Re: [TCML] tufnol whale board for rsg base

[Henry Hallam <henry@xxxxxxxxxxxxxxxx>]

Tufnol is a decent insulator but if it gets too hot from either
thermal conduction or an arc along the surface it will char and become
a conductive flaming mess.  If you're careful it should be OK as a
base on which to mount the stator electrodes for an RSG.

> hi guys, this is my first post.i checked the archives first about the following question but found nothing.i would like some input on tufnol whale board, i recently bought some to construct a 'terry blake propeller gap'i intended to use this as the base 250x250x6mm on which to mount 8 stationaery tungsten electrodes...however..i just did some research (which i should have done first) and found out that according to a suplier it is only suitable for low voltage insulation,i found this quite dissapointing.
