The angle adapter is similar to the mill drill layout assembly tool with a vernier scale at one millimeter increments and the ability to slide left and right.  But what makes it unique is the angle scale. Instead of a fixed 90 degree spring plunger, it can be set to any angle you choose.  When mounting to the RinGenie make sure the two alignment pins on the bottom of the angle adapter match up to the holes on the RinGenie body.  Then insert the tightening screw and use the supplied hex wrench to fasten it down.

Now let's see it in action. Once the RinGenie is vice mounted we'll move the slider to the desired position, adjust the angle, and tighten it down with the hex wrench.  Once everything is snug we can use the spring plunger to mark our drill point.  Then we'll unscrew the spring plunger and insert the 332nd drill bushing which will guide our drill precisely to that point at the ring at the precise angle we've chosen.
