ok, I'm pretty math challenged....so here goes......I'm about ready to
start power cutting/buffing my HP-24 horiz stabilizer..............the
RPM range for my power buffer is 1000 to 3000 rpm. the rotary knob on
the power buffer is numbered from 1 to 6.

I am pretty sure that number 1 would be 1000 rpm and number 6 would be
3000 rpm. the rubbing compound and the polishing compounds require
specific rpm settings.............sooooooooo.........

my question is what rpm settings would I get from numbers 2 thru 5?

and don't tell me that I my Harbor Fraud power buffer is the
problem........

(3000-1000)/(6-1) = 400 RPM increments, assuming that it is a linear
scale.

1 - 1000
2 - 1400
3 - 1800
4 - 2200
5 - 2600
6 - 3000

do you have one of those guns that people use to determine the RPM of
their propellers or fan blades or anything else that spins? Might be
able to get it to read the RPM of your buffer to make sure that the
knob is in fact a linear scale.
