Thanks for the advice Ian.
The oiler is the one you need. You will need to check the nipples to ensure that they aren't clogged with grease along with any oil ways.
The photo above is of the spindle extension after a clean up and one small modification, the result of a scare. I had a 6" wheel mounted on the extension while playing around with a bit of surface grinding. The motor is VFD controlled and when I hit stop on the VFD, its braking was abrupt enough to cause the extension to unwind. Fortunately no damage occurred. I drilled two holes 180 degrees apart on the extension's rear flange to enable the use of a C spanner to tighten it.

PS On the topic of surface grinding, here's some photos of a simple mechanism to traverse the table. Might provide some inspiration for both of us. -
