"High power tuning caps?"

Wrong questions. Reactive components do NOT dissipate power. Only
the real part of the impedance puzzle, the resistances, dissipate
power. For tuning caps, you're interested in High Voltage, High
Current, and Dissipation Factor, not High Power.

As we seem to be winning the battle in part against the ne'er-do-wells
and their attention-seeking gratuitously abusive personal attacks, what
technical
matters can we discuss today to keep the momentum going?

You can start by eliminated any references to those you allegedly find
offensive. In the midaeval manner, mentioning someones name causes
them to appear.

How about is anyone still making their own wide spaced tuning caps for their
ATUs by
lots of shaped aluminium (aluminum to the Yanks) plates, or has the Cheque
Booker's (CBers)
approach of using auto ATUs taken over?

There are kits available. For example:

Most are used in magnetic loop transmitting antennas, which require
both high voltage and high current features. I haven't been following
the latest in ATU's but as I skim the literature, microprocessor
controlled relays switching capacitors in and out seem to be the
fashion instead of variable capacitors.
