SRSG questions

I'm trying to build a SRSG for my next coil and I've got a few 
questions. I've found from others examples that I need an 1800 or 
3600 RPM synchronous motor. I called our local motor store and they 
assured me they had a 1/3 hp 1800 RPM synchronous motor. I went to go 
buy this motor and found that the stamp on the casing says 1725 
RPM's. The sales person said it was a synchronous motor built with an 
outer coil with spinning bars on the inside as opposed to the 2 coil 
system, so it appears he knows what he's talking about. My question 
is could I use this motor for a SRSG? My next question is what is G10 
and where can I get it? Apparently everyone uses it for their disc 
but I've never even heard of it. Finally, I noticed the recent post 
on power arcing of SRSG's but I don't know what power arcing is. 
Could someone explain please? As always I appreciate the help.
