I found this old Roadmaster in the basement and decided it might be a good frame to hack apart and use for a swing bike project. Holy Smokes Batman check these welds! They almost seem to defy logic. I know I'm ignorant about some things, maybe even more things than I know, but something is just not right here. It's obvious the bike was though some abuse, and yet has not come apart. Maybe the logic here is, it can't come apart, if it was never together to begin with.
Yes, that's a Wear your helmut safety sticker . . . Gee Why? Is it because the welds are below the surface of the tube? Does the tube even touch the head tube? Did a team of hampsters wel this thing together from the inside out?
What? . . . Why waste time mitering tubes together? This is what was revealed to me when I hacked the downtube off. That hole is the bottom of the seat tube.
Now time for a picture of some quality at Benetti's.
Well here it is so far. That's a fork steerer sweated into a piece of 1-1/8" 4130, brazed to the seat tube. Nothing fancy. Brazing together old tubing is not fun. It's hard enough to clean new tubing, let alone painted, rusted tubing.
