I cheat
This will not work on steel .............
Poor boys way of tapering wood without a taper bar.
I am turning between centers , Dead center in the lathe spindle 4 jaw chuck
And a live center in the tail stock.
I bought a extra tail stock adjusted to 0.200 to one side .
Cutting 0.850 one end 1.250 on the other some times 30 inches in length.
Most tail stocks are not made to be adjusted to the side for tapering .
I use a Ridgid veneer trimmer mounted on the tool post using a router bit
or a 1/4 end mill bit in the router too.
You don't have to get the wood between centers super clamped down as in putting stress into the piece of wood , the veneer trimmers is doing ALL of the cutting and not the lathes rotation <<<<<<<<<<<<
I don't have a photo but you want the wood hitting the side of the cutter not the end for the smoothest cut .
You want to use the auto feed, for any reason you pause or stop the feed the cutter will leave a ghost mark in the wood and its impossible to get out without cutting more wood off.
The best is a taper bar , but they have these too.

My CNC is down right now , as soon as its up I will be using it to cut my tapers.
