Im wanting to mod my BSA 20 and a few other bikes.
Ive got an ARC welder.
Im going to try to mount brake studs to the chainstays.
The bikes I have are all normal plain steel.
I was gonna cut up old MTBs to get the studs off them. Maybe cut the studs and part of the frame including the bridge and then welding all of that onto the inside of the chainstays.
I got a new packet of 1.6mm arc welding rods. But have been trying to join scrap bike tubes together. No luck. Theres plenty of orange glow on both sides of the metal. But when they cool, it falls apart.
I sanded the metal to shiny bare finish. And I profiled the tubes to fit snuggly together. I cleaned the terminals on the machine and made sure the earth is getting a good firm hold. I managed to get a tube to bridge a set of chainstays. But when I clean up the weld its a bunch of round lumps. Not a line of weld.
Do I have to set the machine up to a different power?
Do I have to move the rod at a different speed?
Do I need thicker welding rods?
Or do I need to get a mig welder?
Ive been thinking of getting a mig. But they are a fair bit of money
