I know this does not have anything to do with the subject but any way, Im trying to build a Shot Gun that shoots rocks, stones. And since im only 12 and have limited resources its going to be spring powered i am pretty smart, so I have the basics done and so far it's building up quite good, im just wondering what to use to make or use the for the stock_(or butt)_of the gun. Ive allready tried taking one off of a toy gun, but i don't have the money to just use the stock of the toy gun. My brother suggested building one out of ballsa wood, but this ain't for display its for real, and ballsa wood would most likely break while im using the gun. Im building the gun out of two 1in PVC tubes, and the base which holds the trigger, a 4 & 1/2in PVC pipe cut down to 1 & 3/4 in by 3 in forming an oval. Thank You Joe.
