The little spherical tank was originally a sand blaster in it's own right. A gun using a compressed air line sucked the sand up by venturi action, and the used sand was sucked back into the pot by an attached vacuum cleaner down the outer of a co-axial tube, the centre of which was the 'sucked up sand' line. The blasting nozzle was surrounded by one of several shaped rubber cups that restrained the used sand. If you look at the 'skirt' of your tank, those holes were where different shaped rubber cups were stored. They were intended for small scale car rust removal - just small spots of rust - the shaped rubber cups were made to fit round things like door edges, and also there were flat ones for spots in the middle of a panel. Tediously slow to operate if doing more than the odd square inch.

I sold mine about 8 years ago


What grit are you using?

ksor:
I don't know what sand is used !  :loco:

I just used the sand in the "tank" and MAYBE it's like the sand in the new bags - I don't know  :Doh:

The way I'm going to use it - cleaning small parts - it will Work fine :drool:

Arbalist:
Good job! I've found my sandblaster invaluable. I normally use Aluminium oxide grit in mine but may switch to glass beads when I refill it. One thing I found is that it can be run on a very modest compressor, mines only a 25L 2.5hp unit and it works fine.

awemawson:
Need to keep the pressure up to 90 psi or more - so if your compressor struggles use a smaller nozzle. Grit impact speed is the key, not grit volume.

Don't use sand unless you want to develop silicosis.
