Motorized spinning grinding head

Now that I've gotten a few other projects done (i.e. refurbishing my new to me Induma milling machine) I decided to design and make the indexing arrangement for my grinding fixture. This first indexing plate I made is for divisions of 2, 3, 4 and 6 which will be the most common for my use. I can make up additional plates if/when needed. I basically copied the design of a smaller grinding jig I got with my tool and cutter grinder that was pretty well worn. So now all I have to do it remove the motor and install the locking pin arrangement and I'm ready to go!

Finished up the last piece of the puzzle... a 3" 4 jaw chuck for the head. I didn't want a 3 jaw, because I wanted something I could dial in exact and a 3 jaw of that quality would have been way to expensive for my budget. Also, for small diameter stuff, I have Jacobs chucks mounted on straight arbors I can hold in a collet.

It sure was handy having a lathe that used 4C collets to make it!
