Posted this on AT around June of 2009... still stopping arrows to this day.
I work for our local School District. We had hired a company to deliver and build computer tables for our labs.
While I was walking through checking on them yesterday, they had unboxed all of the tables and there was cardboard packing materials everywhere.
Saw several pieces that caught my eye(first pic). I immediately thought "Target backstop"
Each piece is made of 4 sheet, cut almost all the way through in 1/4's then fold over onto each other.
They were more than happy to let me haul off some of their "trash".
Got them home, built a simple base, stacked them carefuly, then used a 2 ton bottle jack and the center ceiling joist of my shop to compress them a little tight. Wrapped a strong ratchet strap around the stack and cranked it down.
Arrows go in as straight as when they left the string. I figure it will make for a good Bare Shaft tuning tool.
This weekend I plan to get a roll of pallet wrap, and wrap the whole stack, hopefully to prevent it absorbing moisture and extend the life.
