INDEXER Rotary table
One of difficult things in constructing things is cutting or making circles. Hopefully this will help some of you to invent some new ways of doing things. Adding circles, arcs, or curves to your next project may make it a winner.
This instructable shows you how to make your own indexing table to drill hole patterns, to cut out circles, and to cut many other things related to a circle. It allows you to set the index degrees by setting some push buttons. As an example setting it to four divides the circle in four 90 degree segments. This would allow you to drill a 4 bolt hole pattern or cut an arc 90 degrees in a piece of material.
If I won the Shopbot challenge I would use the machine and software start a small business making signs, templates, furniture, jigs, fixtures, engravings and parts out of wood and plastic. I have put together my own cnc mill drill but feel I need something bigger and more accurate like the shopbot to make it work. The autocad software completes the package for anyone to start a small business. Thank you to Instructables, Shopbot, and Autodesk for a great contest.

Step 1: How to set it
Set the index degrees by dividing 360 degrees by a number. The number is set by using the push buttons to increase or decrease by one or by pushing the increase by ten button.
To set it to 36 push the plus 10 button 3 times and then the increase button 6 times. Note you have to zero the count first by pushing the continuous button or holding the stop button on for 7 seconds. This will make the chuck index 10 degrees everytime the run button is pushed or the proximity sensor is triggered.
Check the count by counting the number of times the indicator light comes on in between pauses.
Run button is used to start the index to the next position or the proximity sensor can be used to trigger it to move to the next index position.
Increase button is used to increase the divide number by one.
Decrease button is used to decrease the divide number by one.
Continuous button allows stepper motor to run continuous full circle rotations. After the continuous button is pushed the run button is pushed to start the motion or the proximity sensor can be used. The stop button is used to stop the motion.
Time lapse mode button is held in for 5 seconds to enable that mode. First you need to set your index step amount. To set to 1 degree indexes first zero your count setting. When it is zero the count light will be turn on continuously. Then push the +10 button 36 times to set the count to 360. Then hold the time lapse mode button on for 5 seconds and the chuck will start to index in 1 degree increments. Push the stop button when you are done.
