Trigger / scope hammer fix
« on: January 20, 2005, 04:13:59 PM »
Has anybody tried heating this hammer and bending it to get it away from the scope instead of adding that hammer spur?

I've done this on a Hawkin BP gun and it was pretty easy on that.

I was think'n about giving this a little "crick" in it's neck and thought I'd see if anybody had tried it.

Some have ground the hammer spur down to give some clearance, but keep in mind that any mods to the hammer will void the factory warranty.

the only way to get the clearance FIXED to a good height is go to the old models,without the transfer bar.....it gets you about a quarter in. lower....but it doesVOILD THE WARRANTY......JB

Why would you have to grind any thing?

You could pull the hammer out and heat that spur to  bend it anyway you want. Of course taking it apart yourself at technicly voids the whole warranty but I don't see how seperating the hammer from the gun. Heating it by it's self and reinstalling it could have any detrimental effects on the rest of the gun that replacing the hammer with a new one couldn't fix.

I was just worried about the geometry, if you bent it straight back, making it overly difficult to pull. In the full reverse direction there is still a half inch of travel you could use to pull it away from the scope.

I'd rather bend it about 30 - 40 degrees to the right, instead of straight back. This would put the material essentially in the same position as the spur with out adding any mass  to the hammer.

If nobody else has done it. I'm deffinately going to try it.

If I need it, how long does it take to get a replacement and what do they cost? $5 maybe?

Those that have done trigger jobs have said the triggers were returned to "normal" when they sent the frame in for a new barrel, FWIW. But if they shortened the trigger spring, I could see H&R putting things back to normal, but I didn't shorten any springs on the last 3 that I've done and I still have triggers that weight between 2.3 and 2.6lbs using a Lyman Digital trigger scale. As for the hammer, Brownell's charges $9.11 for the hammer assembly. I thought about buying and extra and cross drilling it to lighten it!  :wink:

This thought just came to me... don't have my handi handy  :grin: to check and see what it looks like, exactly, but.... how about taking the spur extension off, drill a small hole, like 1/8 inch or so thru the hammer and insterting an aluminum rod thru the hole to act as a spur.  Sure would be lighter.

If you going to heat the hammer spur you want to make sure no heat gets to the hammer sear it would ruin the trigger pull for sure. The hammer is heat treated to withstand the hammer fall on the transfer bar and frame. If that steel got soft by heating the anvil would flatten out and wreak the firing pin projection.

A 1/8" threaded steel pin would work, aluminum would cause electrolysis and start corrosion. The pin would have to be removable so you can remove the hammer which comes out through the bottom.

I think you could reduce the weight of the extension by putting it into the lath and machine it down some. It don't need to be that fat and wide.

Jack: Tried it once, it seems their hammers and triggers are some kind of powder steel technology. When I heated it and tried to bend it down it cracked, I did set it down some when I welded the spur back on. If you do have luck with this, gives us the lowdown. Another thought is that someone once point out that they hammers for the rifles and shotguns are different, but I'm not sure how.  Good Luck: :grin: <>< Duce:

Did you heat that till it was red before bending?

Did you try to use any type of heat sink to keep the rest cool? At least clamp everything else in a vise and then bend?

Did you use acetalyne? It will heat faster and there fore heat the rest of the part less.

I'm thinking of clamping the rest in a vise with a lead guard. This will protect from deformation and also act as an early warning if the sear is getting hot.

I think I'll cool it down with compressed air so as not to make it brittle and still cool quickly once the bend is made.

Still thinking it over so far. Thanks for the warnings and tips. It helps to know what to watch out for.

Did any of that damage the heat treating of the sear? I can't imagine an acetylene torch on the spur getting more heat to the sear than this did?
