  • Using Greaseless Comppunds

    I started playing around with some greaseless compounds in order to sand some aluminum welds after grinding them down.
    I used the 80 grit with a 4" wheel on a variable speed hand grinder. I applied the compound and then allowed it to dry before using. What I found was that the compound sat on the surface of the wheel only, when I used it I didn't get a lot done before I had to reapply more compound. I found that lower speeds worked better. I had expected it to last longer. Is this typical

    yes it is .... you can hold the compound longer with time ... i get around 15 to 20 min on my compound ... i load it and wait a few sec's then get to sanding ....

      So how do you extend the time, are you saying that as you use the wheel more, more compound will saturate the wheel and extend the time.

        from what i have found the compound work's in to the wheel ... the more you load it ... i still got 80 grit on a wheel and i have not use it in a few days ... i willl be pulling it out friday i got a few thing's to sand ....

          I've found slower speeds on the wheels make greaseless last a bit longer. I'm not talking RPMs, but surface speeds. If I use 6" wheels with greasless, I get maybe 5 minutes of working time before it's time to reload. If I use 4" wheels, I get about 15 mins out of 'em.

          RPM in both cases is 3450, but the smaller circumference of the 4" wheels get the surface speed down quite a bit. 5419 SFPM for a 6" wheel, 3612 SFPM for the 4" wheels. That's about an 1800 SFPM difference.

          Also, pushing too hard or catching an edge will reduce the work time with greaseless compounds as well.
