Yeah, Bob, I guess that's doable but would require pulling the tup and
taking it to a machine shop, then making the ring.  But once I get the
thing up to speed, the tup stays up fine and it strikes single blows
very nicely.  What I need is a nice tach, simple but accurate, so that I
can do better than set the speed by guess & by golly.

Right.  I'm using Whatever Was Sitting Around motor oil, 5W30.  I
think some straight 40 weight would be better.

Well, so far all avenues explored have problems of one kind or
another.  The Continental industrial engine is probaly too expensive a
rebuild; mounting the clutch pulley on the 10HP Acadia is turning out
to be an engineering project; the old car is admittedly cool and
functional but enough of a PITA that it will inhibit casual use of the
hammer.  So in the long run, it looks like either a tractor or
electric.  Either/both of those will have to wait untill I've sold my old
shop.

BAREFACED PLUG: 

    Studio/workshop, 30'x70', 3 rooms, two sets of double doors and
    walkin door, concrete power-hammer/machine pad.  In the very
    center of picturesque Port Medway, Nova Scotia, near general store
    (that has a public high-speed connection), post office, fire
    station, commercial wharf and public park and historic lighthouse
    site.  Heavy duty construction but needs work.  See:

Tell all your friends who think they'd like to get away from the rat
race.  Priced in Canadian dollars which are currently going for about
72 cents in US funds.
