I have an old Craftsman half-blind dovetail jig which I have used for 35
plus years. I keep an old Sears router permanently setup just for this jig.
My router bits don't give an angle, but I put a bevel gauge on one and it
appears to be exactly 14 degrees, so I'm guessing that is correct -- they
are marked 1/2" width, and that corresponds with my owner's manual (which is
available on OWWM.com BTW).
My directions call for 7/16" OD template (collar), and the spacing of the
combs on my jig are also 7/16". The manual says to start with 19/32"
extension and adjust the fit by raising or lowering the bit. I have my bit
currently just a fraction below 19/32", closer to 18/32".
