I mostly shoot indoors (actually half in and half out) at our terrace, opening the sliding doors and leaning my targets against terrace barriers.
I used to tape my target paper on some old, used, hard covered agendas which were supported by an old, metal desktop calendar base.
Last weekend I decided to build a pellet trap for myself. I collected some chipboards and some wood. used the woods for back and two sides of the box. Top and bottom are from chipboards.
After assembling all wooden parts I placed an iron metal at the back and screwed it there. I drilled the top for the ropes to be used as handle. I cut a place for the paper clips.
I painted the box with a spray paint. Then I got through the ropes for handle and mounted the clips for attaching my target paper.
I put a lot of old newspapers, foam boards etc. and sighted my Webley Longbow at 7 meters.
Yes I know it is not a big invent or a big job, but I was very happy when I finished and started using it.
