Wow, you have certainly been a very busy boy!

No slippage expected to be seen on any of those pulleys unless you somehow manage to get them iced up .... none too likely in your climate, hey mate!?!?

So those 3-4 thousand foot coastal hills to your immediate west & southwest actually get reliable snow in season?

Pretty much each year they get a good snow season (sometimes they have to resort to snow makers at night).

Its the 'Man from Snowy River' area -

Well yes, and just a couple of miles further SW from there is Australia's highest peak, but I thought you were talking about just 5 miles West of you, though perhaps you were referring to 5 hours?!?!

In any case, it truly seems you live in one of the most interesting areas Down Under!!!

5 Miles West of me and looking down on us is Pointer Lookout 1564 metres (5,131 ft) above sea level.
Mount Kosciusko (which I've walked to the very peak of) is 2,228 metres (7,310 ft) above sea level which is still only a freckle compared to other countries highest points.
Thankfully no snow for us....which equates to no crowds.

Pointer Lookout (which is thick with deer) -

564 meters is more like about 1,800 feet, but it probably is exposed enough being that close to the coast.

It is 1564 metres (5,131 ft) above sea level.

Things I've learned from doing many now - what works for me.

Lathe 400rpm
Use lots of WD40 and a toothbrush to keep clearing away the chips
Very critical is to have the tap centered perfectly in the middle (spend some time eyeballing this) if there's any chatter whatsoever the tap is either trying ride up or down
Don't put too much pressure on the tap, its not needed and just keep going in a couple of thou at a time. When you're at the depth you want, let the piece rotate at least another 4x for a really clean cut
