In preparation for cutting those replacement lathe change gears, I had
another little project to do. Some years ago I bought an Ellis dividing
head used for like $20, but it only had one hole plate with it (15-20).
Since I'll need to use the dividing head when cutting the gears it was
time to make replacements for the missing hole plates. With a nice CNC
mill this was a piece of cake:

The plan for cutting the gears is to do semi-CNC, manual indexing then
press cycle start and let the CNC cut the tooth in a suitable number of
passes before stopping for indexing again.

Fun stuff, thanks Iggy!

Well...Im glad you had fun! I guess if I had mentioned I have extra
plates for Ellis heads........


"The ruling class doesn't care about public safety. Having made it
very difficult for States and localities to police themselves, having
left ordinary citizens with no choice but to protect themselves as
best they can, they now try to take our guns away. In fact they blame
us and our guns for crime. This is so wrong that it cannot be an
honest mistake."
