I've had a lot of people ask for a build video but if you check out my 15 second typing video in this thread you'll see my video production is really lacking. Given the whole process is 2-3 hours, that's also a pretty long video.

But to answer your direct question, I definitely sculpt the key into its external shape first. I tried the other way around when I first started and quickly gave up.

It might seem like it would be easy to cut too far but this didn't happen once when I switched to walnut.

What worked really well was doing most of the hollowing using the sphere bit in the link below. This handles 75% of the hollowing out and it does so in a very predictable spherical shape.

Problem is, the interior of a Cherry MX keycap isn't spherical. So I then used a reverse code bit square out the interior, this left the walls of the keycap about 1-1.5mm in thickness, which leaves enough room for the switch.
