Sometime back in the spring I had been looking at getting an indexing system for my shopsmith. During the discussions I mentioned I had a unique method in mind to use for the stationary part of the indexer. I've never seen this approach but wanted to actually make one before attempting to explain my thoughts.
So as promised here it is in mostly pictures.
First a view of the chuck with indexing wheel behind it and a location pin in place. Keep in mind that not all chucks/indexing wheels/pin are the same so this may or may not work for you.
A out of focus shot from the back side showing the adapter which attaches to the quill and sets right up behind the index disk.
This pin comes with the index wheel but I wanted to add a knob before I dropped it somewhere and lost it.
So we can see things better I removed the index wheel and chuck.
It should be clear but in case it is not the adapter rotates to any place around the quill so you should be able to find somewhere out of the way to tighten it down and use it.
Next post will have more pictures....

Maybe I should mention that this idea was the result of wanted to be able to extend the quill and still have the indexing working. This should clear that function up:
No magic here but if you have questions I will try to answer them.

If you wanted to drill holes for spokes in a wheel, this allows for that as well.
In metal work, an indexing wheel lets you rotate a blank and cut gear teeth so that you have a certian number of gear teeth in the circumference.
This design is brilliant and simple, like most brilliant things. The more advanced indexing system have a way of indexing a greater number of divisions in the circumference.
I hope that explains it.

10ERs, other stuff, you know.
definitely very nice work.
the second pic looks like there is a label on the disc.
how about more info on the disk, the chuck adapter, and the indexing disc attachment?
hmm, better add brand and model of chuck to that list of questions, too, I guess.
with all the sales going on this weekend, it might be a great time to pic up the disk and an additional chuck adapter. I am hoping that I don't have to change chuck brands for this to work.

Right now I am trying to tile and lay new floors in my house but then the shop projects are next. Have an old sun machine base on casters I got with a MKVll two weeks ago I going to paint SS grey and turn the top into my SPT stand and then but parts in the cabinet below. Should be a good project.

It looks like I should be able to answer most of the questions by detailing the hardware involved:
The chuck is a Teknatool NOVA G3 (shopsmith use to sell these). The jaws are a mini spigot set (that is what I used to turn the knob on the pin).
This type of chuck uses an adapter to go from the shopsmith shaft size to the chuck size, this portion is threaded and this is the interface where the indexing wheel is captured.
The indexing wheel is a plastic material (I'm not sure how well it will hold up long term). It is a commercial item I purchased from:
As far as videos I don't have any information on them but my guess is that they are out there and a search might well find several.
You can also check the PTWFE I know that shopsmith has at least a couple of versions of indexing hardware in the various editions so that might be a source of other ideas.
You might also what to check your chuck, I have seen some with a hole pattern on the back side which I'm thinking is a built in index plate???
