Old Black and Decker angle grinder with 3/8" screwed shaft. I have lost the sanding disc pad, 5"" diameter. Any hope of a spare or is it too historic?

Hi itforsenior,
Is it the nut you want or a sanding disc pad. I don't use sanding pads anymore, far better to use the flap wheels. Just an idea.

The pad, it was attached by a small threaded disc which is also used to attach a cutting disc. Not familiar with flap wheels.

Sanding discs are old hat, but also depends on what you want to sand. Not sure where you can get a disc, not sure if you could fit a nut from later stuff but they might, some strange stuff goes on with grinders. I have plenty of nuts from old grinders but they would be either Japanese or Chinese. If you can somehow work out thread pitch I could check what is here

I did mention that I need the pad, it is held on by a 40mm diameter steel disc with a female thread. B & D website shows pad not available so I guess it is a lost cause. Thanks for response.

I would have a bit of a look through any nearby old little corner hardware stores - the ones who still have stuff from the 80s that hasn't moved yet. Might have some luck

Norm has made a generous offer here. If you can’t find the parts as Tyler suggests it will be the sort of thing that will need a work around.

Most of the parts for this type of equipment are long obsolete

If it was me I’d work out a way of using the modern flap disks as they are readily available.

The bosses that hold these in place are cheap as the trades that use them often need replacements.

Then you’re going to need a bolt of the correct diameter to hold the boss assembly in place.

I’m not familiar with the threads on these but if you go to a good bolt shop and take your angle grinder in they should be able to match it.

If it’s a common thread then you may even be able to get a stud so that you can use it exactly as the more modern angle grinders are used.

If you know someone with a lathe, the skill and the spare time it would be straight forward to make the parts, however, those skills are becoming more uncommon.
