Hey all - I've done lots of productive wrenching on this pistol (Norinco M93 Sportsman), but this one has me stumped. The ejector has worked its way a bit loose, so I'd like to remove it and tighten up the fitment. But the ejector pin seems overly tight for its size, and I've broken one punch on it already...

Anyone have any tips on how to get the ejector pin out? It's 1/16", and recessed in the slide grooves on the frame. I'm not even sure which direction it's supposed to go, or if it can go either way. I've managed to get it moving about 3/32" in either direction, but no more.

If it matters, and if you're not familiar with the model, it is a surprisingly faithful (but rough) copy of the Colt pre-war Woodsman.

Any input is appreciated, thanks in advance.

I suspect "rough enough" that parts don't interchange. :( A press ?

Grizz
 
I've found on stubborn pins that a starter punch works best. Take your broken 1/16 and shorten the shank to about 3/16. Easier to use blunt force trauma on this one without bending and breakage.

Yep. Been there done that! In a different context. (punching Cherry-Lock, and Cherry-Max rivets to remove them)

Use a cordless drill to turn the broken punch down while grinding it. You can make the diameter you need, about any length you want, feeding the rotating broke off punch against the grindstone. You can even make a really nice radius if you want.
 
Thanks guys - Good idea to make a starter punch with the busted tool. I don't think there is quite 3/16" of the business end left, unfortunately.

Is heat going to help at all for something like this?

Any idea if the pin is directional? All other pins on these pistols have been ambi.
 
Not likely that there are staking striations on the pins themselves but who knows what those communist bastards do to continually ruin your day...
I wouldn't think you could isolate heat small enough to make a difference without having the heat flow to other areas. Try modifying your busted tool as suggested by Trevj, then have at it with a bigger hammer. Light strikes aren't going to do much.

I would chime in to say that a small hammer moving fast makes for a sharp blow on the punch, where a big hammer moving slow, tends to 'push' the whole assembly, if that seems to make sense.

I liked using a smaller hammer and had real good results with that tactic.

Sorta along the same lines as applying XX number of foot pounds energy (Same number of Ft/Lbs in either case) using a BP cartridge and big heavy bullet, or a varmint gun and a very fast, light one. The result should be the same if math is all you go by, but the results on target can vary widely!

In any case, it's a good place to make sure you are as solid and square on the pin as possible, you have your gun blocked up so it is well supported (Hockey pucks work great) and you are in a comfortable state of mind with the set-up, as that makes it less like that you will screw up! :)
 
Does anyone have parts for the m-93? I need a firing pin and spring. Does anyone know if the pre-woodsman firing pin and spring will work in the Norinco?

Marstar lists the firing pin spring in stock, but not the pin itself. They are pretty awesome at responding to customer emails, and who knows, they may have a firing pin in the back somewhere
