You drill a hole through both walls of both chainstays and then insert a tube. I've never seen an example of this type of construction, but Tim Paterek describes it in his framebuilding manual (p. 3-16). Dear Gary, You may be right, but the hole would put the bridge awfully close to the bottom bracket. I'm not sure if the two uncaptioned pictures are of the same frame or of different frames. If they're the same frame (?), the first picture shows a chainstay bridge in place and much further from the bottom bracket than the hole in the chainstay in the second picture. Whatever's going on, it's a good example of how a little explanation and some better pictures would clear things up. Cheers, Carl Fogel |

I think that's the seatstay bridge in the first photo, not the chainstay bridge. It doesn't look like it's drilled for a brake, so maybe this is a track bike -- in which case it wouldn't surprise me if the bike had very short chainstays (and a bridge very close to the bottom bracket). Whatever's going on, it's a good example of how a little explanation and some better pictures would clear things up. Agreed. |

Water-out hole in the wrong place?
In article b312db5c-646c-4fd6-957b-f7aec7020e94
@s8g2000prg.googlegroups.com, says... Well, more pictures, but I don't know about explaining: http://tinyurl.com/26svgq Yes, explanations there, too -- it does specify an open CS bridge and open tube ends -- most builders either dome the tube ends or fill them with spelter, but it's not really necessary if the joints are done well, and it does save fractions of an ounce of filler. -- is Joshua Putnam http://www.phred.org/~josh/ Braze your own bicycle frames.

That's the bridge -- just imagine driving a straight piece of tubing through both chainstays, cutting the ends flush with the outside walls of the chainstays, and then brazing it in place. It's like a tunnel through the chainstays. Because of the presence of the tube, the chainstays themselves are just as much sealed as on an ordinary frame. (The seatstays are a different matter, and are probably open at both ends.) Maybe a very curved chainstay bridge went in through the hole?

Cheers, Carl Fogel Dear Gary, You may be right. I can't tell if that's the inside of a piece of bridge tubing or just the far wall of the chainstay: http://i24.ebayimg.com/08/i/000/cc/df/bc7c_12.JPG As for the curving, it looks to me as if the bridge piece in the chainstay (if there is one--that's how unsure I am) has to be a curved shape to end up so far forward from the hole (if it's going through the hole): http://i12.ebayimg.com/02/i/000/cc/df/b112_12.JPG But now I wonder if maybe the camera angle is deceiving me. Frustratingly, we could tell for sure in a second or two if we had the actual bike. If I had to bet at this point, I'd bet on your explanation. Cheers, Carl Fogel |
