Please excuse my ignorance, but for further clarity what is 30# of weight? Pounds, kilos, tons? Thanks.

Somewhere on this forum, years ago, we looked at the method of flattening warped 78rpm records without affecting the grooves. If I remember correctly this was much like your "next time I do it" using glass on both sides (although I guess the temp would have been less).
Really well done, a ground breaking repair !THUMBS!

Before Twitter made # into a hashtag it was shorthand for pound.

Thanks, perhaps Mr.PM would like to include this backflash flattening method in the tips and tricks section?

Here's what the key should look like.

Here's how that was determined:

And the dimensions, in inches:

Of course this is assuming that the tumblers are squished together with no gap. I'm guessing that about .005" need to be added per tumbler to allow for corrosion and surface imperfections.

Now to try it out and see if my brain matches reality !PUZZLED! :lol:

And now i've got a functional key. Blanks are on the way. But this will work in the meantime.

Now to get the Machine dealing out KitKats, instead of Crunch's. I'm just rebuilding the mechanism from scratch. Never used a candy bar as a dimension before.. :HaHa:

You do some amazing work and are clearly very skilled... but I can feel the purists on the forum squirming in their seats as you remove one original part after another and make a new one. :lol:

I would personally prefer to alter the chocolate bar rather than the machine.

Or I could just make a new bolt on part that works 100%. The machine itself isn't modified. The old one was unscrewed and the new one gets bolted on in its place. The same linkage is leveraged. The only thing that's left to do is make it foolproof. Kit-Kats have flappy wrappers that pose some clogging and catching issues.

Or you could add one of these to your collection :cool: You know one is never enough.

What are the odds that the bar is the same size? That being said, I should go buy a few decades of Kit-Kats, so it works in 25 years for my future grand kids.

No need... just teach the grand-kids your skills and they can make a new feeder when the time comes. !!THUMBSX2!!

Although the key I made worked, I didn't like the look of it, so I did what anyone else would do. Look for blanks on ebay. I found several Yale blanks that looked like they should work, but I wanted to make sure I didn't get a key that was too small. Of course vendors on ebay never post proper measurements and usually they have no idea what callipers are or even own them. So getting dimensions on something like a key where a millimetre will make a difference if the key works or not can be problematic. So here's what I do/did. Fortunately, the seller posted a picture with a tape measure in it. So I can go off of that.

raw.JPG

I take a screen shot of that and drop the image in autocad. Once in there I have a relative scale of what an inch is in the picture. I draw a line on the tape, which should be exactly an inch. Then I draw a line on the thing I want a true measurement of, the key dimension in this case.

unscaled.JPG

If I know that an inch is .279" on the drawing, I can scale that to 1/.279, which would be a factor of 3.58422939. When I do that, this is what I get:

scaled.JPG

The inch is now an inch long and the dimension on the key is .305". I need .275", so this will work wonderfully. I ordered the keys and they arrived today. The dimension that I estimated to be .305" turned out to be .300". A little bit of time with a file and this will be sized perfectly.

I apologize if I did too much of a brain dump there.

I have hundreds of these keys, which was why I asked if you had the code. ;-)

No codes at all on the locks. The only identifiable mark is Yale.
