Chapter #3 in the story of the unknown frame: Damaged seat tube + die grinder = ready for thee framebuilder to braze in a new tube:
Yes, yes - I know the seat lug didn't come out too well:
The little tool that made it possible:
just get a really long seat post: think how much lighter it will be!
I vote for PVC pipe...
no no no.. carbon fiber!
I may have missed an earlier posting about this...
what frame is it that is worth doing that?
hope it is something really special...
or did you do it just because you can?
Irregardless is not a word, and you do not sound more intelligent using it.
hey that works for me...
Hmmm...interesting. So just slide the new tube in through the seat lug into the bottom bracket shell, a bit of JB Weld, and voila! a new frame!

A broom stick might work, and also give you an integrated seat post.
Oh - one more thing:

Is that tool air powered?
I guess you just attacked from the top grinding the tube away, and for the BB just chop the tube close to the bottom and grind the rest out?
It ain't right unless you curved (I know there's gotta be a proper term) the bottom of the tube inside the BB shell.
The correct term is mitered, and any good frame builder should have no problem doing that.
I know miters as straight cuts, like when I install carpentry moldings. On a bike like what would be used on DT the at the head lug. Does the term apply to the rounded forms?
the real question is what to do about paint.
I suggest just putting a clearcoat over the thing as is, with the raw seat tube. The frame has an interesting legacy, and the paint job should reflect that, and look cool at the same time.
That, and all second-gen Paramounts had their seat tube mitered to the downtube.
I'm thinking deep metallic blue (or emerald green) with gold lining in the future - but in the meantime, it's going to be double orange with oxide red.
