I'm considering buying the sand blaster shown at the link, however, I'd
like a little input as to whether I have enought air compressor before
I shell out the $$. I would use the blaster to finish burls similar to
the one in my privious post and and other like tasks. I know a blaster
takes a lot of air....I think I'd need to run it 15 - 20 seconds at a
time then let the tank charge a bit. I've done a search but I think I
need to have input from someone who has a similar sandblaster.

My compressor says it will put out 7.2scfm @ 40 psi. and 5.6scfm @ 90
psi. and this is the blaster I'm looking at:

If it is for occasional use only, here is a cheaper one from HF.

Tom,
Your system is a medeium output unit, but for intermittent use, the size of
your storage tank will have more to do with its' performance than the actual
compressor. You can add an auxilary tank to your system and increase your
short term output considerably. Just be sure it is ANSI approved for the
working presasure you expect to be using.

I don't know why, but I was not able to get your sandblaster link to work,
so I'll assume that it is a 5 or 10 gallon pressurized tank system similar
in design to the one that I have. Mine is one of the "made in china"
pressurized tank type models that are readily available at Northern, Tractor
Supply and other retail tool stores. The cheaper "non pressurized" tank type
blasters that work on a venturi technique to mix the sand with the air
stream are considerably less expensive, considerably less effective, and in
my opinion, not worth buying if you expect good results and minimum
headaches.
Your present compressor isn't big enough to run a sand blaster continuously,
but if you add an additional storage tank to your system you will be able to
easily run a sand blaster for short periods, even considerably longer than
20 seconds at a time. The compressor will take longer than it does now to
recover and shut off, but the added tank capacity will give you much more
blasting time at useable pressure. How much time will depend on how big your
total tank capacity is and not how big your compressor is. The compressor
size will determine how fast the system recovers back to full pressure (how
long your break time is) before you can blast again. You will also need to
seriously consider adding a good moisture filter to the air line ahead of
the blaster or the sand blaster will frequently plug up. Only dry sand and
air will work. I found a filter at an automotive paint supplier for about
$30 that uses rolls of toilet paper as the filter medium. This proved to be
a very effective and economical way of getting dry air for me. A fresh roll
before each day's use and I can get dry air all day and the roll doesn't
even have to be Charmin. Even the cheapest stuff does a good job. It is also
a good idea to filter your sand before you put it in the tank. The bagged
blasting sand that is available from Lowes and Home Depot are not graded
very well and will have some oversize particles in them that will also plug
your sand blaster. For trouble free sand blasting you need well graded sand.
You can buy a tool for this, but a kitchen type wire sifter will do the job
too, and it's a lot cheaper.

Some years ago I had an 11 cfm 2 horsepower ( 2 real hp) compressor with a
20 gallon tank. When I used it for sand blasting I had an old 100 lb propane
cylinder (totally cleaned out and the fittings replaced) that I would
connect via a tee in the air line. This combination gave me about 5 minutes
of blasting time before the pressure was too low to use. I have now upgraded
to an 18.4 cfm at 90 psi system with an 80 gallon tank. When sand blasting
with this system the compressor stays ahead of the blaster and I can do
continuous blasting until my whole 10 gal tank of sand is gone.

Charley, Thank you very much for a very good discussion about a subject
seldom discussed here. I don't know much about the mechanics & equipment
required for sandblasting, but I do know that no matter how good the
wood artist, he can't use the technique if he can't blast the sand. I
still don't know much about the equipment needed, but I know more than I
did before reading your post. Thanks again.

I have a pressureized tank sandblaster that I use for automotive work,
though I haven't used it in a while - my Sears air compressor was rated 7.2
CFM at (as I recall) either 40 or 60 PSI - it would run the thing for about
15 seconds and then I'd have to wait for it to refill. My current
compressor will produce 19CFM at 160 PSI, but I havne't needed to sand blast
anything in a long time -

the message we are sending you is that you need a LOT of air, and also that
the smaller sand blasters are more of a problem (clogging, etc). you may
wish to have a sand blast cabinet and save some $ on media.
