Is the horsepower rating of the compressor strictly that of the motor, or are there other factors involved? I also didn't know about a Sears lawsuit. What's up with that? I've got an older Craftsman 5hp with the 30 gallon tank, 125 PSI max, CFM rating unknown. Anyway, it's been sitting around for a couple of years with a cooked motor. I need to start doing some bead blasting soon as part of a new business. I've got an old nameless blast cabinet as well, that I've only used once (just to test it, running off a bottle of nitrogen). I have no idea what the nozzle size is, or anything else. Anyway, just last week I got a new motor(5HP GE) at TSC, installed it and a new belt, and am quite happy to have air again. (been finding excuses to use a drawer full of air tools that have been collecting dust). I knew when I bought the motor that the compressor was really too small for blasting, but was hoping to "get by" until I can make enough money to upgrade. Listening to this thread, I'm a little scared that I won't even be able to do that. I was planning on getting the IR 7hp single stage 100 gallon unit that TSC sells (my brother has one and loves it). Should I go for a two-stage, and if so, any recommedations?

The good news is that the 60 and 80-gal kobalt compressors are not made by CH and are American made with 3 year warranty. The bad news is that Lowes is going to quit carrying the 80-gal 2-stage. The Home Depot Husky large 2-stage compressors are CH and it even says so on the unit.
Harbor Freight has those U.S. Generals with units of varying specs but don't seem to match the Kobalt 80-gal. The other option is to order an Eaton.
Edit: I bought one of the Kobalt 80-gal 2 months ago and so far so good. It is quite. It was supposed to require a 40 amp breaker and it has been working on the existing 30 amp breaker. I'm suprised by that. Also, that is the first time I've paid to have anything delivered but that was $50 well spent. It weighed 500pouns and was top heavy. They put it on the outside covered platform for me.
FYI! Compressing air up to 100 PSIG increases its temperature 600°! In practice there are several cooling devices employed on air compressors so the discharge line only sees probably 325°. Still too hot for nylon tubing.
By the way that heat of compression is what makes your diesel operate. When you compress air to around 350 PSIG ( typical for a diesel ) its temp is probably 1500°. (only guessing here )
