Re: pic: 1771 finished

The vac is really sweet, did you use a single or two stage? and where did you get the impeller assembly? In the aim high game we built two assemblies, one that used two FP motors and one that used a Cim, we had to juggle the gearing to keep the current draw below what the breakers would hold for a match. As I recall it was about 50 amps. We got more vacume with the single cim, but it tended to take the breaker sooner. We got two stage impellers from a surplus place for not very much money. We also shot for about 25 to 30 K RPM at the impeller. Sorry you are done for the season.
