You can put a crankcase heater on it that should enable starting when it's cold. They are common on refridgeration compressors to solve the same problem.

I'm also shopping for an air compressor.
I just came back from Home Depot and it looks like the Husky line they carry is made for them by Campbell-Hausfeld. I was getting frustrated trying to find a price on one when I realized that the price sheet on the wall that was labeled Campbell-Hausfeld had the same part number as the Husky I was looking at. A little searching on the web indicates that the part numbers are similar, but I don't find an exact match.
At any rate the specs on the model previously mentioned:
Model: VT6314 Price: $399
3 year warranty, 6.5HP Peak/3.2HP Running
60 gallons, 10.3 SCFM@90 PSI, max pressure 135 PSI
100% Duty Cycle, cast iron oil lubricated pump, 240 Volts,
1070 RPM
They claim you can run a sandblaster with it - is this realistic?

With over 10 CFM sould not be a problem blasting.
This sounds like the CH I am looking at at TSC. Hmm, I may have to take a look at HD.

How big a sandblaster?/w3tcompact/icons/wink.gif I've got one that's simply a one quart can like a paint gun and I've got one that holds 100# of sand. You could use either of those with that compressor.

Thanks Bird. Right now, I just have this vague notion that I might want to use a sandblaster sometime. I expect that the 100# unit would be more than sufficient for anything I might want to do.

How you read the ratings on equipment, and what ratings you read are a bit important. CFM at what pressure, not just CFM is the critical rating.
Sandblasters, you need to consider Nozzle opening. 10CFM at 90psi will sort of run a 1/8 nozzle sandblaster. When you move up to a 3/16" nozzle, you are going to need a whole lot more air, at least 25CFM@90psi, or you'll spend a lot of time waiting for the compressor.

Franz, I agree that sandblasting takes a lot of air volume, and I certainly don't claim to be any expert at it, but my 100# sandblaster is a Craftsman and the gun has a common 1/4" inlet port (I use 3/8" hoses, but 1/4" quick couplers for nearly everything). And the specs in the manual are as follows:
Minimum air requirement: 4.5 CFM @ 40 PSIG
Minimum air pressure: 40 PSIG
Maximum air pressure: 125 PSIG
The manual has a part number for the nozzle, but doesn't say what size it is, but I think it's the 1/8" as you mentioned.
While I wouldn't necessarily recommend it for big jobs, I have used it to sandblast two 5' x 10' trailers before painting them.

Franz,
"Bird, you forgot to point out that it consumes as much power to build the tank from 125# to 175# as it took to get to 125#.
Building a tank pressure to 175# is a negative investment, when doing it merely for additional stored CF of compressed air."
Couldn't you just adjust the pressure cutoff switch down to 125-130# if you had one of these. Seems to me that the unit should last most of a lifetime working at the reduced duty.
Just my opinion,
Don

Sounds logical to me, Don, but the fact is that I've never personally owned one of 175# compressors and never worked on or tinkered with one at all, except to turn'em on and off and drain the water out of the tank. In other words, I don't know enough about'em to be the person to ask.

A well designed compressor runs most efficiently in the" cut in- cut out" range that it was designed for. One cubic foot of air at 175 PSI is more than one cubic foot at a lesser PSI. A 30 gallon tank at 175 PSI has more reserve than a 30 gallon tank at 125 PSI. A compressor that produces 10 CFM at 175 PSI produces more air than a compressor that produces 10 CFM at 125 PSI. In intermittent use a good cast iron compressor should last your lifetime.
