How to Turn OFF Center

My thanks to all for your ideas

I have no problem now to complete the job
 
Joe Pie has a great video of turning a crankshaft using a emergency collet drilled off center, you could do something similar with a bush in a chuck.

 
Excellent video and ideas but way out of my capabilities man
 
Drill two sets of centres. One as normal and the other clamp your shaft With a v block. Set it up in the mill vertical with stops to repeat clamping position. Calculate your centre offset for your eccentric. Drill your offset centre. Unclamp rotate 180 degrees now drill your second offset centre. Set up with a lathe dog and turn from both sets of centres between centres. One concentric and the other as an eccentric. Accurate and very repeatable with centres.
