Karl, if I buy a blasting cabinet, I'll be looking for a new wife. I have managed to fill our basement, which is finished and important living space for us, with 914 parts. I think the last straw was a few nights ago, when my wife went into the closet to pull out the ironing board only to have a full set of rusty, greasy engine tins land on her unshod feet.
