There's an outfit in Louisiana, ad in SSM, that may use spray weld on hooks. I spoke to 'em a few years ago about tightening an SS for me. The owner wouldn't say what welding process they used so I didn't go that route. I don't think it's unreasonable to ask what method of repair will be used on a very expensive gun and expect an answer. In the event, I fired up the lathe, made a new hinge pin and rejointed the action. Better and cheaper solution but way more time consuming.

The outfit in LA told me they do a series of welds that gradually builds up the hook and then it is fitted precisely. They also said the cost is in the $700 neighborhood. Not a job for inexpensive guns.

Plasma spray was the original term for what is being called a 'sprayed on weld' here, useful for rebuilding crank pins on locomotive crankshafts and other applications that involve very expensive parts being repaired to original dimensions, and in some cases to better than original, from a duribility perspective. The equipment is not inexpensive and like most forms of precision work requires expertise for best results. As in welding, a broad selection of materials is available for use with this method. I would strongly suspect the work is being subcontracted out for any gun related repairs, but would have no reason to think the end result would not be satisfactory.

Here is a good link on the subject:

Send it to Freddie Brunner in the L.A. area.....he is a master TIG welder. He recently put the tip back on an old L.C. Smith 10 gauge cocking rod....you could not see where the work had been done....truly a craftsman. He is routinely used by Walt Schiessl the L.C. Smith man who swears by Freddie.
