    I found some stainless steel wire cupp brushes on ebay that fit my 4" grinder with 5/8" shaft. They were fairly reasonable, under $10 each. It makes quick work of cleaning aluminum for welding. I was having a heck of a vtime finding them locally.

    using that all your doing is smearing the oxide layer into the aluminum not really removing it

    Sorry for being such a noob but what is the recommended way of removing the oxide layer (and other gunk) from aluminum. Gosh, my shopping list is growing by the minute ....
    Is it OK to want to break something just so that you can weld it back together?

    stainless wire brush by hand
    or Nitric acid with hydrofloric acid but most stay away from the acids cause there dangerous but i use them all the time but also have the proper training to handle them

    I'll need to keep my eye out for sales on stainless wire brushes. Thanks for the tip. I'll pass on the acids ....

    I found out why you shouldn't wear shorts while using a crimped wire wheel on the grinder...I looked like a pin cushion!
    I'll try a crimped one next time.

    I was doing some grinding while wearing shorts quite a while back. Was a bit careless and .... was lucky I didn't sever anything important. Needed stitches though. From that point forward, no shorts while working with power tools. Heck, I try to ensure I wear pants and my steel toe boots when mowing the lawn now ....

    Just think, if you weren't wearing protective gear, you could have been all fashionable with a piercing.

    At that point, why bother with the ER, just hit the tattoo shop.

    Full hand tool assortment, collecting sheet metal hammers/dollies, more time than money.
