    I've converted one side of my bench grinder for a polishing wheel but have run into something I didn't expect so am asking. I'm new to polishing sp have a lot to learn. Problem I'm having is the "wheel" a open, unsewn sisal throws off a LOT of threads even just applying the green polishing compound. It shreds some but not quite as bad when you're actually using it. Are all un-sewn wheels like this or is this another Harbor Freight mistake I've made. As it is I'll have to make a box almost completely enclosing the back and sides of the wheel just to make it bearable. Thanks for any help.

    Yeah, those kinds of wheels aren't worth a damn and I've wondered how they can be passed as polishing wheels at all.

    You want the other more solid cotton type - the one that costs more. They'll load up with polish without throwing anything off and can last for years with only scraping/cleaning maintenance..

    With Harbor Freight, you take your chances. I haven't used HF wheels and I haven't ever had cause to complain about the wheels I get from Brownell's, but I have always used such a box as you describe to contain the throw-off.

    That is why I never buy my polishing wheels or grinder stuff from "China Freight"
    I would hate for them to mess up my work of they really failed.

    there are different thread counts and different stiching the more rings of stiching the stiffer the wheel / faster the cut within each compund.
    the un stiched or open are for buffing /final stages, my set-up has four wheels
    and then a buffing wheel , but I only use one rouge or compound per wheel.
    Buy American

    The only time my open unsewn wheel would fray is when I use the rake to clean it. I store all my buffing wheels in a special cabinet that keeps the contamination down and clean. Not good having it exposed next to a grinder.

    btw. What speed is your buffer motor running at? 3450 or 1700. I have never run my 8" wheels on a high speed motor.
