Thank you Geof.

This is a very useful bit of data, it'll save me some experimentation for
sure.

 Just as a data point, a friend with a Spanish air hammer (~1cwt) has
air valving about that size. the rear cyl is ~6" and the front is
approx4/5". Air pressure developed is 15psi by the compression cyl.
These measurements are approximate, as it is a while since we measured
it.
