Thanks for the welcome.
I wish i could share reviews with you, by way of my ebay feedback. However i list the item as "private" so although you can read the feedback, you can't really tell what the feedback was left for.
Having said that, my feedback is 100% and can be viewed on ebay under seller "onscreen5".
I'll do my best to describe it's function. If you can picture a cylinder about 3/8 diameter and 1/2 inch tall. one end has internal threads, the other a 1/8 thru hole. at the bottom of the cylinder is a 1/4 inch cross hole.
into this cross hole slides the end of the cb6000 lock pin and lines up the hole in the pin with the hole in the bottom of the cylinder.
The second part resembles a set screw, or a bolt with no head. except out of the end of it protrudes a 1/8 pin. This bolt threads into the cylinder as the pin on the end slips through the 1/8 hole in the cb6000 pin , then through the 1/8 inch hole in the bottom of the cylinder.
Now in the end of this bolt is machined a slightly oval counterbore. This counterbore matches the end of the third part, which is the key.
they're machined as a matched set and i change the width and the radius of the oval randomly from lot to lot.
Really the only way to get it open without the key would be to cut it off or a screwdriver could be forced into the oval then used to back it out. Trouble is the two parts are such a slip fit that any tampering or damage done to the oval in the bolt will prevent the key from going in again without the damage being noticed. so without the key you're going to damage it getting it open which means you're busted.
It does have to line up with the 1/8 hole in the pin, then bottoms out against the pin, so it doesn't rattle at all and there's a flat along one side of the cylinder so it can be installed closer or farther away from the shield by about 1/8 inch.
My design. I also make a security insert that functions kind of like a chinese finger trap using rubber pegs for the 3000 and 6000.
