Sand Blast Machines

Just wondering how much some used sand blasting equipment may be worth. Looking at 3 sand blast machines (just the pots). There is a Pangborn and a Schmidt, both 6.5 CF, and a smaller empire one (maybe 3.5). they are in fair shape and are used.

Any help or opinions on offer price is appreciated.

Those are verry small and good for small parts but to do anything big like a tractor rim or a hood it will take some time. You need a blaster around 70 CFM or so to do anything verry big. Then of course you needan Air Compresser that is at least that big or bigger. Bottom line what are you going to do and how much time do you have.

I think you misunderstood my post. They hold 6.5 cubic feet of blast material. 6.5 was not the CFM. These are medium to large portable blast machines.

The type hose , length, and type nozel is about as much as the pot in a lot of instances. Wh have gone to high dollar inverted ceramic that makes the blast material do better but very costly nozels. We 600 lb pots on 385 cfm compressors. Got to have desiel compressors with the cost of gas now. I have seen some complete pots , hose, and nozel bring $600.00 to 1,000 at auction. Again the length,size and condition of the blast hose means a lot. Pot without hose and nozel should be 250 to 300 dollars max.

I bought one at an auction last summer. Just the samll one on 2 wheels,couldn't tell you the brand of how many cubic feet,but I just went and looked it up. Unfortunately with my sloppy book keeping,I only had the whole transaction down as misc. parts. I remember buying a boatload of new bearings,chain,bolts and whatnot that day and I only spent $63 all day,so I'm guessing I didn't give over $20 for the sandblaster with 2 bags of sand. It's like new,works great.

I am a retired sandblasting contractor. I never bought a factory blast pot because they were overpriced and they under-performed. OK, I take that back. I did buy a 20 ton shipyard unit at auction with six outlets but I made alot of alterations.

I am partial to Thompson valves sold by Schmidt. The erodible parts are made of tungsten carbide and last for years of constant use. I used to pay $600 for them. The air valves were full throat ball valves with air-actuated operators.

For a part timer or hobbyist, I suppose anything will do.

You will save alot of sand with remote controls. You will also save time and aggravation should the mixture go lean. The flow can be restored with a quick off/on using a feather-touch 3-way valve at the end of the hose. Tungsten carbide nozzles are worth the money. Use self-grounding (static electricity suppression) sandblast hose with sandblast hose couplings. And don't skimp on an air-supplied helmet and ear plugs.

If you get set up properly, you can make some money and remain healthy. I am in good shape (including hearing) after 30 years of running 750 CFM @ 125 PSI. Your biggest time saver will be using the largest pot you can. There is less need to stop or indulge yourself with a break. Time flies when you are making money. A four ton pot will run all day without reloading. Buy bulk sandblasting sand if available.

Use eBay to get pricing on equipment. Don't forget the eBay "completed listings" too. If you want to build a pot, look at air receivers or propane tanks.
