But seriously, it's the simplest setup! Figure out a way to affix the base of your orbital sander to the bottom of a container with a lid, put in parts, add abrasive, run.
The guy in the video used kitty litter (yes) which seems to remove rust also. This blasting soda leaves the coating on the parts which is good.
I'm considering using a bigger container and my good sander and try to run the carb base. It's pretty clean but there are spots I can't get at.
