Anyone know where I can get a live tail stock center with a 5/8" post.
Thinking I could turn things on the faceplate and then place the faceplate on a live 5/8" tail stock center.
I have a live 1"-8 center but can't seem to find a simple way to adapt it to a 5/8" post.
I am unclear at to what you're trying to do.
To get us all on the same page as to terminology.
A - Drive Center - mounts on the 5/8" spindle (headstock) for turning between centers
B - Dead Center - mounts in the tailstock when turning between centers (does not turn)
C - Live Center - mounts in the tailstock when turning between centers (has bearings, point turns with work) #2 Morse Taper
this is more elaborate Live Center that has interchangeable points
The spindle on a regular lathe has threads on the outside (like your 1" - 8 tpi description) but a drive center would mount in the hollow end which would be #1 or #2 Morse taper. and a Live center would not have threads either.
Do you perhaps mean a scroll chuck. (like this)
if so you can get a 1 - 8 tpi to 5/8 smooth adapter from Amazon. https://www.amazon.com/Lathe-Spindle-Adapter-Fits-Shopsmith/dp/B07B4CPC3P
There is also a lathe arbor that is 5/8" on one end and #2 Morse taper on the other, that lets you mount things that normally go on the spindle in the tailstock instead. https://www.shopsmith.com/ownersite/catalog/l_lathearbors.htm
Please, post a picture of what you are trying to do, and/or rephrase your question.
