but yeah seriosuly it wouldnt be difficult to make either of those on a lathe just get the right measurements and do that shit, then you can say you made the whole frame yourself and didnt have to buy shit from some company because you couldnt be arsed to figure out how to do it yourself...
I am building a bmx frame and i dont know how to make a bottom bracket tube or the headtube. What would be the inside diameter of the headtube or bottom bracket. this is all going to be done on a metal lathe. any help is greatly appreciated
