Nice job Mike, I've been meaning to try one of these tangential holders. Does it have a side cutting edge angle built in as well, or do you just angle the shank?
Coincidentally, I just posted the first project tutorial videos for a lathe carriage stop and milling a slot like the one for your tool bit was one of the operations covered. I position a smaller end mill on the center of the slot and zero my dials or the DRO, subtract the diameter of the end mill from the slot width and divide by two. That holds position of the slot and gives me a good idea of how much material needs to be removed in each direction. On larger slots, an adjustable parallel makes short work of measuring the slot width.
