Hi,

I have an old Craftsman lathe (from around 1950). The spindle has no
threads, only a flat onto which the faceplate is attached with a set
screw. This poses a problem when I want to use a bowl turning chuck,
all of which seem to screw on to the spindle. My question is, does a
morse taper exist, which comes out to a threaded section, onto which I
could screw a chuck? Should I take the spindle to a machine shop, and
have threads put on it? Is there another way for me to get a bowl
chuck onto this lathe?

Thanks
