Tig welding aluminum in the DMV ?

[n18]

First, TIG welding requires that you remove the paint(such as by using Acetone), and clean the surface as much as possible. I would try independent auto repair shops, but there is not much money they can make from you. You could get a torch($58) from Home Depot and aluminum brazing rod($5, but you might need several), and weld it yourself as shown in the following videos, but I don’t know if it would be strong enough. A new frame might be a better option.

There are few ads in Craig’s List for TIG welding:

Bruce the Welder, welds in his garage in Falls Church, just off the WOD near mile marker 6.5. Use to advertise on CL. I had him weld both CroMoly frame & Ti derailleur

Bruce rocks. I have his contact info if anyone wants to private message me for it.

longest seat tube that gets you to the right height plus glue (epoxy)? If there’s enough tube in the frame I’d guess the force on that little bit at the top shouldn’t matter much–it’s mostly there to be the clamp to keep the tube from sinking downward. If you clamp that tight to the seat tube, then glue it and the seat tube to the rest of the frame, you’d mostly be trying to counteract the rotational forces and I’d think there’d be enough bonded surface to do that. You’d just never be able to adjust the seat height ever again. On the up side, you could really mess with bike seat thieves.
