My electrician did not know (had never needed to do this before)and suggested trying it to the ground first and, if it didn't work, rewire it to the Neutral. I want to do it correctly so please help me here.

If "your electrician" does knot know get a different electrician. He does not know what he is doing visa-a-vi the current code.
We had 3 wire 220 for ever. Neutral is ground. Then someone decided that we needed 4 wire. Neutral and ground. The thing is that the neutral and ground wire are tied together in the breaker box. So what is the difference? There will be all sorts of explanations that will try to make a case but we existed for many many years with 3 wire 220 voltage in our houses without a problem. Your electric stove and dryer for example.
My understanding is that IF you took 110V off the remote location they did not want the return current going down the uninstalled ground wire in a 3 wire instillation even though it was reasonably insulated. Hence the 4 wire cable with the neutral wire insulated.
Just wire it neutral to neutral and ground to ground.
Btw, my 2009 Powermatic 3HP table saw is 220V and is only 3 wire.
the only thing that will plug into the 230 outlet. Then if you need to hook it up to 120 use the patch cable that you made for the shopsmith cord 
.
so you are less likely 
to destroy 120 devices by inadvertently attaching it to 230.
