From what I have read the drive adapter is the Holy Grail for these, however, I think a motivated machinist could fab a workable adapter...
 
Interesting, R8 huh? Thanks for response, hopefully OP will concur.
I know a lonely Nichols, free but needs a total refurb, and conceived lots of options for the hand feed cylinder.
I have a super old K&T Universal Horizontal, with some kind of aftermarket vertical head. It swivels and nods, braced by the overarm and doubles RPM's of that machine. It's R8 also.

I have two Nichols Toolroom mills, one of them I completely tore down, cleaned, painted and reassembled. The refurb was straight forward and there is a lot of info on them. I love my Nichols mills. The vertical head is a little clunky to get on and off by yourself but with an extra hand, it is easily mounted.
 
Good to know; have to do everything on my own anyway. You get good practice developing tooling manipulators. With no plans of retirement,looking forward to Day 1 under power. Built up quite the little array, patterned after every toolroom I've worked in. Includes not putting a DoAll 3613 in a corner......
 
Actually, I am very surprised to hear of a Nichols vertical head having anything but an NMTB40 spindle! The one shown in the photo at the top of the thread has a endmill toolholder secured in its spindle by the drawbar with the original Nichols drawbar nut. A little known fact about NMTB is that there are two drawbar threads specified/allowed for each taper size. Nichol's own tooling used the smaller thread size, but their drawbars are reversible studs with each end threaded differently, and the drawbar nuts likewise double-ended.
If I encountered a Nichols vertical head that took R8 tooling, I would immediately look for an NMTB40-to-R8 adapter inside the spindle. Degull, when you get a chance, could you provide a photo of your head's spindle?
 
I’ll be home tomorrow and take a picture of the spindle on my vertical head.
I have only used the vertical head a handful of times. The machine came with R8 collets and I never thought to look for 40 to R8 adapter.

I second the vote for pic, though pure R8 won't surprise me; right angle accessory style (not attached to column) drives are generally compact affairs. Combining a bevel gear train, bearings, #40 spindle and casting will be far larger than possible with R8, and it would probably run standard RPM. R8 gives a different range of potential tooling, even for 2nd op, that era's 40NMTB was still dreaming about.
 
Since NMTB40 collets are pretty rare, an R8 adapter offers a "minimum Z" solution for toolholding on the Nichols (either horizontal spindle or vertical accessory head), where the available Z axis headroom is pretty scanty. For a shop that's not well-equipped with NMTB40 toolholders, an R8 adapter also offers the option of cheaper, more readily available toolholders. But if you've already got a bunch of NMTB40 stuff, I don't see an R8 adapter being very attractive. (Full disclosure: I have lots of NMTB40 and 50 gear in my shop, and not a single piece of R8.)
 
I have a 1953 Nichols mill with the vertical head also. When the literature was printed for these machines, it shows NMTB40. Included in the lit is the factory adapter for 4NS collets. I have that adapter on my mill. The standard set of collets only go up to 5/8” capacity, although I suppose maybe they may have made emergency collets. I have never seen one as yet.

Cat40 tools work in the Nichols horizontal spindle. You need a longer draw bar with 5/8-11 threads.
Agreed. At least half my #40 holders are CAT. No apparent dimensional differences,other than grooved flange for tool changers.
All my machinery has same model tool changer; Me!
 
I've also been looking for one of these, but holy smokes - non-functional vertical head costs more than the entire machine! I hope they made them out of gold or something :D
