Its a belt driven one Walter, the motor draws within an amp of full rated current with no load,
Checked on the inline duct fans, the performance isn't too impressive. Found one site that listed losses with runs of ducting. Think I move more air when I break wind than they would through 30 or 40 feet of pipe.
So back to the original plan and go with the blower. Made up a couple of transitions (don't laugh at my feeble attempt at sheet metal work) to go to 6 inch duct, which I found at the dump.![[Image: IMG_1738.jpg]](https://lh3.googleusercontent.com/-JC-sYjfLTWI/VVpy4Dg_P4I/AAAAAAAADEI/ST85I-Es9UE/s1280/IMG_1738.jpg)
Used the plasma table to cut them out. Need to tune the motors I guess. With a 40 amp nozzle it wanted 320 inches per minute cut speed. Rounded the corners quite a bit, probably added a 1/4 inch radius as it tried to accelerate. Didn't take long to cut though.

Free advice is worth exactly what you payed for it.
