Haven't done it.  Planning to try to run a 300# air hammer from one.

On a guess, I think it might be a good idea to include a jackshaft in
the setup.  These engines only fire every few strokes when at idle.
When you load them up, they slow down, the centrifugal governor cuts in
the ignition and they fire on every (power) stroke until they come back
up to speed.

With a mechanical power hammer, this might mean that when you clutch
the hammer, it strikes a couple or three blows at one speed and then
speeds up a bit.  A jackshaft would act as a flywheel and even that
effect out.

I *have* run a 24" bandsaw direct from a small De Laval.  Worked great
for cutting a lot of wooden shakes at an angle although it was a
little scary.  (Saw and engine were on dirt, just staked down, and the
saw was running a bit fast, too.  Pine isn't supposed to smoke when
you saw it. :-)
