Best place to buy Spindle and VFD?

Ah! That sounds better! And I would agree that 0.5l/min seems a little on the low side. I think a better value would be "a few" - and it's really not that critical, I would think.

Science is great for giving us some insight into what's going on, but a bit of real-world experience helps a lot - like your Perth transformer example. I always remember the story of the physicist who was asked to analyse some data to do with egg production due to his mathematical background. He came up with an answer, backed by pages of analysis and calculation, but qualified this with the proviso, "but it's only true for a ideal chicken in a vacuum!"

As for the original "where to buy?" question, though - that's in the realm of advertising and marketing hype, and no help from science there... My HY inverter and spindle came from a UK supplier who charged a bit more but reckoned that they were reselling kit from a trusted Chinese supplier. That one came with preconfigured inverter, ready to go, and it's been running for about 7 years now with no problems. I've even changed the cooling water a couple of times!

Sounds great:)

"An ideal chicken in a vacuum", I'm going to remeber that one. It's near my bedtime here, but if we're going to talk science and in view of the recent anniversary, my most startling discovery of the last month was that when the Saturn V lifted off the pad back in July 1969 it took the power equivalent to fifty-five modern diesel railway locomotives just to run the fuel pumps!!!!!
As I've always said "Rocket science isn't that complicated. It's just BIG!)
