Taper setup with a boring head

[Christophe Mineau]

I think it is Marv who is the precursor of this method for turning tapers on the lathe using a boring head in the tailstock.
Many thanks to him for this clever idea !

I wanted to give it a try in order to turn some taper mandrels that I needed, and I decided to make some accessories to it :

A small live center with cylindrical shank that will fit the boring head :




It's made of a stack of a bearing stop and a couple of ball bearings



A pair of spherical centers, re-using the ball tool I already showed yesterday.



And also a couple of Lathe Dogs, two different diameters :




And here is the complete setup :
Turning a reference cylinder :

Offsetting :

Turning the taper :

And finally a shearing tool showed here to finish the cone. (This tool is really wonderfull !)
