Looking For 90-1 Dividing Head Chart

[Canuck75]

Does anyone know where one could find dividing head charts for a 90-1 rotary table? I have been looking on the
web with little success. I found my original operating book and it has no charts......

I'm entering this conversation late but was recently looking for RT indexing charts and came across this site in the UK that I really liked. Just have to enter your RT gear ratio, indexing hole circles, and ask for a full printout.

You do not need a chart, you need a calculator, the divisions of a circle are infinite, this means that you would need an infinite number of dividing plates for every possible angle, this is cumbersome at best.

I have written a program for the workshop (ShopCalc) and one of the things it will calculate is dividing head solution in several ratios of the worm drive including 90-1. There is an option to print a chart of hole plates, turns and holes for use in your shop.

Download for free or just see what ShopCalc can do.

If you need a chart let me know the gear ratio and the plate holes you have and I will make a printout for you up to 200 divisions.
