ken98k Posted March 28, 2009 Report Share Posted March 28, 2009 Has anyone ever soldered on square bridges? I got this blank square bridge set off ebay a few monthe ago and now I'm getting ready to start on the rifle where I'll use them. I'm not exactly sure how to solder them on. I figured I would first tin the parts to be soldered, then clamp them together and place them in an oven for 20 minutes or so. Link to comment Share on other sites More sharing options...
tinkerfive Posted March 28, 2009 Report Share Posted March 28, 2009 I've been soldering crap for many years. Tin yes. Oven NOOOOOoooooo. You don't want to anneal the receiver. Do it in one series of steps. Lets say you start with the bridge till you get the hang of it. Tin the base, set it down, tin the bridge, immediately place the still hot base on the bridge and reheat till you're sure that the solder on both the bridge and base have become one. Repeat the above steps on the ring. I assume that you know to flux. Tinker Link to comment Share on other sites More sharing options...

(I do this every day) I occasionaly solder wires with a small soldering iron. But I'm more than a little apprehensive about using a torch on a receiver. I figured that I could regulate the temp of an oven to the melting point of the solder. Link to comment Share on other sites More sharing options...
Vladymere Posted March 29, 2009 Report Share Posted March 29, 2009 Solder it just like the copper pipes you do. Tin both pieces, apply flux, assemble parts, heat until solder will wick into the seam of the assembled parts. That is the traditional method for applying sights annd such to Mausers and how I attached the rear mount, front "saddle" mount and express sight to the sporterized Kar.98a rifle below. Vlad Five shot group off the bench at 100 yards with the rifle above. Link to comment Share on other sites More sharing options...
