  Disassemble the Macintosh

  First step would be to carefully take the Macintosh apart.  There are some delicate components and high voltage could remain in the CRT screen, so take extra precaution with isolating gloves to be extra safe.  If you are careful and take it out as a unit, not touching connections,  most of it is just disassembly.  Be sure to look for the famous signatures in the back half of the case.  Or by one of the new clear acrylic cases here:  https://maceffects.com/collections/all

  Mounting the Mac to the Mill

  So I struggled with a safe way to hold the front panel of the Mac steady while I milled the plastic away.  I took a scrap piece of shelving wood and under it I screwed it to a 2x4 scrap which will go into the vice.  Then I used the disk slot with a couple of rubber-backed washers to hold the front panel to the board with screws.  Finally I used several wraps of 'shrink wrap', which I felt was cleaner and stronger than tape to really steady it to the board and keep it from moving under the mill.

  Determining Depth of Cut

  As with most of my projects I think I got lucky, but I also believe in allowing your brain to do its job (like allowing your brain to calculate the prefect trajectory to toss a piece of trash into the bin).  A good rule of thumb is to cut a little and then test fit, then cut a little more, as we all know you can't add material as easy as you cut it away.  Since all tablets are flat, we really just need to start by taking the CRT curve out of the Mac opening.  So I started from the low center and worked my way out to the sides.
