   At 50amps, code requires 8/2 WG or 8/3 WG...About $100 per 50 feet. And   
   yes, 8 guage wire is very hard to work with. OTH, you could get by with   
   using 12/3 WG on 220v at 30amps and 50 feet would only cost you $30...

   I share those two appliances on the dryer's 220v line. Not a problem as   
   the dryer isn't using enough amps to stop the compressor from running at   
   the same time. I don't leave the compressor on unless I'm using it and the   
   wife knows not to start the dryer when the compressor is running.

   You would have to go back to the breaker box and make sure that the two   
   110v hot lines you use for 220v are from opposite sides of the box with a   
   return to the ground buss.
