Sam,

You know, I used to think about doing that back in the early 70's. At the time adhesive technology required that the gap between tube and lug be quite consistant. I never got past that particular requirement before I got distracted and ended not thinking about doing that until now. Provide the GOO and I'll stick an "experimental" frame together. I think we'll use a standard brazed fork until I see how tough the frame is. The only problem I see is that if a joint fails it is likely to be a catastrosphic failier. That might be a bit "dangerous". Gentle testing at first, not to exceed 80 mph on the downhills ;-)!

I'm game. Lets do it. I think brazeing the dropouts at first also.

Brian Baylis La Mesa, CA I've brazed my fingers together several times; this could be even easier to stick the fingers together.
