I am in the process of clearing stuff out and figured I would post these here before I throw them out. I have seen some designs that used a vacuum cleaner motor for the spark gap of a tesla coil. Without the filters in front of these, the motors move a tremendous amount of air. They also heat the air quite a bit. I have a bunch of vacuum cleaner motors that I have removed from vacuum cleaners. All these units were picked up off the curbside. I suspect most of them work, but have not tested them. As you can see, most are in OK shape with a few that are ugly. The big ones are about 12 amps, the little ones are around 9 amps. Also pictured are the rubber 'boots' that fit on one side of the motor. $25 + shipping takes the whole lot. I'm in Austin, TX. If you're interested let me know your address and I will get you a shipping estimate. http://imgur.com/a/J8omT Eric _______________________________________________ Tesla mailing list Tesla@xxxxxxxxxx http://www.pupman.com/mailman/listinfo/tesla
