cool I use zip ties instead of wood and bolts, down fall, you hit one and you have to replace it. Up side you hit one and you are not replacing an arrow. I like these targets.
I built a target like that using 1 1/2 fiber roof deck insulation, used under built-up roof applications. Can be bought for cheap from any commercial roofing company. 1 1/2 inch X 24" X 48". Great for wood or alum arrows. Hi speed carbons weld themselves into the target.
Big outlet stores like Wallyworld are compressing their cardboard into bales, there is a local company buying them and you might be able to buy from them. I got one 500 lb for $40 and still shooting it after 4 yrs. If you have a way to handle them, with a little research you could pick one up.
