Years ago...back in 1979 to be exact...the city of Paxton had a 6 pound civil war cannon barrel without the carriage. They were looking for a volunteer to restore it..and I took on the job. The cannon used to be fired every fourth of July until 1898 when someone blew their arm off with it by improper reloading. They welded the touch hole shut and the cannon soon fell to the ground years later.
I agreed to restore it with one condition...I was going to fire that cannon again. I ordered some 6 pounder carriage plans to hold this 900 pound barrel. I built everything except the wheels. Wheels are very involved with lots of stuff that has to be just right.
I have fired cans of concrete over 3/4 of a mile with this...and every Memorial day..including todays..I get to fire it at the Memorial Day celebration in the cemetery.
