Although I know the topic of whether or not a miter slot is useful in a router table, I plan on having one in the table I'm currently building. When the location of that slot is discussed, often the defacto answer ends up being "same distance as the table saw miter slot."
While this answer seems to be logical, it's also somewhat incomplete. There's the question of which table saw slot given one's distance is highly dependent on blade (or dado stack) thickness. If I assume we are talking about the left hand slot (in my case, for a left-tilt saw) which is relatively fixed in relation to the cutline (for square cuts), there is still the question of the reference point for the router. Using the centerline of the router will bring the miter slot closer to the cutting surface than on the TS, so any zero-clearance jig riding in the slot would get trimmed by 1/2D of the bit.
So it would seem that a good bet would to place the miter bar slot the same distance away from the outside edge of whatever the most commonly used bit which is probably some sort of straight cutter?
OK, so now for the question, as I've just started building a collection of 1/2" shank router bits (having graduated from the 1/4" trim router world), would folks recommend setting that dimension with a 1/2" diameter straight bit as a "go to"? Would anyone advocate using a larger bit as the standard?
I know its overthinking things a bit, but sometimes overthinking can be fun and I like the avoid the sting of future "head slapping" realizations. Thanks, in advance!
