Thread: Buffing Compound and Dremels

So I made a Sisal buffing wheel for my Dremel.

I now need some black compound to test it on.

Does anyone have any extra that they can contribute to science?

BTW - If this needs moved please do so.

Are you talking about Emory compound like the Roybi or Dico available at every hardware store????
Or are you talking about the greaseless compounds in actual grit sizes???

BTW I do believe that both of these are rated for no more than 3500 rpm....

3500 rpm on a 6" wheel. It has more to do with surface speed so any dremel speed with a 1.5" wheel should be okay.

Yep Dan is right, math what a concept

That's a lot of heat to be careful of........

I am using 8 inch buff wheels on motors that are 1800 rpm and 1100 rpm and you have to be careful of the heat even at these speeds.

I am gonna shoot for a 1-1/2 wheel and I will stop by and get some Emory compound from the local hardware store.

I can tell you the Ryobi compounds both the white and the black that a dremel at any setting can generate a lot of heat in a hurry. I also find that they will leave streaks. I am looking for different compound because I want to actually complete a perfect mirror finish on a razor at some point.
As for the math, the angular speed of RPM's on a machine is consistent. The only difference is as Dan says, the larger wheel turns faster. For example on a 6" wheel the surface sped at 3500 rpms would be roughly 63k inches/min. On the other hand the the dremel with a 1.5 wheel at 10krpms is a surface speed of roughly 45k inches/min. But, at the high setting of 35krpms the surface speed is 157Kinches/min so make sure you go slow. I ruined a blade polishing with a dremel and it never would hone so I threw it away.
I am no expert like these other guys, but I have ruined a blade by being impatient with a dremel and turning it up full speed. The blade I ruined almost had a true mirror finish, but I still ruined it.
Good Luck
