http://greystarcannontech.homestead.com/star.html Rough up of some wood work and the wheels are from Amish country, chariot racing wheels with bearings. Ended up reworking the tail of the yoke, needed a bit more angle to make room for the elevator. Some more work on the metal reinforcing around the cheeks. Finished enough to be able to fire it. And the moment we had been waiting for. Make powder packets with aluminum foil and use another full of cornmeal for wadding, creates a big deep boom.
