Gunner, how rough on the machine is rotary broaching on an Omniturn GT-75,
using 5C collets, broaching an internal 6 point spline of around .312
overall diameter through brass previously drilled with a pilot hole of the
proper minor diameter? How about a larger spline, around .437, through 12L14
Ledloy? The broaching would reach about 3/8" into the hole each part. I
would appreciate any comments you have on this.

Both should be just fine, if wobble broaching. The brass should be a
snap... the larger one may be approaching the limits. Be sure your holes
are deep enough for the broached material to migrate to.

Randy is VERY VERY good and can suggest some speeds and feeds, along
with the proper tooling. He is a sweetheart of a guy and sharp as hell.

Thank you Gunner. This will be very helpful information.
