Somewhere on one of my puters there are plans for a rotary broach I’ll see if I can track it down it was made and posted by a member on Madmodders.

Great thanks

Here is a design upon which I loosely based my RB. (It is the same that I took a picture of in post #1. Here it is a PDF.)

Here is a video of a fellow (Japanese?) making another version of a rotary broaching tool. Very interesting concept.

His lathe / tools and techniques are absolutely spotless!

Here he shows how to grind a broaching tool using only the lathe.

That as well as clicking on the little YouTube icon in the bottom right worked for me.

Thanks @RobinHood I did not know what a Rotary Broach was till I read through this thread and watched some videos. This Old Tony does a decent job of explaining it too for us less experienced ones.
