You can buy them from Cleaveland tools. http://www.cleavelandtool.com/3M-Cut.../#.W7lIRfZFzIU

I got mine from them as part of a tool kit from Cleaveland. I've used mine a lot in building my RV-10 and it is still going strong. But I've got it mounted on a low speed 1,750 RPM grinder, so that may be a reason for my success with the wheel.

Cheers,

Van's has them for $76.00. Handy if you happen to need other parts from them.

A grinder is too fast for making the scotchbrite last IMHO. I chuck mine in a variable speed standing drill press and so far one has lasted me thru my entire build - year 5.5 now......I dont know what speed its on, but its probably no more than 500-700rpm - not super fast and for sure not even remotely as fast as my grinder......

The high $ 3M wheel will last much longer than he cheaper alternatives. It works better as well.

Also, working the piece across the wheel vs in line with the wheel will prevent grooves from forming. Work across the wheel for rough finishing and then switch to in line with a smooth pass and the parts will look and feel mirror smooth.

Ditto for me and you have better access to it.

Scotchbrite wheels come in many different grades (just like sandpaper and scotchbrite pads)

The rate they wear depends on the one used, and how it is used, and not so much how fast it is turned. The best tool to mount one on is a powered buffer. It has no shield to limit access to the wheel and the shaft is long to move it farther away from the motor and give good access to the wheel.
The cheap one at H.F. hold up just fine for this use.



The wheel we use in our shop is the same one sold in the Van's Accessory catalog. We use it a lot, but it lasts a looooong time (probably a couple years at least).

On Scott's recommendation, I went and bought the HF buffer as shown above. It has held up extremely well and the results using Van's or a 3M wheel are excellent. I now have a deburring wheel on each end of the buffer. One has a round profile on it and the other is flat. I imagine that I could produce two RVs without replacing wheels using this system.

I highly recommend that you purchase a box of dust masks (3M) with the nipple on the end. These are about $2 each but what is your health worth? One of these dust masks lasts for a long time.

You will be amazed at the amount of aluminum 'dust' that appears in your shop unless you use a vacuum at the buffer.
