would need to use to add the appropriate hole for a hammer extension?

Get one that jus uses a set screw. What Win hammer has a hole in it ?

Later AE rifles have the hole. I have one and the first time I noticed the hole I thought termites had been at it.

Try Uncle Mikes. that's what the factory uses for their Handi Rifles these days.

I've seen the Uncle Mike's that add on with a set screw. I've also read concerns about that set up holding, even with locktite on the screw.

Still, it's probably a better choice than me attempting to drill/tap and buggering up the hammer.

I would get the Uncle Mikes, and with the post by Tycer on the various types of loctite, you can choose what to use to keep the set screw from backing out.

FWIW, I've used set-screw type offset hammer spurs for many years, w/o one loosening even a bit - until I did it myself for removal.

If you're going to be taking the rifle completely apart - removing the hammer, etc - very often, then I suppose the threads could wear (the offset spurs are aluminum) enough so the setscrew wouldn't hold it's tightness.

If you know someone who has a tap and die set, there is usually a gauge in the kit you can use to measure the threads. Or, if you have a screw assortment you can see what will screw into the hole on the old hammer. You got my curiosity up and I just tried that with my Pachmayr gunsmith screw assortment. The smallest screw in that is a 6-48 F and it's too big.

Good luck. I don't blame you for wanting to tap it instead of using a slip over. I use a slip over on my Encore and like it since it extends out both sides and the angle I shoot from sometimes changes which side of the scope my thumb comes up on.

Good to know. And it certainly is the easier route.

Put a little piece of tape on the hammer.
Slip the extension on to just where you want it.
Check to make sure the positioning of the extension is correct.
Recheck the positioning of the extension and then check everything again.
Screw the set screw in to where the tape is clearly marked (marred).
Remove the hammer extension.
Position the rifle to where the hammer is securely backed with steel, such as a small steel block.
Use a center punch to tap the hammer right on top of the mar in the tape.
Make a small indentation in your hammer with the center punch.
Remove the tape. Re-install the extension, check alignment on everything.
Put a drop of blue loctite on the screw and tighten everything up.
This should hold ya for many years.

That hammer has a hardening to it, you might get a drill through it, I doubt the tap would survive.

Good to know...typically I find these things out after I mess up the job!

Clever, BC! I like it and can see where that would "lock in" the screw.
