This will be a fairly sporadic, light duty service. I will mainly be doing
smallish metal parts that have been neglected over the years. Many things can
be handled with a wire brush and some sweat, but I anticipate a few items that
really do need to be blasted for paint removal and whatever reason.
I have a 33 gallon Craftsman oil less compressor that was given to me. It seems
to work ok the last time I used it. It is 110v on a 20a circuit and never trips
the breaker. When it dies I will upgrade to a bigger system. I don't remember
the cfm on the unit, and it is several hundred miles away at the moment.
I have looked at the HF blasting systems a couple of times. I bought their
cheapest system, a vacuum unit, a few years ago for some very light work. I
was not thrilled with it, but managed to use it to get the job done.
I would appreciate any recommendations of things to look for. Outside of my use
of the HF vacuum system, I have zero experience with sand blasting. I don't
want to spend a ton of money, but don't want to have to fight it every time I
need to use it either.
Much obliged,
Roy Parker

Look around on the Internet. I found several sites discussing merits of one system or another. The HF is about the cheapest, but it's not well made and many problems exist.

Because Bob said so. :-)
Kidding aside, I've never done blasting, but have watched. There's debris and dust flying all over, even when using a cabinet. Small investment for protective gear, which can be used for other tasks and other times.

Not sure if this will work for you. Just a suggestion...

I'm Just Wondering, if the cabinet pretty much is its own
protective gear, why should you wear all that protective gear?

A blast cabinet is really the way to go, but a small gravity fed Harbor
Freight gun has worked for me for small projects. I'm on my second one.
They both will use as much or as little air as you care to put through them.
Both will use the same media. The gun is dirt cheap, but the plastic sand
tank will get brittle and break after a few years. You should wear face
shield, respirator, long sleeves and gloves when using the gun. The blast
cabinet will last for decades. The windows will get crazed, but are easily
replaced. Recycling media is more practical with the cabinet. The cabinet
pretty much is its own protective gear.

I'm Just Wondering, if the cabinet pretty much is its own
protective gear, why should you wear all that protective gear?
**** Rather than explain it to you and restate what was already said I
suggest you re-read my previous post. Please note words included and not
included in specific sentences, and note that a period typically denotes the
end of a sentence. Even a poorly worded one. I'm sure you will figure it
out.

As he wrote: "You should wear face shield, respirator, long sleeves and
