Was the new bit worth it? Oh yes!

Clearly my attempts to save money were a waste of money. I finally gave in and bought a real 30degree isolation router bit on line. 

This may sound stupid but the first observation was how sharp it is - I mean REALLY sharp - this has to be a good thing!

I wound up Mach3, adjusted the z axis zero and went for it. 

Awesome! Perfect cut, no jagged lines as it catches rather the cutting. I wonder if I can reduce the track size ??????

Amazing. The only wobbly piece was in the middle at the top. I had the feedrate set way too high and also the board wasn't stuck down well enough. 

Ok so this needs a little more fine tuning but this is seriously impressive.
