Just a little extra note:
The WD-40 spray nozzle was chosen because it had a much larger inner hole compared to the other spray nozzles on other lubricant brands I had around.
You need a very thin stiff tube, thinner than a pen inner. I thought that was best.
At 2mt high it still takes a LONG time. I mean about one drop every 5 seconds.
Expect about 1&1/2 to 2 days for each refill. Yes it's a long time, but if you set it up in a garage corner and check on it each morning & arvo when you're about to goto work (example) then it's not much of a fuss.
Enjoy the video!
