I bought this tailstock to use with a plain dividing head. Commonly they are used on universal dividing heads, this one is typical of the type seen being sold with some universals.
Anyway, As you can see in the pics it pivots on the front bolt and the rear bolt works in a slot to allow a certain amount of nod up/down. I am just wondering - what is the usefulness of this feature? This is a 5" centre height tailstock but if you nod it up or down not only does it alter the centre height but the centre height also varies as you advance the quill on the handwheel. You might say that it would be useful when using a universal which is also nodded but then if you nod the DH down you'll need to nod the tailstock up and then the points will be even further apart in height difference. Okay, so you might say that one or the other would need to be packed up on parallels but then the packing height would always be different for different length parts and the tailstock does not have a lot of travel. Seems awful fiddly and the tailstocks with two slots seem to make more sense as you can set both height and angle on those.
Can someone please explain the useage of this feature? Obviously, it matters not for my use since it's being paired with a plain DH so I'll set it level and leave it there but I still would like to know.
