Hi.
I cut the Guitar out of Sepilia a brazillian hardwood. With the big cutter you can hog out the material. I was cutting 10-12 mm deep in one pass at about 3M / Min.
Typically you can cut a depth = to the cutter width in one pass in Hardwood. With MDF you may want to cut about 75% of the cutter width.
post some photos when you are done
It took about 30 mins a side to machine.
