Thread: Loading buffer wheels

Sorry if this question has been asked and answered ad nauseum, but I've not found quite what I'm looking for in the archives. So here goes...
I recently was given a harbor freight 8" buffer/grinder as a gift and finally decided to take it for a spin. I notice when trying to load the wheels with any compound- greaseless or otherwise- I only get about half of the wheel covered with compound. Tried different wheels/sizes/compounds/raking again, all with the same half coverage result.
My buffing chops are nonexistent so any help is much appreciated.

When you say you get half the wheel covered do you mean like it blotches or like a coated spot and then non then coated?

Things work best for me when loading greaseless if I kinda lightly push the bar into the wheel for a few seconds and let it heat up, then turn the buffer off and jam the compound into the wheel while its slowing down. I need to do that several times, sometimes.

I get about half the wheel( give or take )coated nice and even then the other half is bald. Tried pulsing motor on and off to load and also trying to load at speed then applying more pressure against the wheel to slow it. Same result.

Scratching my head.

What kind of buff is it???? not brand but stiffness???

Sisal, Sewn, or loose????? what buff are you trying to load with greaseless???

For the greaseless I'm using 4" spiral sewn wheels. Same thing happened applying rouge to a 6" loose cotton buff.


Thanks

If I remember, that is a 3600 rpm buffer. I think you hit the nail on the head when you said lightly touching. I find on that speed buffer that multiple light touching of the compound to the wheel works best. You might also try toggling the on/off switch as you apply the compound lightly (sounds like you are trying this, but with pressure). Less compound is better. You really want a thin coating and not try to cake the compound on the wheel.

Have fun,

Sometimes with a new wheel/buff I end up going through several iterations of loading then then raking. I will load the wheel then rake, then do it again until I get it the way I want it. Sometimes it takes me 3 or 4 times. After the first time they seem work/load good from then on.

Thanks for the tips. I'll keep at it. Just a little frustrating at the moment. As I said my knowledge of greaseless compound is nilch, but the same thing happening with rouge and other bars that I've worked with before threw me for a loop.


Thanks

Keep in mind that different bars are either greasier or dryer too. This makes a difference. The greasy ones tend to be easy to load up and the drier ones take to the toggling. Charlie makes a great point on using the rake too. I rake my wheels often.

Have fun,
