For the record - this worked absolutely fine. I had a go at moving all three, and couldn't get them to budge by hand, which is strong enough for the ZCI to sit on. It did take about a day and a half for the glue to cure, though - possibly thanks to the cold?
I've previously only used the regular red-and-white Araldite, which is already pretty good - I'm impressed with this blue-and-white stuff, especially considering one side of the join is just a lightly-scarred flat, non-porous surface!
Next up: I coincidentally have a length of dowel of exactly the same diameter as the throat corners (3/4") - it's what I used to draw the corners on the insert before trimming them off - so I'll cut a couple of sections of that to use as spacers to hold the insert up, since there's a much taller gap between the bottom of the iron table and the top than there is between the top of the insert-support shelf and the top of the table.
(I'm actually wondering whether it might be a better idea to leave the gap between the washers and the top of the table twice the size of the gap between the existing cast shelf and the top of the table, so that when making inserts in the future I can double-up the material for half the insert and provide a little extra rigidity.)
