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

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

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..

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.
