Do you use a different wheel for each grit of polishing? Or do you just clean the wheel after each grit and apply the next grade of rouge/compound?

Thanks

Good question.
There are different grits just as there are different types of buffs (or wheels).
It is hard to change a wheel everytime you need to change grit. I have different machines set up with different types of wheels for each purpose and grit.From grinders, to wire wheels, to hard and soft buffs, they all serve a purpose.
That is why I have so many machines from the pawn shops, they are cheep and plentiful.
I'm not saying you need to run out and purchase a bunch of machines so you can buff.
Most machines can hold two tools, one on each end.
A set up of a hard and soft wheel used together can be useful.
Clean the wheels between grits, then change to the other wheel when a soft touch is needed.
The softer the wheel, the more dangerous it becomes in my opinion. It makes you want to push harder and then takes your work away from you if you are not really careful. It is THE most dangerous tool in my shop, and I don't likle to buff.
When it is time for me to buff, I approach it very soberly.
It can change your life in a second.

I say that the buffer is the most dangerous thing in my shop because it is the only machine that wants to take a knife away and throw it back at me.

Often the buffs pick up grit from other machines producing dust. It is always smart to clean your buffs before you start, between grits, and cover them with a plastic bag when not in use.
Hope it helps. :)
