Can you or know someone who can chuck it up in a lathe or a mill? That would be your best bet, you can use a dial indicator, to get perfectly on center. If you are a about 1/16 off center I doubt there will be material left to get it to run true. Did you use a hand drill, if so even if you started on center I doubt that you were able to hold the drill perfectly strait all the way through(no one could)
As much as I hate to say it, unfortunately you may have to get a new hub & have a machinist drill or bore it.

I had the same thought as to what he meant ... he's actually trying to get a sprocket/rotor carrier hub plate drilled with the sprocket/rotor holes correctly centered.

Thanks guys
I ordered two more hubs with the correct bolt pattern.I will use the others for spares but I am still trying to figure out the BEST way to redrill the old hubs.I noticed in Ckau's mod for his axle he used the same hub from BMI.My plan now is to place new and old hubs over one inch axle then use center punch from harber frieght (just found out about these punches) to mark new holes Thanks again Tim Last edited by tim; 05-16-2012 at 12:32 PM. |
