NEW PROJECT, NEW PROJECT!!!!! I've actually gotten rather hooked on the scale black powder cannon thing so after two very successful cannon projects I decided it was time for a mortar. I have studied a scale Cohorn mortar on Cannon Mania's web site ;www.cannonmania.com and decided that was the one! I just finished the main machine work on the tube - barrel - pipe - - whatever, today and still have to build the sled. This mortar is basically of beer can caliber and will use cement filled beer cans as projectiles! According to the specs Cannon Mania gives 350 to 400 grains of FFG will launch a cement filled beer can close to a half mile! I think the bore will accept tennis balls as well but I haven't test fit one yet. I'll try to post a pic or two later, I might actually have this one finished for the ALA-BAM-ER machine gun shoot next weekend. I have a 2" smooth bore Wierd style cannon that will definantly be there. NOTE: The "Wierd" was an actual cannon design used during the war of northern aggression.
