Blower size

Hey Flats, I didn't see your post earlier. That may be the better way to go. The shop vac is incredibly noisy and old so probably wouldn't work for long. I'm not much of an electrician so I'll talk to my son (he's the smart one) and see if he can help. I appreciate the idea. Thanks, Ted
