Not novus, I’ve used a little bit of white grease.Have you used novus to lube it ?
Cheers, I’ll give that a go.As far as I know custom rods generally use a standard shaft with the knob bashes off and a new knob fitted. Your problem is probably the olite bearings at each end of the shooter housing. They are a nightmare to change but they are only brass and only less than a cm deep from both ends. So I’d suggest some emery on the inside of the bearings to free it up.
