'It looks like something right out of the battle at Gettysburg,' says Daugherty. The 700 pound cast iron and steel howitzer, designed to use comparatively small explosive charges to propel projectiles at relatively high trajectories with a steep angle of descent, has a 4-inch gun barrel that is 36 inches long mounted on a wooden gun carriage with two 36- inch diameter wheels and took Daugherty about two weeks to build at a cost of about $6,000. 'I've always been interested in the Civil War and cannons, so I thought it would be a good gift,' says Daugherty's 11-year old son Logan. Daugherty said he is not worried about the federal government coming to get his son's cannon because he spoke to the federal Bureau of Alcohol, Tobacco, Firearms and Explosives and found it is legal to own such a cannon because it does not use a firing pin and is muzzle loaded so the government does not consider the weapon a threat. Two days after the family celebrated Logan's 11th birthday, father and son offered a field demonstration of the new cannon on top of a grassy hill overlooking Fairmont, West Virginia and on the third try, the blank inside the barrel went boom and a cannon was born. For a followup they popped a golf ball into the gun barrel, lit the fuse, and watched the golf ball split the sky and land about 600 yards away. 'Any rebels charging up this hill would be in trouble with a cannon like this at the top,' Logan says."
