Me either.
I think that practice makes a lot more difference than heat settings.

If you don't get an enclosure, you will need to make something
to keep the sand and dust from going everywhere. And you
will need to make or buy something to let you breathe clean air.
Having sand blasted motorcycle parts in a home made "booth"
using a too-small compressor and a siphon gun, I can state
with authority that its a dumb, frustrating waste of time to do this.
Well, your parts will eventually get clean, it'll just take forever
and you will hate it and be coughing up shit for a week
even if you wore a breathing mask.
If it were me, I'd buy a cabinet for blasting the little stuff
and find another way to clean things that didn't fit in the cabinet.
