Lugers With Ground-off Stock Lugs Data Request

TIG welding is shielded inert gas atmosphere welding...using a tungsten electrode...pretty much any good welding shop can do it for you...Mating the two parts together so everything is in the right place is the trick...Might be a good idea to make a jig to hold them...

This part of the grip frame is a non-stress area. It should work out fine.

How would you go about the welding and what kind of rod would you use to make sure that you get a uniform finish when you blue it? I have tried different types of welding, but it always shows some degree of "ghosting" in the finish.

Same here, but my mythical lug-less Luger is a shooter, so it would not matter (to me)...And even if it did matter, it wouldn't matter if it mattered...

As for rod, I'm thinking 1/16" 4140 ANNEALED ROUND ROD...I'd cut the two frames in the same two places, then bevel the cuts...I'd hand brush the cut & beveled surfaces with a [new] stainless steel brush to remove any rust/scale/contaminant, make up a jig to hold the pieces in place, use a Miller Shopmaster 300 TIG welder with water-cooled torch and foot rheostat, and put enough weld on the joints to machine away until I get the desired contours...On my cheap Chinese 3in1 mill...

...Or maybe if I'm lazy, just grab a coat hanger and weld it up with that...(That's more likely)...

Edit: Since this is a non-critical area, you could mill the cuts flat and silver-solder or braze the lug section to the grip frame...Silver-solder will take some bluing...Only a light line will show...

Well, that's an approach I have used on some projects as well. It would still be very interesting to know if it's possible to get a nice finish on welded parts. I have managed to get some pretty good results on the weld itself, but there's always a dark halo around the perimeter. Would pre-heating help?

alanint,
Boy that sure clears up things, thx.
I did think, if you wanted, one could still use the Snail Drum even if it might be a little heavier holding without the shoulder stock.
