Has anyone found something that fits snugly over the blower tube to reduce CFM?

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.

Dave, the only thing that comes to mind would be reducers for plumbing fittings maybe? Just thinking out loud. I haven't measured the outlet of the blower.

Idea: Since the tube has a gradual taper to it, if you do find a fitting of some sort that is just slightly too large you could trim the tube back to where it DOES fit snug. If this is something you'd want to try, I would contact Ego first and check the price/availability of a replacement tube in case cutting it back has a negative effect on its un-capped performance.

In fact, if a replacement tube is within your budget you may want to have two tubes; one for all out blowing and one with a reduced permanently adhered to it. The 530cfm blower tube is very easy to remove, so that might be an attractive option.

Be careful not to restrict it too much... these turbine fan blowers don't work well with highly restricted openings. Some experimenting will be necessary to get it right, I'd think. :-)
