Control motor with Ultimate I/O board?

Using an app to upload a pic... Apologies if it doesn't work.

The pic shows the hacked up drill motor shaft/sprocket, my threaded rod and coupling bolt.  I was planning on epoxying the sprocket bit into the bolt if I can figure out a good way to keep it centred while the glue sets.

Hmm. If you know someone with a lathe, you can have them drill a hole in the center of the bolt, slightly larger than the shaft on the motor, then glue the bolt to the motor.
You can try to drill it yourself, but it needs to be pretty dang close to center of the bolt, and doing it by hand will most likely not do the job.
You may also be able to use a nut, and then some sort of reducer on the motor side. Nut with reducer glues to motor, the long bolt screws into the other side of the nut.
Maybe use that coupling bolt in that fashion?

pixelObsession:
Thanks for the suggestion!

I attached a pic of what I have setting up now.  I'm feeling fairly good about this... I'm going to re-attach the front of the drill to the motor, that will hold onto the bit that will hopefully be "one" with the bolt in about 24 hours.

I probably won't get to the point of setting up a test rig this weekend but I'll update here when I do if it works or not.

That looks like a good way to do it. Does the driver bit go into the motor shaft chuck?

pixelObsession:
Yes, exactly right.

I also realized that I don't really need the pipe part of the actuator if I can secure a pivoting rod to a nut.  And make it take up much less space.

So, the motor will turn the bolt, the bolt will push/pull the nut which will in turn push/pull a rod or bar secured to one side of my lazy Susan bearing.

Hoping to prototype this weekend.
