Sandblaster

The siphon feed types are basically nothing more than an air gun with a siphon feed hose that sucks the grit frm a container and mixes it with the air stream as it exits the gun. Not as "powerful" as a pressurized tank model, but certainly adequate for occasional and general use.

Enclosed cabinet types are intended for small parts and are economical in the sense the blasting grit is recycled through the system instead of lost as is the case for open-air blasting.

Also there are several types of blasting media that you can use. Glass beads, carbide (normally used in a closed cabinet types), and sand. As mentioned, harbor freight sells several types and models of blasters. For occasional and general use, particularly smaller parts or areas, I would recommend the $29.95 portable siphon model they sell. The grit container holds up to 30 pounds of media and it is an extremely simple system. Heavy moisture can still cause clogs, but these are not nearly as prone to moisture issues as the pressurized tank types.

A relatively inexpensive moisture filter on your air supply outfeed will eliminate the majority of problems when blasting.

It kept getting clogged up and I tried everything I could think of, including asking about it in this forum.

I think the longest it ran was a minute or so before clogging again & again & again. It was one of the most aggrevating experiences I ever had. I finally wound up putting (5) 7mm Mag rounds through it which gave me great satisfaction.

I then purchased a Campbell Hussfeld hand held gun @ a Wal-Mart store. It was about $12 bucks. It has a hose that you put inside the medium and hook it up the air supply and away you go. Now, don't get me wrong, I wouldn't want to do any big jobs with it, but it is sure fine for small stuff.

I sent you a URL @ CH with details of this item. It's cheap and worth a try.

Some time ago I purchased the #38375 blaster from Harbor Freight. However, unlike Don, I TRIED to use mine. Had PLENTY of PSI & CFM. My sand was dry & sifted (Black Beauty Extra Fine).

PS
Don,
If you read this I would sure like to talk to your friends that had such great success with their Harbor Freight units. Maybe they could tell me what I was doing wrong..... ..

Maybe the one I had was a lemon, but that doesn't make scense as its a very simple unit.

If you want to communicate outside this forum list your e-mail address in your next response and I will get in touch with you.
