The Paterak framebuilding book recommended this as a way to keep chatter down. It doesn''t hurt, not sure if it helps. The sleeve reinforces the thin tubing (.5mm at that portion) where the seatpost slot is and keeps it from distorting too much during brazing. There are a minimum of three brazing operations there (top tube, seat stays, and binder). Early TIG welded bicycles also used a sleeve, newer ones usually use externally butted tubing that is larger diameter there than in the thin section. Lugged bicycles have a lug which does the same job. Jimmy — the blob of silly putty is silly putty (actually it is plumbing putty).

We''ll see how I do in that department on the rear triangle. Jerry — More flux is a message that I got on the framebuilders list too. We”ll see how I do in that department on the rear triangle.

Your miters(copes?) and fillets look great. Tip: If you flux 3-4" down the tubes you don''t get the heat discoloration, making clean-up a little easier. Keep it up, you''ll have a rideable frame before you know it! Jerry Nice work Alex! Your miters(copes?) and fillets look great.

Tip: If you flux 3-4″ down the tubes you don”t get the heat discoloration, making clean-up a little easier.

Keep it up, you”ll have a rideable frame before you know it!
