M-16 Style Extractor question

[SuperiorRifles]

Doing my first M-16 style extractor install for a friend, this will be a standard bolt face. My question is about soldering the filler ring into the bolt. This seems a bit concerning, do to the fact that the bolt head is brazed onto the bolt body. I am to use a 95/5 silver solder? But the solder just beads up and will not go between the ring to adhere it to the bolt nose. I don't want to get the bolt head too hot to melt the brazing on the bolt head. Would using a JB weld or steel epoxy work for this application? If not, any soldering tips?

For soldering try tinning the insert first, then align the CLEAN, fluxed parts, clamp and heat the assembly up. Brownells as a silver bearing solder than runs at around 450 degrees that should work and not affect the factory brazed joint.
The guy that taught me barreling used JB weld and never had one come loose.
The main thing with either method is the surfaces to be joined must be clean.

That was what I was hoping to hear. JB weld!! Got to love it! I use it on installing bolt sleeves and it works great. Plus the ring isn't taking any abuse from recoil or anything really. I bet the most pressure it will see is from the milling machine when the extractor cut is made. Any other ideas or concerns I might not be thinking about before I use the JB Weld?

If you have a blast cabinet, I would lightly "dust" the surfaces to be joined, and clean them thororoughly with something like MEK or brake cleaner to give the epoxy a good grip.

Thanks Kendog!!

If your solder is beading up, you have the metal to hot.... there is a real fine line to getting the temps just right. JB will not be a problem..

Try some of Brownell's Force-44, great stuff and lower heat needed.

Thanks for all of the tips. Went with the JB weld and it worked great.

My experience with soldering: machine it to fit, clean it, flux it, heat it until solder melts, the flux will draw the solder into the joint. then clean up and machine the extractor slot and drill the pin hole.

The brownells, silver solder and flux has worked well every time I have used it. a propane torch reaches 1000 degrees heat paste helps protect the rest of the bolt.
