-mostly need an axle size we pretty much have a machine shop so we can fabricate almost anything anything helps!
Lefty hubs are made specifically for the Lefty mono-fork. Or non-fork I guess. What's a fork with only one tine? A spear?
Easiest is to just go order one from a Cannondale dealer. $$$$ not cheap though.
The Lefty's are built tough enough for MTB riding, but do you really need that much strength?
One way people who build home-made tadpole trikes (two wheels in front) is they use a 20" BMX wheel and adjust the axle so it sticks all out of one side. You can do this because with those wheels, the axle is just a long piece of threaded rod. .....There's two different front BMX axles common--one is like 3/8" thick and the other is 9/16" or 5/8" maybe. If you get a BMX wheel with the thicker axle, it's strong enough to support a few dozen pounds that way. These wheels only cost $40 or so each, and it's complete, it's not just a hub. Putting brakes on the rear (non-turning) wheels is easier.
Because you have access to machine tools--if you really thought that you needed something stronger than a BMX wheel hub, then it would probably cheapest to just make your own front hubs.
