Limma kalkstensskivor?

In our extension, we will have space for a deep windowsill, about 24 cm.
I was thinking of buying some limestone windowsills from a 1960s house where they were installed, with a depth of 15 cm.
The idea was to mount the inner one and then adjust the depth of the outer one and glue it to the substrate and to the other slab so the joint is tight.

The slabs have a small bevel, and having a joint doesn't matter. The color difference also doesn't matter. Marble would have been even more beautiful but more difficult with pattern adaptation.

Do you think it could work with a good slab for cutting stone and then polishing?

You will need a fairly large angle grinder, it's not entirely easy to operate one perfectly straight freehand. Practice somewhere else first.👍

You will need quite a large angle grinder, it's not entirely easy to run one perfectly straight by hand. Practice a bit somewhere else first.👍

I'll practice on the parts that need to be removed! I'm thinking I'll run along a guide.

Practice is good 😊
However, I would have placed the cut board on the inside and "hidden" the sawed long side against the window with soft sealant, so that all visible long sides, even those glued together, look nice.
I've cut a bit into old marble window sills and find it really difficult to get really good cuts, even with a small wet saw/table saw. I think(?) it also looks nicer with the wide side facing the room, and maybe a bit more stable if it should have a little overhang. Good luck!

With a handheld saw, it will be difficult to succeed; I would recommend renting a water saw so you have a better chance of succeeding. The problem will be the length to be able to use a water saw.
