Back in the day, I was part of a group that did medieval battles.

That sounds like the stuff I did in the SCA, when a friend got me interested in what they called "combat archery." They take their safety inspections very seriously, to the point where they inspected arrows after each scenario just to make sure the arrows hadn't been damaged.

The stroke is much too short. I had to build one from scratch. It resembled the cranks attached to wheels on the old steam locomotives. I could move attachment point on the wheel in or out to change stroke length. Used an electric motor with a reostat to control the speed.
