I think your solution is better than mine. Don't sure about temperature volume changes, but initial oil filling should be more convinient with vertical hole. My design of this hole near to useless.
Get the lathe running again and try an under slung counter weight ?

Never think about counterweight upgrade, do you have some ideas? I equipped my lathe by QCTP and it ready to fight
