Great the Ellis got a lot easier to see for us once you placed it on the mill, we also think if you have to work between a couple of obstacles, it might as well just be a pair of Wilton Vises. Nice brass example results of your #2, 21 plate use on that El Monte, California made (we believe) Ellis dividing head, we only have there 6.00" vise, great share and lesson, we needed that here, always learning.

Great Video. Just bought a rotary table that came with 3 plates. Now I understand how to use it better than any other video I have watched. Thanks guys

You are Lucky to have the chart. But if you don’t, the number of divisions divided by forty is the number of holes you have to move. IE for a 70 tooth gear, 40 /70 would be the number. But there isn’t a 70 hole plate. A 4/7 would work. But wait. There isn’t a 7 hole plate either. Any number that is divisible by 7 will work. It just so happens that 21 is divisible by 7 3 times. The solution then is to use a 21 hole plate, and move the handle pin 12 spaces ( 7x 3= 21, 4x3=12) .Now, if you adjust the wings so there are 12 holes showing, you will move the handle only 11 spaces because you are starting at zero count. Thirteen spaces must show. The edges of the wings are severely beveled to help operating the handle. They should be adjusted so that the pin moves from beveled side to beveled side. In the 14 space example one edge should be against the pin . And 19 spaces around the circle the other beveled edge should be just visible. It is important that the handle is turned in only one direction ( usually to the right) to prevent backlash errors, and maintain accuracy If one overshoots the hole, one must back up and return to that hole from the intended direction. Been using dividing heads for over 5 decades.

I have been told that gears made on a mill with a dividing head are not as good as gears made on a hobber. Can you shed some clarity on that?
@EvolventDesign

From both a quality and cost standpoint, the vast majority of gears are made with the hobbing technique. Milling gears is also done and practiced frequently in smaller job shops when an individual or low quantities are required. As long as it fits the service milling is very acceptable. Hobbing machines have a proven and high quality drivetrain that insures there are no tooth-tooth indexing issues, it is very fast at scale and produces a very high quality gear.

So is this a 6 axis machine
@EvolventDesign

Yes, but it is a very manual 6-axis and the Ellis needs to have the ability to Index, rotate in the X and Z axis. This is why these older indexers like the Ellis are found in most manual job shops -
