Indexing Plates

[nmdeselle]

I have noticed a variety of articles over the years that show how to make your own indexing heads and plates. I am set up for doing the actual work but I don't know what constitutes a set of "standard" indexing plates. There appears to be a standard set of three. Does anyone know if this is true and if so what hole circles are on each plate in a standard set.

Hi
your standerd set is for 3,4,6,12. hole patterns you can make one plate to do a number of things. but the key is are you going to make gears or drill holes with your indexer. if you are going to make gears you need o lot more spaces 36 gives you 10 deg's. so think about what you are going to do with it and remember you can alwas make more plates. hope that help's

Standard set known as Browne and Sharpe set is three plates.
Plate 1 has :- 15,16,17,18,19,20
Plate 2 has :- 21,23,27,29,31,33
Plate 3 has :- 37,39,41,43,47,49

These are normally used in conjunction with a 40:1 worm and wheel.
