Scotch Brite Tool

[tboyett]

Has anyone tried one of the Harbor Freight 4inch Abrasive Balls for scuffing aluminum prior to priming/surface treatment?

You can find it here: http://www.harborfreight.com/4-inch-180-grit-medium-grade-abrasive-ball-96945.html

The picture looks like 7447 Scotch Brite.

Thanks,
Tom

I use a regular green scotchbrite by hand. I use the HB flat ones in a die grinder to clean up edges of aluminum after cutting.

What's HB?

Paul,

What do you mean by HB?

Thanks,
Tom

I threw together my own. Works well with a light touch for scuffing tank rivet lines for proseal but I haven't found much use other than that.

Harbor Freight, or you can get them from Grainger.

Please be careful. That ball thingy is only rated at 5K rpm. It might come apart on you if your not careful.
You can scuff down a panel by hand in short order with the pads. I only use the disks when I am dealing with pretty serious corrossion issues, or as one technique for edge breaking as mentioned.

Thanks

Larry, nice picture of your adaptation. Thanks.

Jonjay, I was thinking about using with an electric screwdriver for that very reason. I appreciate your warning.

Best,
Tom
