i used cold gun blue to patina my new ground up. i'm super pleased with how it turned out. it barely tinted the brass and silver braze, so the lugs are outlined and the fillets really stand out. it's definitely fragile though. it can scratch fairly easy. it's pretty much only going to see racing, so i'm not going to bother clearcoating it or waxing it... i'm going to let it get worn and look used. the gun blue is probably only a stopgap until i get it powdercoated after this season anyways. it's super easy to do and touches up easily too.
i'm happy with the build. eric let me do most of the non-torch work. it was super fun. it came out fairly lighter than i thought, for a huge, stiff, steel frame. it's like 6.5 pounds, but built up seems lighter than my bianchi. it's mainly columbus sp and an spx downtube. true temper bmx stays. they're super stiff!!! i used some old cinelli road lugs and some no-name italian bb shell that eric gave me on my wedding. i carved a heart out into every lug. awwww. eric had to cut off the chainstay lugs, due to the angle, and fillet brazed them to the shell.
the build up is still not quite right. i still need to get my track pedals and 50t chainring on, and i think swap the headset. it's one of those weird star ones that didn't have the original bearings, and the .125 ones i used are too big. i could only fit 33 and it's supposed to have 38. also, the weird foam rubber gaskets are super flat... i'll probably just get a campy one. i also thought about trying liquid gasket to try repairing the rubber gasket/brass shim seal setup.
i can't wait to get in on the track!
