Indian & Harley frames were furnaced brazed for a long time,
but,
I think they did have the odd plug weld.

I dont think brazing a frame has any strength issues if they are slip fit joints, then brazed.

On vintage bicycle frames they are often brazed which leaves a nice clean joint, and they hold up very well.. I probably could show a dozen examples tha are 50 years old if you come to visit..

Oh and St Pattie is a burger.. not the Irish dude..kghost..

Hate to dissapont but ALL the old Brits were Brazed BUT most tube joints were "socketed" (tube inside a hole) not but jointed

Until this evening, I hadn't brazed anything in ages....

Sandblasted the heck out of my header and found one little pinhole a few inches ahead of the collector. The mig would probably just make the hole bigger. GAG!!! No O2 in the tank, either. Found that a propane plumber's torch would get the area bright red - enough to melt a puddle of silver brazing wire on there. As long as the pipe doesn't get red-hot that far down, it should stay there ok. I hope.


As for seat and tank mounts, I'd weld them. Tank repairs? That's something else entirely.

....thank god for modern day welding technology and Miller Electrics.

The Lincoln aint bad either. ;)


Happy trails.

Thanks guys and yes I was talking about oxyacetylene. I have a real nice set up that I use for building bicycles. I have ordered some high tensile rod. This is going to be the first bike I build and not just motor and one thing I have learned from years of doing it wrong is ask someone that knows first.
