Did you clamp the sander in a vise, or hang it by the bucket?
I just let it hang like that in a hook from the ceiling.

After a while I had to add more soda and again after an hour, it didn't leak out, just got packed. It eventually packed itself so hard that it stopped shaking around. That's when I sifted the parts out and put them back in. Re-used the soda and again didn't have to add as much as I took out.
