math problem-slightly OT

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.

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...........

Cheers,
Brad

Hey Brad, I don't think Hank was implying that you burn the whole
thing, and then turn it down.

Surely you must have a test part that you could use? Maybe Dan could
loan you his cirrus horizontal for a weekend.

Turn it up till it burns gelcoat- then slow down.
That's how everybody does it.

Police said it was one of those cases best left unsolved!
