Man that is one ugly fork. The fork I'm considering for this experiment is an old vitus alum blades/steel steerer that I thought was a good match to an old sv980 frame.
The stem is steel, and the small section of threaded steerer from another fork.
I wish I could change the title to this thread because I think it has caused some confusion. Just to be clear, there is no gluing of steerer tube to steerer tube. The stem still fully inserts into the fork. It may be a stupid idea for a variety of known and not yet known reasons, but with the setup I am imagining on this paricular bike with a low stem, if the glue fails I don't think I'll have much nore than a very loos headset. Bad, but probably not disasterous even at some speed.
And to an earlier post about alignment, the idea was to set it up in such a way that the bearings would hopefully keep it aligned while the glue hardened. There is a bit of slop in there and it seems like epoxy might work ok, jb weld is all I've heard of.
