I am in the process of building Harold Hall's grinding rest, along with others as well. I am now also making the grinding head as Mr. Hall described in his book, by using a bench grinder.

I could not yet find a form 11 Norton wheel in Cape Town. Everyone is sold out.

I am now thinking of buying CBN and diamond wheels at Amazon.com.

What grades must I buy? The Aluminium Oxide was 60 grit, but the CBN comes out in several grades. I bought a 150 mm size bench grinder, but I can still use as small as 100 mm wheels.

Guidance here – I think I bought the B91. Note that you don't need a guard all round the wheel as they don't shed abrasive or shatter (being made of solid steel), so you can fit a larger one than your grinder normally takes.

I found that a CBN wheel is significantly heavier than a conventional wheel and I think some grinders would struggle to get them up to speed; Gary uses his Acute setup with an extension which allows hand braking – see his advert opposite.

I have had good results from a diamond wheel from Arc, another of our advertisers, but they were unable to tell me the grit size.
