Thanks all!
I've got the lugged steel itch bad.
I've been out whacking a no-good frame up for brazing practice. I don't want to screw up the downtube shifter bosses and waterbottle bosses on my old Fuji (not a ding or rust spot on the frame).
Of course, my ultimate goal is to going to braze and build a touring bike, paint it and then ride off somewhere next summer.
