I dont know if this has been posted but I built a inexpensive yet portable shooting bench from things that I had around the house and way toooo much time on my hands.
Materials:
1. Black and Decker Shop Mate
2. 39" x 18" x 1-1/4" subflooring plywood
3. 2" x 2" x 24" scrap piece of pine
4. 6 - 10 2-1/2" deck screws
5. scrap pine to face with
6. glue, nailgun, sandpaper, stain, and polyurethane
7. one, two or so plastic chairs
I took the scrap piece of subflooring and cut a shallow curve on one of the 18" end.
Next I found the center line of the plywood and glued and screwed the 24" piece of 2" x 2" to it.
Next I faced the plywood with scrap pine cut to size and glued and then nailgunned to the plywood on 3 of the 4 sides.
Then I sanded, stained and finally put 3 coats of polyurtehane.
The end product is a very stable and effective yet portable shooting bench
Just remember that rifle and 22 LR ammo is optional!
