V-ways to keep that durned tailstock in alignment and tailstock centers with the correct taper (60 deg, I thunk) for pen mandrels.
Legible gradations on the tailstock ram.
I guess that these aren't actually innovations ... just well-known stuff that nobody seems to implement.

And when (or if) that wears out, you can just reposition the shaft another 120 degrees for a new edge, 2 more times. BTW, where can you get HSS shaft in lengths over 6"?

They have stock lengths up to 36 inches in M2 and M42 (sort of an enhanced M4) in diameters from 1/16 to 1 inch in 1 inch. (an example from my 5 yr old price sheet; a 1/4 inch X 36 inches M2, annealed $8.40, hardened and ground, plus/ minus .001", $22.40.) They also have "semi finished" (hardened, unground) for lower prices. If you're doing short bits like for an oland tool, a 24 or 36 inch piece will last a LOOOONG time. :-)
