Go to the hardware store / home center and buy a 1"dowel at least 6" long ( or cut a small chunk from broomstick, or cut a chunk from a scrap 2x4). Buy a screw(s) matching threaded holes in barrel. Drill holes in dowel a bit larger than screw diameter, screw it on. Should cost around $1 if you use an old dowel, or hunk of wood lying around, maybe $4 if you buy some wood. Not pretty, but good enough to tie you over. I hope this doesn't violate the "make it yourself" exclusion.
Good Luck, Bob
