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........

Brad

(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.

thanks guys............don't have one of those rpm guns, I'll use the
400 rpm change per click and make sure I don't burn the gel-
coat...................HANK..............you know how hard I've
struggled to get a nice looking gelcoat...........BURN
IT!.................no way...........
