Cut the lip slot first. Now make a fixture with a flat metal plate (to take the place of the lip). Slide the plug in the plate and align the center of the plug with the center of the plate!
Locate under drill press spindle, drill!
That is also a great way to do it. I have seen the fixture for that. Reel keen. There are as many ways as there is plugmakers. P.

They are overrated. Just looks fancy because they are alum. You can do the same with a nice hard wood. When I get some time , like next winter , I will try and whip up a fixture like the one Bill "Charleston" explained. Paul
