frame building/modifying question

I have absolutely no idea but something popped in my head this morning,since i cant find a proper sized vintage road frame for myself.

why not simply debraze (desolder) the tubes from the lugs, shorten them and rebraze ? (its an old 20$ frame btw) I would have my 50 cm seattube and a little shorter top and downtube who would suit me well.

the probleme would be the rear triangle, what to do with it?


anyways my question is , is it doable, would be fun to experiment (i have the oxy acetylene torchs and brass/silver rods already

Thats sort of the way I got into framebuilding, I was watching a cross race and it just came to me that I wanted to build a bike frame. I went straight home and started tearing apart my old Giant ATX 760. I would do it since you have the torch and the frame is only $20. I imagine after you are finished playing with this you will be stoked and go buy some new tubes and lugs and build yourself a complete frame then you'll be hooked. You probably won't even have to mess with the rear triangle unless there is something about it that you don't like. Anyway, have fun.

Yeah, thats quite a bit but if you are gonna debraze the main triangle you might as well remove the seat stays and shorten them as well, they'll need to be remitered more than likely. Sounds like you've got the itch to build a bicycle frame so since you have everything you need you might as well do it.

I don't know if I forgot to hit post, but my previous post isn't here. The rear triangle is the least of your problems. Cut the seat stays from the seat lug and de-braze them from the dropouts. You could also do it the other way around, cut at the dropouts, but you might have to bend them too much to make that work very well.
