Sandblaster recommendations

I know the sandblaster topics have been beat to death, but most discuss the media. I am looking for a review or a recommendation for a Pressurized Blaster setup. I am looking at three right now:

1. http://www.eastwoodco.com/jump.jsp?i...emType=PRODUCT
2. http://www.northerntool.com/webapp/w...70_17798_17798
3. http://www.harborfreight.com/cpi/cta...emnumber=34202


And since the cost of renting something similar from United Rentals for 2 days is just about what either of these 3 will cost shipped to the house, I figured I would buy it instead of wasting the money on renting. I may still have to rent a compressor, but we will see, maybe I'll buy a new one as well.

Right now I am leaning towards the Eastwood one, only because of the company, most of the stuff I got from them has been pretty good. BUT if someone has something else that I should look at, let me know. I am open to all suggestions. I am open to the Harbor Freight stuff as well, as long as it is good stuff. Not all HF stuff is made in China.

Thanks
Rust

I use mine quite a bit, and thus volume & pressure is important to me. If you're ever going to do a frame or something that size, don't skimp.

I have this one:

http://www.northerntool.com/webapp/w...t_6970_517_517

Bought it, REFURBISHED, about a year ago from Northern (for about $125 cheaper that it is on the link) & love it. It's a solid unit.

One point, you HAVE to have a water trap right at the unit's input, regardless of whether you have one on the wall, especially if you are going to run it outside where the temp is different from where your air supply is. During the winter, my 50' hose generated a ton of water by the time it got to the pot.

As you can see here:

i have used a couple o' el cheapo's and am going to buy mine from harbor frieght for about $90. yes chinese and arent they all? anyway i think they are all about the same- the most important thing is your compressor being designed to run all day and not to use sand

I'd be real careful thinking about buying that Northern blaster.
Here is just one review from someone who bought the smaller unit for ~$100:
Quote:
"The dead man valve uses a pin into a rubber hose to stop flow. The pin was thru the hose the first time I went to use it. You need to take out the valve assembly and replace the hose. Next the nozzles last two or three minutes you have to make your own using tool steel then harden them. I was using Jetmag. My friend has the same unit and had the same problems
Numerous other people had the same problem and more. It looks the one you are considering uses the same "rubber tube pinch off valve".
I just came back from"The Freight" where I wanted to buy a smaller blaster $49 on sale, but you know how they are in keeping items in stock.
It is smaller, but it has a ballc-o-c-k valve instead of the bs rubber tube.
BTW, has anyone heard of the Texas blaster ?
texasblaster
It looks a little better than the cheapie Chinese ones.

Honestly, What makes a good pressure blaster? Most of them seem to have the basic components:

Tank, size to your liking, as long as you can get 30 min between refills I think I am ok, I need a brake too.
Water trap, Most of them seem to have these, and the disposables are cheap.
Hose and hose clamps, Hose size matters, but if it has cheap clamps I could replace with better.
Valve, this seems to be a preference type deal. Deadman, or ball valve?
Valves to control air and media, this is where I think you need to watch. Do all pressurized tanks come with a valve to control media flow???

Did I miss anything??

Does the ball valve work ok, or does a deadman valve work a lot better?

I used the Harbor Freight model to do the frame and other parts on my Model A. Worked great. Being a bit thrifty,I laid down tarps to catch the sand so I could re use it. I learned that you must put the sand thru a screen,before you refill the blaster,with used sand , to get rid of the stuff that will plug the nozzle .

I have the Harbor Freight model. My opinion? Don't buy one and take your work somewhere and have it done. By the time you run your compressor to death, buy the media and the PITA$$ factor, you'd be better off sending it out. I use mine now only on little touch up stuff. I use my cabinet blaster more than anythign.

My $200.02

HI
i got the harbor freight one (50$ on sale) a while ago and i cant get it to work consistently.
not sure if my media is too big, pressure is set wrong or there is water in the line. i am doing something wrong or it totally sucks.
it seems like it is clogging. i turn it on and it comes out for a second and then stops. when i shake the machine a little more comes out for a second and then stops. that works for another 2 or 3 times and then nothing comes out.

i am using 125 psi which is what the manual said. i have the largest nozzle that came with it in and have tried medium black beauty, fine black beauty, and plain sand.

any suggestions!!

Well at least you are getting a good workout.
I bet your sand is damp, clogging it up.
i have a siphon blaster right now, but I plan to buy the $50 one soon.
Spread the sand on a tarp in the hot sun for a day to dry.
Sift the sand thru a screen to filter out any big pieces.
Let us know if it works better.

For a sandblaster to work properly (or at all) you need to have a DRY air supply! Moisture in the air supply is the Number one cause of blaster problems because of the high volume of air required and the fact the compressor is usually worked to point of producing very hot air. A moisture separator on the blaster tank itself is almost a must and it should be connected to about 50 ft or so of air line to give the air at least some chance to cool before reaching the separator. Make sure that both the blast media and the air are both DRY!

I see you are from Ny. We are in some wicked heat wave here in the northest along with humidity very high. That means the comp will run hotter and condense even more water than normal, despite an add on seperator, or two.

I am sure you have a water problem.

Not sure how that HF is plumbed, but my old TIP unit has pressure on top of the sand, plus a hose running down to the mix-valve at the tank bottom. When I got it new in 1976 there was no inline valve in that hose to the mixer.

It used to start to plug at the mixer and finally stop the sand, but still had air. I used to keep pliers handy to pinch that hose for a second to help purge the damp sand out of the mixer. That got "old", so I put in a inline ball valve. Now just close it for a second to blowout the clog, or on REAL bad days, I close it a little to make up for the dampness.
