Tailstock Offset Tool

[kvt]

the off set center is on a Morse taper how can it turn, trust me i turn taper with this setup

Ok, none of mine have a way to hold the tang, and I have had drill chucks slip, thus I would not trust something else not to slip in it. I can just see it trying climb the tool if I took to big of a cut.

An offset center in the tailstock will not have any way near the foresees that a drill chuck sees. The taper will hold just fine as long as it is clean and dry.

this is what i use, ball center in headstock, off set center in tailstock, just the opposite of what you are thinking

What size ball bearing is that and how is it attached? What do you use to drill your center hole?

the headstock center i believe is a morse 3 taper and the ball bearing is a 1/4" drill and silver solder in , the tailstock is a 2morse. if you have dills slipping in the tailstock you need to re ream it, it must have burrs in it our you are not cleaning it properly. wrap a paper towel around
the center and run it in the quill ,to clean it then inspect it with a light for a burr

Well, the first way it can turn, is that I could seat it crooked when I slam the taper home.

The second way, is if the taper isn't seated right (only takes a bit of oil). The workpiece weight
and any imbalance or tool chatter won't move a simple center, but will torque the offset center.

The third way, is if the taper holds fine in the ram, but the ram key is insecure (or worse, is
only a pin that can shear off). Then the tailstock needs a rebuild. Like mine does...

That center height is a critical dimension, and it's hard to check it or make small adjustments
with the offset appliances we're discussing.
