1 review writer said to have been using the very thin coated electroplated version, for about 5 years in his shop, notes that it takes about a months use to "activate" it and that he had never had a good excuse to dress it. Said he did clean the tool before he headed to the grinder to sharpen it, recommended by the wheel supplier I guess. I'll have to make an arbor, and will report on this one when I've had a chance to use it. > On 8 Jan 2018, at 03:24, dave wrote: > > https://books.google.com/books?id=JR-efIBvAH0C&pg=PA274&lpg=PA274&dq > >=CBN+reactivity&source=bl&ots=0CGSHcznFj&sig=9TIF2ZJpkruVX3kTTWtz3erG > >t74&hl=en&sa=X&ved=0ahUKEwjU49rDssfYAhWk3oMKHSBEDrYQ6AEITzAG#v=onepag > >e&q=CBN%20reactivity&f=false > > > > Lots of information to dig thru!
