Mike,

Between the speed and the pine test, it sounds like you've pretty much =
confirmed my observations from 1998.

You could skip the see-saw mechanism, and simply balance the ram by a =
means similar to that used in the Weightless Eammer.  I suspect the =
mechanism used in the Grasshopper Treadle Hammer might also work, but that =
was calculated for a slightly different mechanism than a swing-arm hammer, =
so I'm not sure.

Well it belongs to a friend of mine I'm guessing a at a 10,15lb head and =
maybe twice that or a bit more on the back side.=20
he kinda just stuck it together, had to beef up the arm, 1-1/2" pipe, (it =
kept bending)
We stuck a piece of pine in it and stepped on the pedal. it would compress =
the pine about what you'd expect from swinging a ten lb without a lot of =
oomph behind it.

What is the total weight of your ram/counter weight? Do you figure you are =
getting a comparable blow to another TH with the same weight?
Inquiring minds want to know :-)

Thanks,
Larry
