Mine is still 'work in progress' - I got distracted by the little cap/res/ESR/transistor/diode tester module that arrived from Hong Kong, so I've been building a box for that, and adapting the module so that it can be boxed up rather than used 'as is'. I've had to make a little extender from plastic on the lathe for the momentary push button test switch, and the module has proved a bit more fiddly to mount than I'd imagined at first sight, but it's well on the way to completion. Then I'll get on with the final wiring the the MOSFET meter and the probes. Ridiculous really - I've got two analogue MOSFET meters already, but having been infected by the homebrew virus since 1950, I've never found a cure for it!

Some chipboard has metal in it from grinding up old pallets etc (takes the edge of saws) I don't know the resistivity figures against species off hand but there will be a variation, like you say wood is hygroscopic and if unsealed will take up moisture from the air etc.
That meter will be handy for high impedance valve stuff (AGC circuits, grid circuits etc)
