Right-sized air compressor

["George Graham" <georgergraham@xxxxxxxxxxx>]

Ben,

As John VanCamp said you need the right amount of air (cubic feet per
minute) for the tools you are using. Otherwise all you are making is alot of
dust and profanity.

For the quick and easiest removal of stone, I use an electric generator (in
the field) to run a 3.5 hp angle grinder. After making parallel cuts with a
dry cut diamond blade, to within 1/4 inch of the finish line, I'll knock off
the standing stone and clean it up with very course carborundum wheel that
screws onto the grinder. I like the 20 grit that Granite City Tool company
sells. Its cheap and made for cutting granite and all softer stones. I've
found it to be the fasted way to remove a lot of material. The only time I
go to the air hammer and carbide tools is to clean out hard to reach corners
or if a finished exposed surface is needed.

I was grinding some local limestone from western NY and ran into nodules of
flint. The 20 grit smoothed it out ,slowly, and I've passed on carving that
stone again!

Hope this helps
