Jay, Wow thats a monster for the FB2 -- far too big, flog it and buy something more suitable !
I have the Emco rotary table and the angle plate so it can be used as a dividing head, ?the only downside is it is not possible to tilt it.
?
So I have one of the Brown & Sharpe clones which works well, ?they are OK but not the same quality as the originals but not expensive either and adequate for home shop use. Mine is Vertex brand, there are many others.

Not sure where you are but on UK Ebay there are often smaller quality dividing heads from Senior, Elliot etc look for a 4" size.
