A spin indexer or a rotary table. Maybe both. Smile

Are you thinking of developing your own software, seeing if Vinny will make his open source, using something already out there?

Just curious as I have all the pieces for this ... Rotary Table Controller ..., just need the ever popular Round-To-It program the PIC and populate and solder the board.

I've decided that my stepper power supply and driver are going into one metal box and the controller will go in another metal box. That way I can change the controller up to something more robust than the PIC if I ever get the urge.

I'm probably going to roll my own. I don't get to program much at work so I enjoy doing small projects at home that require programming of some sort. Keeps me from getting too rusty. That one you linked to looks pretty decent and simple. I don't like the cheap keypad though. This is a Round-To-It project for me also.

Needing to cut some 1/8" internal keyways and not having a shaper, I chose the next best thing since I do have a press.

Good decision.  I bought myself a set as that is what industry uses.  Self centering and easy to control the depth of the key way.

Yeah, a set of broaches has been on my to-buy list for ages. Good sets are pretty high-dollar.

Yeah, that's why I only bought the one I needed. Two handwheels I need to key have a 5/8" hole and I would've had to go to a more expensive set to include that bushing.

Vinny 

What am I looking at the tool, can you give me the link where you purchased it, if handy ?  Want to learn more about this ?

Thanks,
Greg
