Myford dividing head

I just bought a Myford dividing head, on the index plates there are
holes through which the fixing screws pass and a fourth hole slightl
larger (not the bore through the centre) I am puzzled as to what thi
fourth hole is for ?
Anyone know? Sure you do. Davi

No idea but we make Myford division plates [ shameless plug ] in fact ours are better than Myfords as they can do divisions that Myfords can't [ yet another shameless plug ]
Even better is we always have them in stock ready for next day delivery whilst Myfords are still looking for their guide dog [ even bigger shameless plug ]
Having said that I can't answer your question but we do faithfully reproduce the 1/4" hole

better than
Myfords are
the 1/4" hole
I have a strong suspicion that you will find that they use it for location in the jig that they use when indexing and drilling all the other holes.
That makes sense, so may not be right.
