tachyon track bike handlebar setup

Certainly we all remember this thing:


I was thinking about trying to recreate this configuration on my own bike. I figure I can cut off the end of an old steel quill stem, weld it to the crown of an old fork, and mount bullhorns on it. Would really suck if the weld failed while in use, but whatever. thoughts?

no guts, no glory. err, also possibly more skin left on your face though. Just kidding, I bet you'd be fine. Could be sweet looking on the right frame.

For the win.

OP: If you are starting a project like this, why not do it good and proper? Get two steel tubes, have them bent to the right shape, and have someone weld them to the fork legs. There was the guy who wants to bend his own bars at work... get him to make them for you, or chop up some steel bars. Maybe you could use parts of moustache bars or some other crazy bars. Some of those things bend all over the place and are pretty damn long; there's gotta be a suitable bit on one of them. If you know a good welder or someone from BF offers to do it for beers, it won't even be expensive. Plus you'd be my hero.

How can you tell how good the weld is from that pic? I know nothing about this sorta stuff, just asking... I would just torque the **** out of it by hand before riding it to see if it holds.

Props for going ahead with the project.
But it makes me cringe to see how badly scraped up that nice Ritchey bar is. WTF did you do to it? Put it in a 25,4 stem that has sharp edges? That huge gash on the left side looks like it could even be a structural problem. Bars are people, too!!!

Did that, but it really is a supercrappy weld, so I don't know. I can TIG it next week, so if there's any sign of trouble I'll be doing that.

oh yeah, and the bars are scratched up from trying to get brake levers with shrimpy clamps on. only the anodizing is messed up.

Make sure your dental insurance premiums are paid in full, maybe even six months in advance.
Wouldn't it have been easier to use a threadless setup and just move the stem to the bottom of the steer tube?

Maybe it is just me, but conceptually I think this would be a really bad idea. I don't think you could ever get enough tension between the headset, stem and fork to remove any excess play. You will more then likely destroy your headtube or at least mess it up enough to cause other problems if you want to switch this out later down the road.

You would have to put on an extra clamp (half a thrashed stem?) on the top to keep everything together. Plus I dunno how you'd put on the fork crown race.
That setup would be weird and silly. This is weird, silly and cool.

Yea, I could see how welding would be much simpler.

fork crown race goes over the threadless stem (star nut at the top keeps it in place well enough). grill remains intact.

this setup might be a bit easier. build or find a fork with one inch round, non-butted blades and a flat crown. drill out the tops of the crown. add two stems and voila.
