Attaching lugs to BB shells

After having our first tandem custom built, I seem to have developed a bit of a fascination with frame building. Of particular interest is building with bamboo. I know that there are kits out there but having my own stand or 2 of bamboo I have started to mull around what it would take to put together components to build from scratch using my own bamboo.
I have a concept in my head, plenty of experience with carbon and fiberglass fabrication, my own Induma mill and Hendy lathe, ESAB tig/mig/stick welder and plenty of mechanical background to go along. I just have a couple of more things to mull around before I pick up some starter materials.

In looking at framebuilder supply, I have found dropouts that will meet my needs but the shells with lugs might have larger lugs than I would wish to use. If you ever do it, how do you about attaching your own tubing to blank shells? Tig, mig or braze? I would expect braze to not be strong enough but that is why I am asking here.

Thanks
