Hello Mike:
Small, direct drive compressors tend to be very LOUD; belt drive turn slower and are somewhat quieter. For many builders this is an important concern.
Any compressor will be adequate for the rivet puller. Take a good look at the CFM demands of the other two tools and get the MOST EFFICENT tools (lowest CFM at rated RPM) you can afford - especially the drill. The cutoff tool is nice but, in my opinion, as a kit builder, rarely used. ( Comes in handy for cutting off an old muffler off the old Buick though !)
That drill will be in your hands a lot - get a good one.
I am using a belt-drive 230 VAC compressor delivering 120 PSI regulated down to 65 PSI for a drill and 45 PSI for the riveter. I can't give you a CFM rating because all the specs are metric (it's a salvaged Japanese oilless piston-type compressor) but I can tell you it will drive an ARO 1/4" air drill ( my most efficient)continuously. The other two 'junk' drills are air hogs and I use them for opening up pilot holes to #30 and #20 holes - always drill a #40 pilot hole !!! An in-line oiler is a good investment as well providing you are not using those lines for an air spray gun.
Email if you have questions - Happy Building

I have purchased a few air tools to get started on my kit: The
Harbor Freight rivet puller; A Chicago Pneumatic Mini Air Drill
(model 7300RQC); A Chicago Pneumatic 874 3" Air Cutoff Tool.
I need help in selecting an air compressor that will adequately run
these tools... I guess that the parameters are xxx CFM at yyy PSI.
I am aware that a small compressor may work fine, but cycle
frequently. Larger ones are costly and could trip a 15A breaker.
What is a good compromise? What are you using?
Thanks in advance!
Mike
