Wheel Adaptors for Grinder

My T&C grinder has a very odd wheel arbour (20mm male spigot with



16mmx1.5 thread) and even the UK distributor doesn't have any arbours so I'll have to make some. Clearly concentricity is a key attribute and I can handle that. What I'm curious about is the best wheel holding design. The one that I have has a very odd disc with a slit that I've never seen before. Has anyone else made wheel arbours - what did you do? What's the standard form?

And if anyone has a single loose Coventry die with a 1.5mm pitch I need one to make an external threading tool and would be happy to part with a small amount of cash!



Thanks

What does this slit disc do? My Ward grider has a disc nut to hold the wheel on, this has a slit portion with a socket csk screw to clamp it up, so as to lock the nut in place. This is needed because the spindle is reversible. I don't think the 'arbour' is removable in this case - I've always assumed it isn't

I'll have a look tomorrow - the workshop is closed for the night

I guess that it's to "interfere" with the thread and therefore lock it but there's no screw or whatever - and the spindle isn't reversible!

Maybe (If the slit is similar to that on mine) it's so that it can be crushed slightly so as to make a sort of 'stiff nut' - so the wheel won't undo itself when the motor is switched off?

Sorry, no luck.
