I've posted a couple of photos of a diesel shell that I recently
subjected to air honing with Aluminum Oxide.

use it. If you don't I'd encourage you to get one because they are quite
useful. Or make one. I like Jack's idea. I've used a cardboard box!

Actually, there are 2 good reasons not to use Al Oxide. Both have
already been mentioned. The first is that it is a significant
inhalation hazard. I find the idea of using a cardboard box to contain
it SCARY! When I used it in my grit blaster there was always some small
leakage and that's a much tighter box. If you use Al Oxide, use a well
fitted particulate filter mask as well. The second reason is disposal.
About the only place Al Oxide can go is to the landfill. In some places
it is not legal to put it in the regular trash. If you've got acid soil
in your yard you can actually kill 2 birds with one stone by spreading
used baking soda on it! That said, I agree, baking soda often does not
"cut it" as well as Al Oxide, but please be safe!
