Dividing plate for drilling, routing, etc.

Fred in NC

>I just talked to a machinist. He can make a 6" dividing plate out of 3/16" inch steel, precision drilled with 24 holes (15 degrees) on a 5" circle.

The hole will be 1" to fit 1x8 spindles. The plate will fit right behind the chuck, face plate, etc.

24 hole plates are the most useful since they can be used for 4, 6, 8, and 12 sided pieces.

This is the critical part of a dividing setup. The rest, including the arm that has the detent, can be easily made with common hardware parts. It is just a swivelling arm attached to a crosspiece on the bed, like the horizontal part of the banjo.

The other end of the arm needs a pin or bolt to go in one of the holes.

Setting up for a job like this is expensive, so having several plates made at the same time will result in a much lower price per plate.

If there is enough interest I will try to get an estimate based on the number of plates that you are interested in as a group.

Production time will be about 2 weeks.

Best regards,

Fred

Re: Just curioius; why do you need this kind of

Al Crandall

>Why do you need this kind of accuracy? Why don't you make the indexing plate yourself from plywood or masonite? I am in the process of doing this very thing now myself for laying out carved flutes on bowls and platters. I have no way of checking the accuracy of them, but my informed guess is that they will be somewhat closer than +/- 1/10 degree. The great thing about making my own, besides a considerable cost savings, is that if I need a plate for 17 divisions or some other odd spacing, I can whip one up in an afternoon. Won't be as pretty as a machined plate but nobody cares what your tooling looks like, only the finished product.

You are right ...

Fred in NC

>it all depends on what you need, how often you will use it, etc. Sometimes we have to make a decision between buying and making.

>Sounds interesting. Really depends on the price, but I have been interested in coming up with something. So, let us know what kind of pricing we're talking.

>Tony:

I am trying to keep the price at $30 or so. I think I can get it to this price if we get 8 of them made at the same time.

This is for the plate only. The support is real easy to make.

Beall tool is selling them on Ebay

John Crissman

>I have no affiliation with them. I have just seen about 1 offered each week for the past few weeks. They usually end up between $25-30.

>Here is something for you to consider from Bill Johnson.

http://www.kestrelcreek.com/toc.htm?id=22&cat=tech

If you do go with a machined plate, be sure he makes the holes a diameter so a pin that is easy for every one to obtain can be used.

I'd go to HD or hardware and pick up a hardened solid pin, not rolled, and measure it. Have them drilled for it to have a loose fit.

Bill Johnson's homemade indexer

OK !

Fred in NC

>Thank you for letting me know. I had looked in the Beall site, but did not see this item.

It is the same idea... with a few differences.

My design mounts inboard behind the chuck, and the pivot is much sturdier.

I will wait and see what happens.

Bill Johnston's setup

Fred in NC

>Thank you, I am familiar with that site, as a matter of fact, I have talked to him on the phone.

We both live in NC.

I think this is a better design than the one sold by Beall. My idea is the same as Mr. Johnston's, but made of steel, and with only 24 holes, and sized so it can be used on a mini.

I will probably end up making one for myself.

Thanks for posting the link, this way others can see what I am talking about.

>Fred,

Ask you machinist how much it would be to make some of them for 1.25" hole and I might consider one for my Vega. If not, no big deal.

Thanks,

Re: Made one like Bill Johnston's

Danny Wells

>I made one like Bill's except I made it out of 1/4" baltic birch ply. It works great on my Jet mini.

I take a photo of the jig tomorrow and post it here.

I used it to do place the inserts on this turkey call.

Re: Index jig pics as promised

Danny Wells

>Here are the pics I promised. The method described in a recent AAW article for dividing the circle worked very well. That is, make the circumference of the plate in centimeters such that it is easily divided into the number of segments desired. The holes were sized to fit an aluminum nail. Works great.
