Air Compressor suitable for soda blasting/painting
#1
I am looking at getting an air compressor. I need to soda blast/sand blast car/car parts and in the end I would like to paint it. I realize it is not a 2k air compressor but I don't want to purchase it if it is not suitable for what I need to do.

I am looking at this:

I also would appreciate feedback/experience from any members on a recommended setup, i.e., air compressor, dryer, blaster, and spray guns.

That is a very nice unit and bigger than most home shop compressors - even with that for sand and soda blasting you will only be able to blast for a few minutes and then have to wait for it to catch up. That is fine for small parts but can be a pain for whole panels.

I have a vintage 1958 Devilbus 5hp and 120 gal tank and it just can't quite keep up with my small blasting setup. Other than that it is more than I ever need.

You know you are old when a tool you bought new is now vintage!

I bought this one at the start of my project 3 yrs ago and had no issues with it. Only thing that I did not do was to paint but it should not have any problems there. Got it at Home Depot and I see its about $450 now on sale. Only draw back is that it's not portable and uses 230 volts but it's easy to wire up. I made an air manifold with plugs along a wall so that I could connect the air hose in different spots in the garage,

It depends on the cfm requirements of the tools you want to use and tank volume. Even if the cfm rating is sufficient but, the tank is small it is going to cycle too often (especially when painting). Just estimating I'd say a min. cfm rating of about 11-12 cfm and the largest tank you can afford. If you want something for the long term and you don't need it now, save up for 5hp or more, 2 stage, and 60 gallon tank. I switched from a 27 year old 3HP 30 gal tank to a compressor like I described. Painting and using high consumption air tools got a easier with less wear on the compressor. Good luck on the search. This is a good compressor for the money and is occasionally on sale at $100 off. http://www.northerntool.com/shop/tools/p..._200350475

The one your looking at won't keep up, you'll have to go steady by jerks. I won't rehash whats been said c9zx pretty well summed it it. (Good post BTW) Most "big" air compressors in the Lowes, Home Depot, Menards, world will run a DIY shop pretty well, but, when you step into the world of media blasting you have to go big. I have one of these http://www.tptools.com/1536-Champion-Abr...l?b=d*8016 and really puts my air compressor to task when I have a lot to do. Even at 5 h.p., 2 stage, 60 gallons, my outdoor system will outrun it and I have do the blast-wait-blast-wait thing.

Chris,
Any 2 hp compressor will not work for what you want. I've sold air compressors for 30+ years. The mistake of over 50% of the people that purchase new compressors is that they look at price and end up buying a compressor too small for what they want to do. What you discribe, you need a min of a 5HP, 2 stage compressor with a cfm of no less than 25 CFM @ 100PSI. That being said, you will be spending closer to the 2k that you don't want to spend. Shop around for a used compressor that meets the above specs and you'll be a lot happier. A smaller compressor will work, if time is not a factor. You will be able to work for a few minutes, and then wait for the compressor to build up pressure, and then a few more minutes. Really gets to your patience if on a project. Good luck. If you purchase the right size compressor, you'll be happy for 20+ years, or purchase on too small, and end up buying a new one later.

Thanks for the responses, I am now considering the two recommended 60 gallon compressors -- the Quincy is nice (US engine versus Chinese).

What about soda blasters? Do I just pickup a cheap one at Sears or Harbor Freight?

I got the Quincy 60 gallon Chuck recommended, nice. I noticed the tire on the passenger front was low so the first thing the compressor was used for benefited the Mustang :-)

That isn't going to cut it for any type of blasting I'm afraid.

The compressors that jbojo and Chuck linked to will get the job done but as stated, there may be some wait time involved depending on the demands of the specific tools you are using.

The best bang for the buck is this compressor from Harbor Freight.

I know, I know but research it and you will see that it is fairly well regarded and not made in China.
