What would make a good motor for a rotary gap? I was thinking of a 3/4hp,
1725rpm. Would this work? I found one but it is $100.00 and i am not willing to
pay that much. What would be the lowest i could go with the HP and the RPM? i
am planing to make this gap (http://fp2.antelecom-dot-net/brianb/rsg.htm). Where
could i buy a motor for this gap? Also, where can I get a peice of LE Phenolic
disk 1/2" thick and 9" in diameter?
Thanks
