Ok, before I go and try to design something from scratch, I thought I'd see if anybody has some idea for this project. What I want to build is a central cable lock point for a construction site. It needs to be able to bolt down into a concrete slab with drill in anchors and accept large diamater wire rop choker ends. I'm thinking of using 1 inch cable for the leads. I hate the idea of having to leave equipment out on a job site, but sometime there just really isn't another way around it unless you want to spend three or four hours a day setting up/tearing down. I've tried other routes and have had stuff stolen. it usually seems to be the lock that they go for, as it is the weakest link in the system. I do realize that if they really, really want stuff then they will get it and nothing will stop a tourch. But, if I can make it a big enough pain, maybe they'll move on to something less secure.
Here's my idea to start with. I'm thinkin of a 1/2 - 3/4 inch plate apprx 12" square. countersinking the bolt holes in the corner and using some sort of special nut that doesn't use a common socket to remove. Also, tapering all of the edges to a 45 deg angle so that there isn't a blunt face to try to pound or pry against with a hammer or bar. For the lock I was considering one of the master lock harden "hockey puck" locks. I don't know their real name, but that's what I call them. They are the ones that are just a solide disk about three inches in diam and about 1.5 inches deep. they simple slide over the locking area and secure a pin through the body of the lock. From the center of the plate, I'm thinking for welding some 3-4in diam heavy walled pipe about 4-5 inches tall. in the center of that bringing a sturdy vertical pin welded to the plate. Along the sides of the pipe, cut slits just big enough to slide the end of the cable through and over the center pin. this way I could stack multiple cables on one locking point and then "cap" the pin with the lock and have it still surrounded by the pipe.
Any thought or suggestions please. Or if somebody has a better plan, feel free to post that as well. I HATE GETTING STUFF STOLEN!!!!! Ok, that feels better!
