Made some half door hangers yesterday. Works well, cheap, and it's nice to have them out of the way and safe. Requires exposed studs in wall (see pics).
cheaper and easier than mine, but I didn't have eyebolts laying around like the stuff I made mine from and I was bored.
1 - 2x4 (2.5' minimum)
8 - 3" wood screws
16 - 1" wood screws (anything 1/4" and above will do)
4 - flat steel mounting plates w/ holes
1 - drill
1 - 5/16" wood drill bit
1 - wood saw
plus jeep pic
Cut 2x4 into 13" to 15" sections.
Drill parallel holes on each side of both pieces at the very edge.
Screw mounting plates over sides that the holes go down for support and you get this.
Now screw the 2x4 into the stud w/ the 3" screws and hang your doors.
A couple of close ups
As you can see the driver's side door doesn't slide completely into the holes, but it works. A drill press would've been great.
I took lots more pics, but figured that was enough. Ask if you want more.
