Crunch.
It does look a bit uniform to be pure decay though. I'll just fill over it from both sides.
At least glue a coin or something in there before you start slapping filler in.

Top idea. Think I've got some pre euro shrapnel.

Assuming the back of the hole is hidden the best way to patch that is to glue a patch of something non-ferrous to the back of the hole using jb weld or similar then fill the hole up from the outside. If you wanted to fill it the traditional way you could used lead or plumbers solder but I would use isopon P40 glass fibre filler to fill up most of the hole then a thin skim of your std filler for a good finish.
It might be an idea to treat any rust with a converter solution like rust remedy or just use phosphoric acid as it's the active ingredient in those 'magic' solutions! It can also be found in alloy wheel cleaner in a weaker form.

Today I got the new pulley. The old one said 4" on it, but we measured it at the shop and it was actually 3.5". That saved me $7, happy!
It's also much better built than the old one which was extremely thin. This is chunky and nicely machined.

I was moving a few things around and noticed the buttons on the switch had rotated 180 degrees. Not one to let things like this pass by, I set out to find a solution.
I decided to cut a key in the cast. This old cast is tough stuff, even with a good quality file it took a bit of work, especially as I had to do two.
I had plastic rail from a model railway project left over, so I filed flat one side, then the box channel was carefully filled with epoxy resin and aligned with the keyway.
And here we are - buttons back in, cotter pins replaced and now the buttons won't spin when they're pressed

Made some little progress today. I had a root through all the bits and found a few things which wouldn't present too much work to tidy up.
The first was the brackets for the guards, I did one. I used a sharp chisel to get the paint off, it's so thick it curls right off, very pleasing actually! These brackets are welded, I was surprised - they've done a really nice job unlike the spattered balls of slag that hold the Colchester cabinet together.
The other side shows the tell-tale signs of grease having been used instead of oil where the washer goes. What is it with schools using grease on everything?
Then I turned my attention to the hub cap which goes on the left hand side, joining the two castings together for the water trough. This is a steel band with a tin (I think) cone and cap, which is soldered.
I'm using the wire-brush wheel in the grinder to remove it; as soon as it hits the wheel chunks start ripping off which is great. The whole thing is a bit dinged up so I'll need to hammer them out before I repaint it. Think it'll need some filler on the join. I will be glad when all the filling is over!!

Grinder was taking ages with the wire brush wheel so I used the linbide scraper which worked really well, dislodged the paint in sheets. This piece has a shade of red not seen anywhere else on the machine. That's eight different colours so far, including the original.
This is clean now
I can also decorate cakes just so you know
And finally a sand and gush over with filler primer. Some small imperfections will need a very slight fill, sand and re-prime but otherwise that's 63 years of use turned back to day one.

Something small to show you. I've been chipping away more paint today and fettling castings, but to be honest it's all a bit same-y if I keep posting strip-fill-sand-prime photos, so here are the guard holders.
The left hand side has taken a smack at some point. I'll give it a squeeze in the vice and hammer out what's left
'C'mon guys we've got ten minutes to repaint this thing'. It was reassembled wet so all the parts are stuck together and rip apart when they're dislodged.
And back in normal town, the right hand holder is looking resplendent in grey with the bare metal arms.
I was also going to do the guards themselves today. If you remember one was dented, that is now sorted out, but sheets of paint cracked off so I felt like a go with the linbide scraper to get the rest off. It was going well until I noticed something under the paint - a painted over transfer, which I had just ripped off with the scraper. I was annoyed, but hoped that if I carefully used the linbide on the other one and used a craft knife, I could peel the paint off and reveal it. Happily, there was one and the strategy worked a treat!
I really want to make a replica but I'm useless at both PS and Illustrator, @dazza might you be able to help? There's no particular rush. I had a go myself on Paint but it looked terrible.

Baby steps, ground the table of this flat then chipped off the old filler, sanded and refilled, primed and then filled the small defects and pits with knifing putty.
Filler primer round two, looks lovely and rounded
And I even got a layer of topcoat on within the day. I'm happy with that
One more piece down. I think I'll tackle the two 'shade' things next which go over each wheel guard. It's become obvious I do not have enough filler or primer to keep going with the body so I'm doing small stuff to use up what I've got. I was thinking of doing the water tank, but I've found it to be very handy for storing screws, it even has its own lid!

These things are next. They go on the wheel guards and droop down. Of course they could have been made from sheet metal but where's the fun in that when you can make them in cast iron... Here we go again!
The near one is actually larger than the other by about 5mm. Not entirely sure why. Both have filler on, of course...
The naughty students have had fun pushing the guards into the wheels. I'll probably use stripper and try to scrub the paint out from in here, can't wait for that lovely job.
I will be using one of my other grinders to grind this casting back a bit. I thought it was caked paint at first.
The plan is that once this is up and running I will be able to sell one of the bench grinders, probably the Selecta. Funnily enough I almost sold it before I bought this one, but the buyer 'didn't notice the pickup only' notice, and the sale fell through. Good thing really as it's been working non-stop the past week cleaning bits for its big brother!

Whilst the twins are in the vice getting chipped clean, I finished off the painting of this guard today. Although I'd done it before, I just wasn't happy with the join between the cone and the band - it's a lap join on the underside and there was too much of a trench for my liking. Took a few goes of filler and a lot of sanding, primer etc but now it looks pretty good I think.
Also saw to the little table on the other side. This moves and I didn't think it was worth filling it as there was so little that needed doing. Here it is in primer which I'll leave to harden overnight then paint in the morning.
Cheers

Couldn't you remove the paint with a gas torch?

Just out of interest. Can the motors be changed on these type of grinders.

Absolutely. No reason not to, except that you'd need to get the ratio right. The motor is 3ph 2850rpm with a 1.5" pulley on it going up to a 3.5" pulley. I was thinking about swapping the pulleys and using a 1ph 1425rpm motor which would still get me the right speed but I'll just go with a vfd because I'd like the speed control for sharpening chisels in the water fed wheel.
There's a lovely one in Stockport for 250 quid, almost totally original looks in very good nick on eBay right now.

From my internet research it seems the earlier ones had a bigger base than the later ones. The later ones also don't have the nice grilled sides. I've seen a few 'restorations' with an oversize motor hanging out the side of the casting

One coat of topcoat on the cone, unfortunately there's a drip so I'll wait a week and then sand it out, repaint accordingly. Here it is in place showing the rest of the machine up!
Here's the right side arm, this holds the little table. Pretty much a big, bone shaped lump of cast that needs filling.
Talking of which... I was browsing TradeMe for spot putty today and 3M was $21 reduced from $50 (apparently - is the tube gold lined?). Then I found a company called Novol who were offering a tube for $7. Anyway long story short, I checked the postage on the shop's TradeMe page and on their actual web page, and not only were all the items cheaper but on the actual page they did combined shipping. I now have 3.5l of easy sand filler, a set of applicators and a tube of spot putty coming, all for $50, when at the shop I usually go to (big auto chain store) 1kg of putty is $39. With any luck I'll have enough left over for the lathe.
The lathe cabinet is actually really useful as a workbench, if a bit low. The water feed system is cast. No clue why, this could easily have been made (and probably would have been cheaper) out of a pressed steel tin like a fuel tank on a stationary engine, but no, cast iron all the way.
Big thanks to @eLuSiVeMiTe for putting me on to using linbide scrapers, I'd used them on walls before but they just tear through paint on cast like no tomorrow. I make great progress!
More parts take their turn in the primer. The inside of the reservoir is rusty bit I'll probably leave it be. I might give it a sand, but it'll only happen again and it's not structural.
Tomorrow I will hopefully get that guard holder into topcoat and try to reassemble the guard arm for it too.
