Sorry, but don't know how to insert an image. May somebody explain?
Finally I learned how to insert images, so now I am able to show you my pellet trap pictures and plan.
Front and Side view
Sliding Target Frame removed
Back and Side view. It may be placed on a table or hanged from a wall at any desirable height. Note the two keyhole slots at the top of the sliding back lid, for hanging the trap if desired.
Sliding Back Lid removed
Inside Trap removed. This inside box is made out of 3/4 plywood with an inside back lining of 1/8" steel plate and filled with 18 lb of Duct Seal.
In addition to paper targets I may hang some reactive targets and build different sliding target frames for more posibilities.
