I may try to braze the parts. If brazing does not work and the parts are not ruined, I will buy a welder and try welding it, after practicing on scrap.

Thanks for all the help!

Many years ago I had a similar setup with a hub into a sprocket. A local machinest / handy guy silver soldered it together and it ran a small hydraulic pump for years with no problems. Just a thought. :geek: I had not considered silver solder. Because of the high shear stress the bond will be subje...

Practicing on similar sized scrap may be a challenge. I don't know exactly what these parts are made of. I think I can get some thin and thick steel plate to practice on.

Thanks for your input.

Be aware, the collar appears to be zinc plated and that will play a bit of havoc with welding (TIG). The trick with welding differing thicknesses is to focus the majority of heat on the thicker piece, then whip over to the thinner side. If there is zinc plating would this cause problems with flux c...

If the 2parts will thread back together leaving little chance of mis alignment then I think the easiest would be an autogenous Tig weld on the thin edged side - putting much heat in on the flat side will likely cause it to warp. The pieces do fit back together so there should be no misalignment. I ...

I am new to welding. A friend of mine asked me to fix his industrial trike. It has a broken "band-brake" which consists of a collar which is threaded into a 1/6" disc. The threads are stripped. I would like weld the collar to the disc. I am looking for advice on how to proceed. Both p...
