Rotary and smaller sections/panels

Give it a try on a test panel...use a 4" pad and a 6.5" pad, hold it in one spot for a certain amount of time and see how hot each one gets. The 4" will probably burn thru and be VERY hot.

sorry ...but your wrong

on a rotary 1000 RPM = 1000 RPM the force does not change the # of rotations
also the outer edge will spin about 1/2 as fast @ any given RPM then a 8" pad
less speed = less heat

you should not get confused. Rotary is a "big" tool that delivers 1000rpm=1000rpm. PC is a "small" tool it has not the power to get a 8inch pad up to work correctly so smaller pads seem to work more efficiently.

I do full corrections with 5.5" and 4" pads on a Makita rotary.

If I induce any holograms, I take them right out with another pass of polish. I am starting to prefer the 4" over anything else.

What brand of 4" pads do you like the best?

BigJim is right. Think back to high school/college physics. The period of one revolution is the same for each pad, no matter the pad diameter. Lets say one pad has twice the radius of another pad. The smaller pad will have half the tangental velocity of the larger pad. That is what we are concerned with in this situation, tangental velocity.

Tangental velocity. Is that what you get when you've had too much to drink?
