I think I can guesstimate/grind 55�º instead of 60�º and set my cross feed also...

I got some more done today, along with finishing my taxes...As per popular request, here's more pics...

First pic is cutting the rear sight dovetail; second pic is cutting the front sight dovetail; third is rough cutting the 9mm Parabellum chamber (I use Clymer finish chambering reamer w/high Sulphur content cutting oil; feed in 1/32" at a time, back out & blow chips away)...
