Friends:  I am just about finished with the touch-up painting on the Jack Taylor fillet brazed touring bicycle I purchased about a month ago.   I have fortunately found a near-exact paint match ant it seems to take well to the frame.  I will, however be searching for a fork to match and the attendant racks and other accoutrement's that would fully outfit the bike.       Since inspecting the bike I notice that unlike many other bikes of differing and of the same make, it lacks the vent holes of so many others.  The vent holes were to allow the gasses of the brazing process to escape and not create a bomb within the confined spaces of tubes under heat with a brazing torch.  This seems to inject an unknown factor in the unseen tube areas (seat and chain stays in particular) and some of the main tubes as well.     As I have inspected the seat tube, it ends at the BB shell in a semicircular fashion with two rusty crescents that butt against the Seat tube on the interior.  After treating with one of my favorite products, Evapo-Rust, these two areas were well cleaned.   What my question boils down to is if I (or the frame) would be better served if I bored vent holes for the TT and the ST from the BB shell and then treated the interior of the tubes with an appropriate rust inhibitor.   I await the tried experience of the many.      BT
