Rotary pads?

**sparkie** · 12-23-2006, 05:00 PM

Who has these? Do you like them? Would you buy them again? I still don't know what to order! Please help.

I'm getting a rotary for Christmas.

I don't know what to buy!
Guys, yal pick one for me! Help a brother out!

I'l ordering the Waved ones. I'm using the 6"s I have now with my new rotary and love them. Aaron keeps telling that they are the one's to get and I will!

So you can use the 6"s with an rotary.
Thanks man!

Is this it?

Yep. You sure can. The 6s are actually safer because they spin slower than the 8s at the same setting. Physics. Aaron explained it all to me!!!

LOL!

You all have heard of Paul from the UK......the 8k detailer?

Look at about half way through the video. You'll see him using a 6 inch pad with his Makita Rotary.

I'm confused, how does a 6" spin slower? I thought an 8" would?

Is this also true for DA's even though it's a different type of buffer?

the outer edge (extra 2 inches) spins faster, creating more heat.

I've got a couple sets of Edge 2000 pads in both the 6" & 8", all of which are flat. The only convoluted pads I have are from 3M, which I've been using for many years. For my rotary work on most automobiles, I prefer the 6" pads over the 8" pads. For many autos, I find the the 6" pads fit better into more places and contour better on many surfaces. I mainly use the 8" pads on larger vehicles with larger flat surfaces (trucks, trailers, rv's, etc), but find myself reaching for the 6" pads more often than not when working on most cars.

The speed at the outer edge of the pad will always be greater than the speeds inside when the pad is spinning. Simply put, the outside edge travels a farther distance in the same amount of time as the inside, which means its moving at a faster speed. Make sense?

Makes perfect sense. If you placed a mark on the outter edge of a 8" pad and then one at a 6" point, they would be back at the same spot at the same time. The outter HAD to move faster to get back around at the same time.

Remember a DA is oscialating. A smaller pad on a DA will move faster giving more cut.

True, a smaller pad on a DA will definitely move faster, but that only accounts for some of the additional cut. Most of the additional cut is because there's more pressure per square inch being applied with a smaller 4" pad as opposed to a larger 6" pad. In fact, a 6" pad has more than twice the area of a 4" pad!

(A = p r ^2), which means the Area is equal to 3.14 times the Radius Squared. A 4" pad will have an area of about 12.57 in^2 where as a 6" pad will have an area of about 28.27 in^2. An 8" pad has a whopping area of 201.06 in^2, or about 7 times that of a 6" pad and nearly 16 times that of a 4" pad!

Justin, I'm sure you already knew this, but I wanted to post this info for the benefit of others who may not have looked at the pad size from this perspective.
