On a lugged frame, the lug shorelines should be even and the torch heat used to draw the brazing material into the joint so that there is good filler penetration without voids. The lug points should be thinned with a file to prevent stress risers from hard spots. Cleanup involves filing excess filler material off of the tubing and the lug, and not leaving any file marks.
On chrome plated frames and polished stainless steel frames, any imperfections stand out like a sore thumb. Here is an example of lug brazing very close to perfection. Dave Wages (Ellis Cycles) was the brazer of this Waterford 953 frame before hanging out his own shingle.
