Hi,

I bought a 4" 3jaw lathe chuck off ebay, and am adapting it as a 4th
axis for my milling machine. The lathe chuck has a backplate with a
1.5" (1 1/2") spindle bore, and 1-1/2"-8 threads (8 threads per inch)

Is there an off the shelf pipe I could buy to thread into this and put
a couple bearings on the pipe to function as the lathe spindle? I think
I might have to make this spindle on a lathe but it would be nice to
not have to!
