First off, that is some fantastic work! First, i always keep template on top, this is safer since the cutter is always UNDER the template. #2 I would change those rub collars for bearings,they make them for almost anything,solid collars have a very good chance of burning the wood. Appears you have a 1 1/4 arbor, standard industrial, more accessories for that size than any other! #3 Pin starter is very good, just move fence out of the way. You can put handles on the templates,which is a great idea. #4 Some of your cutters appear to be HSS, it is sharper than carbide but needs lots of sharpening, which changes the size everytime, suggest carbide, you probably will not out live carbide cutters :}:}:}
#5 NEVER NEVER USE THE BACKSIDE OF THE CUTTER!!!!!!!!!!!!!!!!!!!!!! Places for cutters, Grizzly,not the best but for our uses fantastic, Infinity has great tools, FREUD fantastic, They make a spiral bit 3/4 dia with rub bearings on both the top and bottom which cut beautifully. You seem to have a silent but excellent backround from looking at your work. Did I miss anything? you can always PM any questions aanytime.
