You didn't give great detail but could you use a construction similar
to a pair of Vicegrips ? Much of the strength of Vicegrips is derived
from the "channel" shape of the handles and 100 pounds is not that
much of a force requirement. Only the teeth of the Vice grip pliers
are really hard metal and if you are only looking for a flat face and
not a rippled grip, that part could be a seperate part of harder metal
and just ground flat. And again, 100 pounds of pressure is not that
much so it wouldn't have to be that hard to begin with.
