View Full Version : Hub Alignment Jig

Just an excuse to play with my lathe really.

I turned up some home cast aluminium and bored a hole to match the axle, then ran a tap through the side for a bolt. It only needs to be finger tight.

Much easier than the tackweld and hammer method.

If you could get some kind of electrical isolation at the chuck, then a slow turn would also allow you to do a full 360 degree robotic quality weld.
Maybe a nylon sleeve placed over the axle in the chuck. The Ground clamp would then sit just behind the hub flange.

Wow, Brad! Too complex! :D

Plus, I suspect that with the state of my tack welding skills, a hammer is going to be needed...

Hi Blaxmyth,
today I have just done something similar. needed a square face to a threaded rod so threaded the plate screwed it on and used a back nut to seat it the welded it and true it in the lathe to face it up using bored jaws, in the case of what your doing its only finess as its the rim that needs to be true.
having said that. I think you just love using your lathe and good for you, if you have the tools use them and enjoy
