Put your step tool on a plate. Height measure from the plate to the center line of a chucked cutter.
Next make a 1/2 x 3/4 x 1 1/4" CRS block..(about).. To one side of the 3/4 x 1 1/2 face, ream a 3/8 hole.
Make a 3/8 rod to the 1/16 shorter than length of the height measure. and drill and tap a 10/32 in one end.
Drill/tap a set screw in the side of you block to hold the 3/8 rod vertical with the 10/32 pointing up.
Make a locator 1/4 wide 1/8 thick x 1" long with a hole for a 10/32 screw at flat center.
Grind one end of locator so taking off 1/16 so making your step-tool center line locator when it is mounted to the top end of the 3/8 rod.
You eye ball the cutting edge of your cutter to the locator when your cam is in the fall away position for grinding clearance to a cutter. (just in side the fall away position is best.0
Most often one will butter-fly (back and forth) all the cutting lips in a circle grind fashion.
Then locate each tooth to the cam and grind, bring the cam relief up to just making the edge sharp.. doing same to each tooth edge insures all the lips are spot-on being the same.
