I don’t fully understand what you’re trying to accomplish (what’s a unicycle leg?), but if you’re going to have a bearing in your assembly, the balls will need raceways through which to travel. The raceways (there must be two) are the structures which handle all the stresses and strains between the axle and the frame.
If you weld a raceway of a size used in most unicycles, chances are you’d deform the raceway and ruin any chance of making a decent bearing. If the welding doesn’t deform the raceway, the frame most likely will. You’d need to make some custom outer raceways that look like the lollipop-style bearing holders in order to accomodate the strains induced by riding.
The more secretive you are, the less help the community can give you. If you really want help with your design, you need to disclose your plans!
By raceway do you mean a bearing part or what holds a bearing? If you mean what holds a bearing like in the picture I dont think a little distortion will hurt its holding abilaties.
Brian could you use an old frame and just use a leg off of there or that might be to short or just not what you’re looking for?
Note: you dont have to answer why you wouldn’t want to use it if it lets out your secret.
You can change a tire while still in the forks…that’s pretty cool! (bikes get many more flats than uni’s) They are alos more durable as they use roller bearings and square tubing, something that would be way too heavy if done on both sides
I think my best option will be to just weld the bearing caps of normal unicycles and weld them to the end, as I did in my 2 wheeler project, that did not deform them at all.
I was kinda hoping not to do this, as I am going to need 6 of them
By unicycle leg, I meant one side from under the crown to the bearing bolts

He is talking about what some people call “races” the innermost ring that is pressed onto the axle, is the inner race. and what your bearing housings clamp onto is the outer race. If you where to pull the casings or dust guards off (most bearings wont let you pull them off without deystroying them) you would see that on the inner side of the races is a highly polished round track. I you where to weld (or put any type of extreme heat) on the outer race, it would warp the race and the bearing would turn to shit.
My friend had a cannondale lefty fork, and said that it was horrible. He said that the weight distribution was pretty uneven and he couldn’t stand it.
