Re: Tinsmith's in frame gas tank for cantilever Schwinn.
i use a torch, and a big yellow Mapp gas one at that. it's not exactly the ideal tool for the job, but it's all i've got.
i plan on buying a nice heavy duty soldering iron one of these days, and then move on to a welder.
you guys are doing an awesome how-to here, keep up the good work!
