A question about Bench Grinder spindle dia.

[Grumps]

Are they standardised. Whilst I'm sure that now they pretty much are, but for how long has that been the case?

We have situations where we have to clean, from lengths of steel trim, decade's worth of paint, rust, and general cr@p.

Currently, the method is to put the item in a vice, with only a sufficient length protuding so as not to induce oscillation, and then use an Angle Grinder Brush, typically,



or



Screwfix catalogue 113, Page 842 refers.

Which, with a small Angle Grinder, works but, is time consuming and, as they wear down, tend to fire off shards of steel wire which penetrate knuckles, often even when gloves are worn.

Therefore, this, A Bench Grinder Brush,


Same catalogue and page. Item 47076, would seem a better alternative. Replace one of the Grinding Wheels with a Grinder Brush and then pass the item back and forth across the abrasive material.

We have two Bench Grinders. In fact, we even have a 3rd on it's own stand but as it appears to be 3 phase, I don't think it has ever been connected. All are of an indeterminate age to the extent that if I examined them closely, I wouldn't be surprised if I found them stamped 'War Finish'. And, yes, I still have some spanners that are marked as such.

What I'm asking is, if I purchased a Grinder Brush, would it fit a decades old Bench Grinder. Screwfix do not stipulate an internal or spindle dia.

Hi Grumps.

No they're not standard, but take a look at Axminster Tool Centre catalog numbers 100486, and 100490 - Supplied with reducing bushes in imperial sizes. Should do the trick.

I appreciate the prompt reply.

When I'm next 'in', I'll have to measure the machines with a degree of accuracy.

I brought one the other day but you need to take guards off and it still catches the main body.also makes it vibrate something rotten , I shall be returning mine

I brought one the other day

I got one of those big wire wheels from screwfix, it came with lots of plastic bits to make the size for your motor's shaft. No wobble at all. only thing the grinder is cheap one and it stops spinning if you press anything too hard into the wheel, but it starts again when you take it out.
Its not ideal but does work well
