This post most likely should be in the blog section, but since the preceding projects was posted here, a number of of you are looking forward to this post of how you can make indexing discs without expensive equipment. the ones I made I had the loan of a rotating table. If you can borrow one go for it. If I had not had loan of it I would never had started to make these jigs, most likely would have stayed with paper paterns, I think it was Duchy that got me thinking about it, htl does fantastic stuff too.
I was surprized that so many of you liked what I was doing, so I thought I had better help you out with a simple way to make these indexing disc. Helped me to as now I am able to make some with odd numbers.
First come up with a paper pattern, a circle divided into the number of segments you want. I entered into the computer under search for an image of the number of segments I wanted, You might find it and you might not. I copyed and pasted the image into a word processing program, adjusted the size. and printed it off.

There are other ways to do this, You could do it the old fashion way with a protractor, or be real modern with a CAD Program, Doing a Search for a program to do that, only one I found was Adobe Illustrator, you can try it out for a month free. That might be the way to go. DOES ANY ONE KNOW HOW THESE DIAGRAMS CAN BE MADE EASILY?

Next center the disc on the diagram, better yet use a compass and draw the circle, may be more accurate, cut out and glue to the disc.

Make a jig with a peg to hold the disc in the vertical position. base should be long enough to clamp to the drill press table.

Then make a clamping board that the height is exactly centered on the disc and pattern. thick plexiglass would be better. Use two bolts and wing nuts for clamping pressure,

Set up the drill in center at the top. you must use a center drill for metal work. If you don’t have one get one an they are very usefull in the wood shop.

You got it now just set the depth gauge on the drill press line up a line with the clamp and start drilling, Very carefully moving and lining up each line so you get a very accurate index plate. If you get a pattern off images, check the spacing, the first one I did was off, The pictures for this post was of the first one and you can see a couple are off. Too bad I didn’t notice that when I started.

This is an easy way to make these indexing discs for the jigs I have posted. Oh by the way mine ended up to be 3 and 3/8 inch. not reason, didn’t measure when I was making them. If I had measured I think I would have made them 3 inches. If you are serious about making these jig or something like them, the following 15 minute VIDEO may help you and answer allot of questions.

Thanks for your interest in these jigs and what they can do. I will do a blog on thing that I learned using these prototypes, and suggest improvements, You may be able to point out some things to then that can help every one.

Thanks for looking and comments are appreciated.

Great how to!!!!!
Can I add for those just getting started that in the third picture you can see where there’s a dowel coming out of the jig, your wheel blank needs a hole in the middle of the circle to fit over the dowel, so drill out your blanks with a hole saw and they will be just right. [You will need to drill out the hole as most hole saws use a bit just a tad smaller than 1/4”].
If and when you start getting into the tread making be sure to stay with the 1/4” hole as other projects down the road will need this for lining things up for hub caps and the like.
I know I’m getting ahead of things but it’s so much fun making jigs for wheels and all.
Again great post.

Thanks Brian.

-- Bob, Western Australia, The Sun came up this morning, what a great start to the day. Now it's up to me to make it even better. I've cut this piece of wood 4 times and it's still too damn short.

Brian, thanks.

Regarding your question

I use Google SketchUp which can be downloaded for free.
the following table gives the degrees for the number of holes. I just divided 360 by the number of holes required. 7, 11, 13 & 14 holes does not give whole numbers for degrees.

Number of holes degrees
2 180
3 120
4 90
5 72
6 60
8 45
9 40
10 36
12 30
15 24

That is a very good way to align the part for each location.
When I needed a 10 hole pattern for the disc I screwed to my chuck. I made it out of aluminum and drilled it in the mill. To get it real accurate, I screwed a steel bar on the front and then put my Wixie box on the bar and turned it until it hit the degree right on the money and I clamped it there and drilled each hole that way.

Thanks for taking the time to post all of this. It will sure help other woodworkers who need indexed parts.
Cheers, Jim

This is a very nice indexing jig. It will be a great addition to your shop.

I’m with Brian. I always use Sketchup whenever I need a to make a template with very accurate angles.

You could also just mount one of these as a gauge for making your indexing wheels. They also have some other cool engineering measuring devices that are super handy.

George_SA comment.

With the rotating table I only got even numbers as I needed to line up the degree mark all the way to 360, fractional degree’s could be done but would take some keeping track where the next fraction of a degree mark would be. Does Sketchup allow you to just choose the segment Number, That way you could get the odd numbers. I looked at it but could not figure it out. Would be nice if possible to do a blog on how to do it. It sounded like Adobe Illustrator you could.

Thanks for supplying the “missing piece”. I thought I was the only one that was concerned about how to easily make this part.
Thanks for all the tutorials and videos on this type jig. I love making jigs.
