Need Advice.

HI, I have just build this small dividing Head, as in photo. My main gear is 32 gear which is very limited what one divide any work piece, as one can see from photo attached it can be modified to take an extra 2 gears as a train, so that one can have more choice of divisions, my problem since I am not that capable of calculating what kind of gears needed to have at least have some sort of 1/2 deg added to normal division, example to have 45.5 because at it is I can only do a couple of straight divisions.Any help is much appreciated. Thank You
Alf.

That looks like the Harold Hall designed basic dividing head.
Have a look at H.H's description on Dividing Head, Basic where he suggests reading his book 'Dividing' or 'Milling, A Complete Course' for all the information on it.
