I need to find a substitute for aluminium plate which doesn't conduct

Something like a few layers of the glass fibre used for decent PCBs would
be good - or sheet of that about 5mm thick.

Size needed about 3x2" so small. Load less than a kilo, but supported at
one end only, so a fair twisting moment on it.

Anything I could pop along to a shed and buy?

At 5mm thickness and that sort of size cadging an offcut of Perspex from
your local shop sign makers would be one possibility.

The devil is in the detail so more info would help.

Perspex is a bit brittle. Nylon is tougher but may "creep" if the load
is continous. How much does that matter?

My material of choice would be tufnol

A buy it now of this

https://www.ebay.co.uk/itm/tufnol-sh...UAAOSwcOlal-zV

gives you 5cm x 5cm x 6mm for £3 but he can do you 8 cm x 5.4 cm x 6mm
