I think the purpose of the metal sheet is simply to keep the
keyboard from falling out. So any material that doesn't break may
do the job. Doesn't have to have the elasticity of steel.

Are the details of the keyboard somewhere in the
schematics?

Only the electrical connections:

What are the details on how it is machined? Is anyone
else interested in an alternate keyboard?

I'm following your exploits with great interest. I think it will
be important to have keyboard-making skills in the future, i.e.,
to be able to make customized / application-specific variants of
the Ya (maybe the Ben, too, although it has that function keys
row that gets a little in the way of a clean design.)

Those keys would have to be machined "cleanly", so the
distinctive DIY look of your designs would be lost. But the
mechanical principles you're discovering would still apply.

Secondly, what material might I use to make a face-plate for the
Ben? what is on there now is some type of metal?

Do you mean the ~7 x 70 mm strip near the latch ? I think you
can just pry this one off. By doing so, you'll deform it such that
it won't look good if you try to put it back.

But you could then probably glue some plastic sheet with your
design imprinted, lasered, etc., to the spot instead. Or maybe try
a thin metal sheet (they sell them on rolls - it's probably not
too hard to straighten a piece) and engrave/laser/imprint/etch/...

OK, good, I was thinking I was some kind of weirdo. I was thinking that an old credit card would work for the key "framework" though it may be too thick actually. I think I may be able to get some tiny beads at a craft store that may be the right size or close enough. as for making a silicone sheet like the official keyboard features, I'm not sure. But I may not need it.
