Built combination safe/how it works

[lunchb0x]

jaakao, are you just after a pic of the wheels so you can see how the two parts disingage to change the combination?

hey phantomhck, there already is a plastic safe on the market, its high end high security made by chubb, no kidding.

Yes you are right about that I'm just curious about the combination changing mechanism, so that when I make a safe lock out of acrylic, I could make it have a changable combination

So please, if you have the kind of pictures, please provide them here. Thank you!

When I make the plastic safe, I was going to use 2 parts for each disk so you can set it variably. On most changeable combination safes now, they have three parts on each disk that can be changed (1 inner and 2 outer).
Get some diagrams of safe mechanisms or even better, to get the displays of just the dial and locking mechanism and copy the idea into plastic.

Oh and another of my ideas was to make small drill holes all around the disks with a pin that inserts into it so you can see exactly what number you're setting and it'll be right on. you'd probably want a milling machine with a rotational axis though for this to make sure it's right.
I'll see if I can make some diagrams if anyone's interested.

I think I might make a safe out of acrylic (plastic sheets), and if I do I'll make sure to put up pictures.

If you decide to do it, this might help. You can weld plex using ethlinedi cloride and a glass hypodermic syringe. I don't know if I spelled that right but it sounds like (ethel-lene-die-cloride). You have to use a glass hypodermic syringe because the plastic ones will melt and jam. I don't remember the needle size but it was much larger than the #26 commonly used for injections. The needle and shank is all metal.
It's very important that the two mating surfaces be very flat. I always machined the edges to be welded. The flat surface of the plex is fine as is.
Don't clamp it until you've welded it. You can see the chemical appears to get sucked in as you inject along the edge. It will generate some heat. It starts to set up and gets sticky fairly quickly but let it set up overnight before testing the weld.
If this is done right the weld can sometimes be stronger then the plex. It's been years but I got both chemical and glass hypodermic syringe at the drug store. Hope this helps.

jaakko, I have a chubb manifoil that I pulled apart to take pics for you but got sent away for work, but I will get them up this weekend if i can work out how to use my camera
