I have decided to have my cab cut with a CNC router (found a great local company that has good pricing). The 3D plans I have are for 3/4" build material, so I am considering melamine. My plans are detailed enough that I should be able to route the buttons holes, trackball, etc., so chipping should be largely a non-issue.
I searched the forum and it sounds like there is a lot of variability in melamine quality - the coating on some brands is only a little better than paint, whereas others have coatings similar to traditional wilsonart laminate.
I will have to custom order my 4'x8' sheets of melamine, as no local suppliers carry MDF core melamine of any kind. Any brands in particular that I should be looking for?
