I have a quey regarding Harold Hall's End Mill Sharpening Accessory from his book 'Tool and Cutter Sharpening'. I should first profess to some ignorance on this matter being new to the hobby. But you people helped me with how to anchor the Grinding Rest adjacent to the Grinder – I used magnets.

The question is: Should I cut a slit in the Bearings as well as in the Front and Rear Bearing supports? These have slits with screws that tighten them up but the bearings do not have slits, as shown in the book. Looking at the general arrangement on Page 102 of the book, it does look as if a slit is there – also, I see from some photos of the device, it does appear as if it is slitted.

Another minor point is that he says to fit the bearings to the Front and Rear Supports 'using two part resin adhesive' – I suppose he means Araldite?

[not done it yetParticipant @notdoneityet]

Can’t say about the slit(s) but I would suggest that Mr Hall was quite astute and used his descriptions carefully. While araldite might be quite satisfacory it is not the only ‘two part resin adhesive’ on the market.

It is akin to someone saying they need a new ‘Hoover’ when they really should really have said they needed a new ‘vacuum cleaner’.
