Ed,

There are programmable indexers that will do what you want. Some will allow indexing
upon closure of a remote switch, so a non-rotating tool could touch the switch to index.
They are not cheap however. MSC carries them. Hass and SMC are two brands that 
come to mind.
You might look into air powered index tables. A bit of scrounging and calling to surplus and 
used machinery dealers ought to turn one up. My previous employer scored one at an auction
for $100. (retail was over 3 grand, but it was a big heavy sucker)
An air valve could be plumbed same as an electrical switch, and just dwell on the switch long
enough to allow a full index. Benefit of this type is that they all use some sort of positive mechanical
lock to hold posision. A good one ought to handle anything you could throw at it.
The one my ex-boss got could be set for any number of indexs that would divide into 24 evenly.
Don't recall the brand name, but  a call to the factory revealed that BIC uses them for pen assembly.
