Yes I get the clipboards at staples for .99 . You might have to trim it a bit to fit your trap but it works great in mine. I print my targets on 67# paper. that is also at staples for about 6.50 a ream. It is heavy enough that pellets make clean holes. Screw a carrying handle to the top of the trap because that duct seal makes it pretty heavy. I want to say mine weighs about 20lbs. I get my Duct seal at Lowe's But I work there and with my discount I think I paid about $1.50 a brick. Wood working is my other hobby so once I had some dimensions it took me about an hour to make. I used 3/4 birch ply I had lying around. Total cost was about $25. Always happy to help out a fellow massachusetts person.
