His career started early in his life, when as a kid, Bob Gillmor just liked to "blow stuff up". Now he has made this life long hobby a career. He started out by participating in civil war reenactments and experimenting with cannon making in his spare time when he wasn't at his salary job.

Groups can experience Bob and his talented crew in action as they cast, pour and machine these beautiful cannons.  There is lots of opportunity for questions and the experience is great for groups that enjoy seeing the process of "How it's Made".


When Bob is not making cannons, he is also a part of many events like the annual Pyrate Fest at Put-In-Bay, Ohio where he fires cannons every hour to keep everyone's attention.
