I made a JT6 taper arbor yesterday before I had to go out of town. I used a .75" piece of plain old cold roll steel, as it was what I had on hand. Will it be usable with, lets say, up to .5" drills? If not at least I know about where the compound needs to be set at.
Thanks,
Ted

regular CR will be fine, matters more that the two tapers are done properly; they're concentric and fit well

Depends how well you made it. Best way to find out is to try it.

I blued the JT6 end and adjusted till I got a pretty darn good fit. The other end is just the straight .75" shaft for use in a collet on the mill. I recently sold my old lathe and threw in the drill chuck that fit in its tail stock. Dumb me, forgot that it was the one that also did double duty in the mill.
