For you woodworkers that don't visit the cannon forum, here is my cannon flyer.
Please print one out and give one to 100 of your friends. 
 
 
 Mostly I make custom cannon carriages for folks with real barrels but there is a lot of non-firing guns on my website at 
www.jmelledge.comThe non-firing concrete barrel on a naval carriage is my best seller.  It is for outdoor display and looks great.  It will really impress your neighbors. 
 
 Thanks for looking.
