I'm about to start on my first frame. It's gonna be a pretty basic lugged frame. The plan is to use a 1 1/8" headtube though, which means i will have to TIG/Fillet the joints as there are no lugs. The problem is that i'm using a hobby torch, the Rothenberger Super Fire 2 with MAPP gas. http://www.wilstar.co.uk/productimag...157f57474c.jpgSS-image-2011-02-08-4d5157f57474c.jpg.
I'm doing this in my tiny apartment shed so i can't use a big acetylene/oxy torch. Got to start somewhere..
Will the MAPP gas be hot enough to heat the brass enough to lay fillets? The rest of the frame will be lugged with silver which i reckon the MAPP will do pretty well.
