I used a standard (name brand from Home Depot) two flute up spiral bit with generic makercam.com settings. The Medium Density Fiberboard (MDF) is probably 100% responsible for the nice finish. People either love or hate MDF, but it does have a few applications where it can be the exact right choice.
-Very consistent, no knots, grain lines, etc.
-Cuts super easily for a nice finish
-Can’t get wet. At ALL! (Bubbles/warps horribly, indoor projects ONLY.)
-Makes actual saw DUST, absolutely requires dust collection, and even then it gets everywhere.
-Heavy, but not as strong as equivalent plywood.
I’m planing on using spray paint for the outside for sure. (Was thinking of doing everything black to get a good finish that seals the wood, and then spraying red/white paint into a small cup and then pouring it into the pockets and swirling it around to try and coat the entire bottom of the pocket. Or perhaps watering down regular paint…We’ll see how that works. If it fails horribly I can experiment with resin. )
