What are the various ways people make their custom cutters?

Do most people make single point fly cutters?

Cut the profile in the outside edge of a tool steel disk on a shaft and notch/relieve multiple teeth into it?

Same idea but starting with a saw blade and grinding it?

Do people build custom machines to grind the tool?

Gearotic really changed that landscape.

All the OLD ways of making gears and pulleys by buying specific cutters or hobs and using specialized machines don't apply so much anymore...

Hi Marc:

  Im lucky in that the gears I make are typically large enough that a fluted bit will
shave them, but I have seen alot of posts from those with slit saws. Not sure what
their using to make the saws.. hopefully they'll kick in. Anything over a Mod 4 or
so is doable with a milling bit.. though slower than a saw.

Hi Marc,

Look here when you have a set of slitsaws, and a cnc machine with 4th axis, You can make wheels from M0.3 and bigger.
