I used Stainless Steel Hex Socket Screwsavailable at the hardware store. Put one in my drill and filed the sides down to fit the front socket of the 1901 sight. Quite handsome - I am not trying to fool anybody that I have an all-original piece. Used a small MAPP-Oxygen torch to solder an original front sight base on using silver solder and a jig from Brownells and following their simple instructions (layer of solder on barrel, layer of solder on base, cool, put together and heat) - it took every bit of skill I had and I have been fiddling with that torch for 25 years. As far as melting the armory solder - good luck - I think the steel would melt first! I sacrificed the donor barrel's tip and cut underneath the base and filed the solder off (the barrel was a drilled-out mess). Good luck!
