I checked the Cengar website and the saw needs 5 3/4 CFM at 75-90 psi.
Perhaps I might just manage it with this compressor, or am I pushing my
luck? I figure that inflating tyres and blowing away debris would be fine
with a little compressor like this.



I question the CFM required to run your saw. Many manufacturers do not rate
the CFM at 100% usage so you get a poor indication of air volume needed to
run the tool.
Either way anything less than a 3 HP compressor will allow very intermittent
use of the tools you mention. I have a Porter Cable 7 HP, ( yeah right,
really about 3 HP), compressor that pretty much does all I need it to do. It
is rated at 9+ CFM at 90 PSI.. I had a real 2 HP compressor for years that
really was inadequate for much air tool use.
If you need a limited amount of air, a larger tank will get you by with a
small compressor. Keep in mind that once the tank has run down, recovery
time is very poor so you will not have air when you probably will want it!
