Yes it was Dr Con Tenukest ( sp ? ) from University of NSW in the 1960's
I actually own his old polishing machine , which used to be a Draper configuration - now heavily modified . I can figure mirrors up to 24" on it although rough polishing of 24" is done on a 1 meter capacity machine

You can buy pitch for U.S.39.75 per Kilo from GG but post is dear from U.S.
You can make your own sawdust with a belt sander but would have to make sure there is no grit in it.
