I have been successful at modeling and then constructing transmitter
matching circuits at low power with common sizes of capacitors. Now I
want to move up to the 1 KW power level. Inductors are easy enough to
homebrew but capacitors are both expensive and scarce. Anyone have
ideas or maybe experience in this area?

Thanks, all good info!
The application is to match individual antennas about 75 feet of coax
from the radio. Coax is way too lossy at high SWR's and open wire just
too cumbersome. I have a storage shed with a pretty good radial system
at the feed point. I suppose the best solution would be a high power
remote auto tuner but I am just not ready to commit that much to the
project!

A simple L match should seems the best alternative for the
experimenting. I will slow down until I fabricate/acquire the
necessary capacitors.
