No I didn't post this in the wrong group. Well sorta kinda didn't. On one the forums I still read when it isn't down somebody was talking about home(shop)made machinable wax. It reminded me that I have some commercial machinable wax on the shelf in the shop. My plan was to use it to make temporary molds for making rubber stamps. Then when I was done I could melt it down and recycle 99% of the wax for the next time. That made me think of the first time I saw somebody using machinable wax to make very highly detailed and refined wax blanks for gold jewelry casting.
A customer of mine who scared the hell out of me because they were such high risk. I pulled tricks and did things for detection methods I never used anywhere else, and I chewed them out for not letting me put cameras on the roof, and detection equipment in the ceiling after somebody cut a hole in the roof while they were in the back shop working. The only discovered it because somebody saw a tile out of place. I was mad because I told them that would happen. Well, not while they were there, but I told them somebody would come in through the roof. At least the let me do things in case somebody came through the wall from an adjoining business... which somebody tried.
Actually it was probably more dangerous for that burglar who tried to come through the roof/ceiling than it was for them. Those guys all packed heat all the time. In their new location they did some of the things I suggested. I was out of the business by then. In fact they wanted me to do some upgrades before I got out, but I told them to use the new company so they would have somebody who would support their systems.
Just for Les. Nobody else read below.
I did some welding recently that you could make fun of if my fragile ego could take the criticism. Stacking tacks with .030 gasless flux core to make a tool box smaller after cutting off the ends. I spent a lot of time chasing holes. Makes me wish I'd done it a little differently and spot welded it or used rivets. I swear I think it was easier patching muffler skins with a torch and a clothes hanger back when I was a kid.
