I have a 6"Junior Bench Grinder like the one you have (it belonged to my grandfather and I am getting it back in useful condition). I am missing one of the nuts that secure the wire brush wheel. Any assistance you can provide as to where I may obtain a nut or the tech specs of the nut (all the stores I have tried sell metric nuts and bolts). Many thanks.
I no longer have this grinder so I'm unable to measure the thread for you. To do this I would measure the pitch with a thread gauge and the major diameter with a caliper. You may be able to measure the pitch using a rule. It's probably an imperial thread so you will be measuring threads per inch. The spindle on the r/h side will have a conventional r/h thread, but the l/h side will have a l/h thread to stop it unwinding under load. Most nuts are available on eBay (I'm assuming you are in the UK) but if I was doing this myself if probably make and tap the nut. Good luck.
Good job, I've just found one of these that I'm about to lightly restore - the nvr is a good idea, thanks.
No problem 👍

Many thanks for the guidance.@@PizzeyTechnology
