The "release" seems to be a big problem -- getting a (home
brewed) mechanism that cleanly releases so the stored energy
can be transferred to the projectile as a step function.

A bow and arrow arrangement with two bow strings, one slightly longer
than the other.  The shorter string is notched into the projectile and
the longer string is held back by a 'rolling nut' in a similar way to a
mediaeval crossbow.  The displacement caused by the rolling nut
releasing the longer string will not be communicated to the shorter
string or the projectile.
