showed a pic of some blocks he made to help him set his drill bit collar depth. This one's for pocket holes but, just thought I'd share. It one of those things I say I'm gonna take a few minutes to make every time I pocket hole but I just finally got around to it.
Its just a simple thing that saves the time required to make it the first few times you use it. The numbers are for material size, collar setting, jig offset from edge and the general screw length.
