Sand Blaster

On top with the door open? You can do it, as long as you don't mind getting blasting medium in every orifice on your body.

I used a big cardboard box and some plastic sheeting to make a temporary blast cabinet for a frame, it was good enough for a one-time use but I still had plenty of sand in my ears.

FYI - the gloves on my Harbor Freight blast cabinet melted after a few years, but the replacement gloves they sell are much better. They're also perfect for making a DIY cabinet.
