I could tell you how to use the apron handwheel but then I would have to kill you 
Pity about the being killed bit
because some of us, well me specifically, do need to be told how to use the handwheel.
Having recently graduated from a Unimat with a lead-screw dial graduated in 0.05mm divisions and the topslide only actually fitted for taper turning, to a 10" swing Logan (which will happen just as soon as I have managed to clear enough space in the garage to get it erected) I am wondering how accurate horizontal positioning is best accomplished on the bigger lathe.
Because not only is the apron handwheel not graduated, but it also runs against a relatively coarse rack. So I would assume that the top slide is the correct method for horizontal tool movement. But so many photos show the top-slide set to what would appear to be some random angle making the graduations pointless that it would seem that there is another way. So I was wondering without a lead screw handwheel, what is the recommended method of horizontal positioning?
Thanks,
