A muscle bike build you say kingfish254.. I have a sweet one that I purchased from a fellow bike club member but I do want to build one. Here is my 63 24inch stingray clone. It is a true 63 schwinn that Denis Kamstra did a awesome job building. I fell in love with it the first time I saw it so when he decided to sell it I had to have it..
That 24 inch 'ray is awesome! Great looking klunker you got going too.
Well I put Fred all the way together to do a ride this past weekend and found a little problem. Went for a quick little shake down ride in the neighborhood and kept hearing and feeling a loud pop. Finally found where it was coming from. The braze on the seat tube where it meets the bottom bracket broke. Headed to a club members shop to have him weld it back together for me. Glad I found it before paint....

That's interesting,looks like it wasn't even welded to begin with.I think I'd check the rest of the frame.Well I put Fred all the way together to do a ride this past weekend and found a little problem.

Those frames are brazed not welded.
It was brazed inside the bottom bracket. Can't complain the frame is 50 to 60 years old..
I guess that makes sense,wasn't thinking brazed.
Okay Kevin and Falstaff, here's a good teaching moment for y'all for this country bumpkin' that doesn't know the difference between brazing and welding....?

Brazing is heating the metals and melting bronze or silver into the joint to join them together. Look up fillet brazing. I want to learn some day.
I'm guessing that either form of welding, tig or mig (heh, pretty cool huh, I knew those two words..haha!) is a stronger more industrial type bond than a braze? I'm thinking "braze-ons" like water bottle cage screw mounts etc are not designed to take the stress and leverage a frame might undergo? So, why did they use brazing instead of welding on these particular bike frames?
Yea....
What he said.
My dad taught me when I was about 8 or so, but that's the last time I did it.
I don't think welding technology was very available back then,but brazing is pretty strong. Think of all the 1940's and earlier bicycles that were brazed and are still rollin'
Glad you found it now and not later!

Rat Rod it looks original. When I pull the crank out I will take a couple of pics.. I give the builder's back then nothing but props. A majority of the bikes built nowadays won't be around in 10 years much less 50 or 60.

You should've never brought up the name 'Flunker'!Well I put Fred all the way together to do a ride this past weekend and found a little problem.

Just kidding, glad you found out in time to fix the problem before you finished the build. You might consider welding the other joints also for good measure.
