I agree that flake board would not be suitable. However, the material he 
showed is, I believe, OSB, which in the US is called OSB. It comes in 
exterior grades, which are supposedly similar in properties to plywood. 
The OSB dob mount I had was wonderful (certainly much better than the 
particle board ones sold on many commercial scopes), and lasted for many 
years until I replaced it with a lighter mount, as OSB is heavier than 
plywood, which is probably not a big burden for a polishing tool, unless 
it's a very big one.
