I like that the blower has tons of CFM, but I also need it to throttle down periodically to about 1/2 of the minimum CFM. Holding my hand over the end is pretty darn hard, given the distance to the end of the tube. I tried to fit several plastic jars I have in my shop but none is quite the right dimension. I'd like to find something snug that I can slip over the end of the tube(I'll cut an opening to a size that will reduce blower CFM to my needs). I don't need to leave it on long enough to overheat the motor, if that could even be an issue.
