My project is to make a 2'x4' mobile cabinet out of 3/4" plywood to store my tools and provide a work surface. First step is to take a 4'x8', using a edge guide use my Porter Cable 3 1/4 hp router to make dado cuts 4' long, on each edge and two slots inside where the inside panels will go. Once the slots are completed, I will cut it into two which results in two 2'x4'. Take another 4'x8', cut them 2'x4's minus 3/8" to compensate for the back panel of 3/8" plywood.
Normally I'd make it out of oak plywood, but its too expensive.
I have a proper size and underside straight bit set from Freud.
A) What speed do I set my Porter Cable VS router for?
B) Is it necessary to cut the edges with a utility knife and straight edge and mask tape to reduce tearout?
