Sannino frame cracked...fixable?
1 Attachment(s)
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?http://bikeforums.net/attachment.php...hmentid=220709

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... http://www.bikeforums.net/showthread...-amp-Framesets |
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.

-Kurt http://www.os2.dhs.org/~john/commuter/06.jpg 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. |
^^....20 years down the road when that frame shows up in a "can you ID this ancient frame" thread people will be scratching their heads!

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.

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... http://www.mytenspeeds.com/My_TenSpe...ont_Left_1.jpg |

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.
