Some years ago I bought one from HF to take the rust off a WW2 jeep frame.
The one I got came with a tank about the size of a standard gas grill tank,
in fact it probably was, and a hose, mask, etc. Best I can figure, if I used
that rig to do the job, I'd probably still be working on it, twenty years
later. Essentially the things are worthless for anything beyond light hobby
work. I borrowed a rig from a buddy that sandblasts tombstones, and the job
took about an hour. I can see why a rental place wouldn't have one. You can
do a lot of damage in a heartbeat, if you're not careful

Thanks. Any suggestions for sandblasters?
Is the problem that these cheap ones just don't blast hard enough? Not
enough volume?

Depending upon the compressor, you can get all the CFM you need, but the
nozzle size and that little bag won't pass enough media to do anything.
Think water pistol vs. fire hose

Among other things...
You need a "pot" sandblaster for serious work, and if you're doing
really serious work an air supplied hood with an air dryer.

Sandblasting is a function of air pressure and grit size and, to a lesser
degree, how often you have to fill the reservoir.
HF sells only itty-bitty grit, suitable for jewelry making. You'll have to
get the larger stuff at Graingers.
The sand-blaster itself should be ample. I got one to knock the rust off
some steel garage doors. Tried their material, bah. Tried salt, also bah.
Got some real abrasives and the job went double-quick. 'Course there's a
pile of abrasive to vacuum up...
As for renting a compressor, you can probably buy one from HF for the price
of a rental.
