[sdiy] Gluing Broken Keys Back Together?

I was going to suggest something along these lines as well. If there is 
enough volume to the keys, use a very small drill bit (e.g. 1/32") drill 
holes into them, squeeze epoxy/superglue/etc into the holes, and embed 
something like a sewing needle between the two parts to bridge the 
actual break point. If there's not (or you're concerned about damaging 
them even further), then reinforcing with a rectangular piece of plastic 
in a non-visible part of the key works too.

It probably goes without saying, but if you can clamp the pieces 
together while the glue is drying, so much the better.

I'm sure it's been discussed extensively before, but it seems to me like 
this is one of the many areas that at-home CNC/3D-printing equipment 
will make a lot easier in the next 10-20 years. Why try to piece back 
together keys (or track down obscure replacements) when you can just 
manufacture your own?
