does anyone have an actual measured diameter of the pad available?

But, just
out of curiosity, where exactly would you order keypads from?
Erik's marketplace right here

They would need shipping to New Zealand which would add to the cost.
Also I have THREE keyboards I'd like to repair not just one.
Oh, I see, these are pulls from another old keyboard. Too bad.
Hmmm...ok, your letter has convinced me. It
SEEMS easy enough, and
it's not like this has to be done immediately. I can snatch a few
hours here and there as time allows. However I'm sure it will take me
more than an afternoon or two so I'm not convinced it's "less trouble"
(-: . More satisfying and permenant in the end though maybe. I'd
certainly replace the foam as most of it is degraded really badly.
I suppose if you could build some sort of circular cutting device that
has the right diameter, it would go a lot easier, but that seems
difficult. You'd need to find a metal tube of the right size and
sharpen it to a blade, then rotate it against foam glued to a
mylar/taped aluminum foil layer. (Or against foam/taped aluminum
separately and then glue.)
I suppose mylar balloons might work if flattened and glued to a thin
stiff piece of plastic also?
At work we have some largish corkborers for
punching out agar plugs.
One of these MIGHT just be a suitable size, which should make the
process a lot easier.
That would work. Perhaps there's some dremel bit sets that would
include this kind of cutting tool? I did find a round cutting bit in my
collection, but it's specially made to cut round holes in doors for
locks. Way too big. But if you can find the right sized tool, or make
the right sized tool it would work. I did mine all by hand with an
Xacto blade, which is a bit boring and makes for rough work. In some
cases the geometry of the aluminum rounds failed to work, etc. But if
there was a tool to get them all to be the same shape/size, it would
work much better.

Something like the above might work, but I'm not sure about the diameter
- the 1" minimum this thing does is too big.
Hmmm, perhaps cutting a tin soup can, then sharpening the edges with a
file and curling it on itself until it's the right diameter on the sharp
end, but makes a funnel on the other end, then attaching the funnel end
into a wooden handle could make the right tool. Problem is the edge
would need to be sharp and that kind of metal is a bit too soft.
I'll let you know how it goes. I'l
probably get onto it in
Mid-January after the holiday season. I've a few family commitments
before then.
Much obliged for the advice.
Sure, anytime. If you do find a tool, or are able to make one, let me
know the details of what worked so I can add it to the FAQ.
