Sannino frame cracked...fixable?

I see a nice frame in my size on ebay. It has a crack in the bottom bracket between the seat tube and down tube (in the lug). Beautiful otherwise. Do you think I could get someone to do a repair or should I just be more patient for a nice 52 or 53 cm frame?

Crack in the bb shell would scare me away. Lots of heat required to replace the shell.

PM irvri and buy either the Superbe or the Peugeot frameset...

Cracked bottom bracket shell - I suggest you move on. This area carries the highest forces, I doubt welding it would work. Even if you find someone to replace the shell, requires re-brazing 4 tubes and a repaint.

Likely overheated when built in the first place - you'll only add more problems if you have the BB swapped out - or even if you fillet it.

When my commuter bike was stolen in Madison many years ago, I dragged out the old Italian frame a friend had given me. No idea who the maker was, but it was pretty decent with Campy dropouts, chrome socks, Prugnant lugs, etc. He had gotten it second hand many years before and road it all over the place, including the cross-continental Bikecentennial route in 1976. A couple years later, the bottom bracket failed in the manner the OP's BB failed, so he gave me the frame. It languished in my closet until my commuter bike was stolen, so then I decided to make it my new commuter bike. Off came the old BB, and on went a new one:



That was in 1987. 20-some odd years later, it's still going strong.

YMMV, it's not an easy job and likely to be prohibitively expensive unless you do the work yourself like I did.

But it's not necessarily a lost cause.

Man, I am impressed you could do that. I'm not quite there yet, though when I retire, I hope to learn more about frame building.

OK, in light of the new information, I would like to change my answer. Just put some JB Weld on it

I had the same situation several years ago, before I really knew all that much about vintage bicycles. The fellow who owned the bike told me he noticed a small crack, rebrazed or silver soldered the crack, allowing for a bit of a build up of brazing material. Filed or sanded it smooth, slapped on some paint and let it go at that.

I never had a problem with the bottom bracket and, with a little more cleaning and smoothing, the repair became all but invisible...

Nice!

"Bilaminate" bottom bracket!

the original bike is probably made with brass, so that repair is doable even though the frame might want to have a bag over its head when it goes out to a nice restaurant

A lot of really good info in this thread. I wrecked my bike recently and have been worried that the frame has been compromised and I can't see it.

that was my bike, lost with others to a loan shark, I rode it as it was, bike was crashed many times and heavly abused, the crack appeared about 100 miles after the seat stays were re-attached the frame was straightened earlier on, the seat stays were probably stressed most when I pulled a 200 lb trailer from Spokane to Snoqualmie Pass in December '88, the forks are "new", it is a 54 cm I had planned to drill holes in each end of the crack to keep it form getting bigger, a frame builder friend advised not to replace or braze it, I bought another Sannino to replace this one, I later rebuilt and repainted it for a spare and sentiments as it still rode well
