@Art-Tistic - you should probably start a new thread, as your questions aren’t really related to this thread.
However, to answer some of your questions…
From a post by Ryan:
For the surfacing:
1/2" Dovetail Bit (1/4" shank) Amazon.com
Use @jamiek 's G-Code Generator. It does all of the cutting on a single direction (you choose which direction), so it produces a much cleaner finished product (cutting in different directions can cause the bit to deflect differently, resulting in grooves)
