I've come up with a low cost target holder. Here' what you need:
Commercial size compound bucket w/ top (free from jobsites!)
1-1/2" dia. pvc piping (approx cost $3--$4 for 10' piece)
bundle of lath (approx. cost $6 for about 20--25 pcs)
Drill 1-1/2" hole in lid of bucket, centered.
Cut PVC pipe into (3) 36" pieces (You'll have a 1' piece leftover--give to your kids to play with, Home Repo cut them for me gratis)
Drive screw into pvc pipe 11-1/2" down from one end.
Place pvc pipe into hole in lid, place lath into pvc pipe on top of screw. Top of lath should now be 6' from the ground. Take another piece of lath and attach as a cross piece at top of upright lath, with battery screw gun. You now have a "T" shaped "frame" that will stand as 6'. You can vary height by breaking upright lath pieces off at shorter heights. Staple target across top and down center lath piece. If it's windy or unsteady, put rocks, dirt, or sand in bucket at range location.
PVC piping should last awhile even with several hits. Lath can be replaced easily and cheaply. You can break this all down, and take 5-6 targets in car to range for set up.
Whaddya think?
