As you can see in the photo, it's about a 1/2" dia shaft held in place
by two cast iron mounts at either end, with cast iron caps at either
end connecting to the bobbin assembly and motor rod. The caps are held
in place by about 1/10" dowel pins, which unsurprisingly can't be
pounded out.


Can you lap it in with some fine valve grinding compound?
