I still don't under stand the need for these nuts . . . press locking pin in, rotate until shaft locked, search around for the pin spanner. Cuss because it's not in the right drawer. Search the bench. Search under the bench. Cuss some more. Check the shed. Nope.. Remember your 'mate' borrowed it, and probably didn't return it like he said he would. Get out the waterpump pliers. Cuss some more. Slip of the nut, cuss again. In desparation stop for a cup of tea. Check the drawer below the one it should be in - there's the spanner - wrong friggin darwer....undo disc thus undoing the nut .
Years ago I saw some fabricators using all manner or cutting discs & sized machined .I still don't under stand the need for these nuts . . . press locking pin in, rotate until shaft locked, undo disc thus undoing the nut . . . replace disc, replace nut, tweek the disc a touch to tighten, carry on using. Very very rarely do I need to use the pin spanner - probably when I've run the disc right down - and then it's that tight, I'd need to stick something through the quick release nut to get enough leverage anyway.
With the proviso I am a DIY user, or a very limited work user, so not exactly going through dozens of discs a day.
It's time to get a new machine ??What if you don't have a lock on the grinder? It's a right faff.
I've got one somewhere in the garage, which is precisely why it's somewhere in the lost section, just haven't used it in years, needs throwing in the bin when located.....It's time to get a new machine ??
I can't think of the time I last saw a double spanner jobby
Got my dad's 4" Black and Decker from the early 80's - and some discs still! But as to the shaft spanner . . . no idea.It's time to get a new machine ??

Be easier to fix the damaged lock pin . . . or buy a new grinderWhat if you don't have a lock on the grinder? It's a right faff.
I have a selection of unused, and very rarely used, pin spanners hanging on a hook by the window . . . I think they get more use winding brake pistons back in, or undoing the grease reservoir cap on my SDS drill.Sorted that for you...
If you haven't already look up the "where's the path" website.Happy day! I just acquired a couple dozen of Ordnance Survey Maps, and others at the local recycling shed. Many cover places I'd be interested taking a bike tour through.

You do realise you can undo them with a standard angle grinder pin spanner too?The dam thing froze up and I had to cut it off with another disc grinder to replace the blade.
Now that looks very useful.I have a few adjustable angle grinder spanners from Temu £1.75 each
I had the lock break on one of my grinders so ground an old open ended spanner down until it would fit behind the disc and hold the flats on the shaft.What if you don't have a lock on the grinder? It's a right faff.
Overkill for 10BA tapping, but handy.....
Only time the spanner comes out is when the disc has disintegrated and locked itself on.Years ago I saw some fabricators using all manner or cutting discs & sized machined .
They all unplugged the power , put a thick glove on , popped the locking pin and used the gloved hand to unscrew the worn or damaged disc , I asked about the discs slipping as they used the reverse process to tighten them up . They said that they never loosened off if nipped up by a gloved hand hand pulling on the disc blade itself .
I've been doing the same for the last 12 years or more using around 50 slitting discs pa ........ till I got my Parkside plasma cutter .
Despite its tough construction it's only 400W .Overkill for 10BA tapping, but handy.....
Injector pump in the background 1st/2nd picture????Picked up a rather nice JayDee tapping gadget for £60.
