Well I also have a 5hp upright that I use for running my paslode roof and framer guns, it works great for them but try running a impact on a wheel, by the last lug nut its running out of power

I bought the 80 gal fixed upright to paint with also, hate it when your paint starts to faid out due to low psi

I think the Speed Blaster would do fine on a smaller compressor.

I agree. The air that goes out must be put back in. The pump does that. The bigger tank maintains the pressure longer. I have both types, the 2 hp pancake compressor and the 33 gallon 5 hp. I wouldn't be without either one of them.

 

Well, all the craftsman ones are 1.6 HP, I would think this would be suffice for smaller parts. I think an 80 gallon compressor with a a 5 HP motor is overkill for what I'm tryign to do.

 

I was talking about 5hp with a 33 gallon tank. Mine is 10 years old. BUT the compressors they sell now are different. They are oilless so the horsepower is different. What is important is the SCFM. That stands for Standard Cubic Feet Per Minute.

10 SCFM at 90 PSI is what mine is and it means the pump can continously put ot 10 cubic feet per minute at 90 PSI. When you buy air tools they tell you how much air they consume. It doesn't mean you can't buy a tool which consumes more than your compressor, it just means you will have to stop to let the compressor catch up. But if you have to stop too often then it is a little frustrating. Also keep in mind that some tools are not continuously using air, like a stapler or nailer. Some are, like a sander.
I suggest you look at different tools you might want to get in order to get an idea what they consume. That will help you make a compressor decision. Again mine, at 10SCFM at 90 PSI will do everything. Painting and prolonged sandlasting only barely but it will do it. Thats why I believe it is the best overall choice and bang for the buck. Good luck.
