Windowsill in marble or asbestos cement?

[SBH]

The reason it would be good to have the cut surfaces in the middle/as a joint piece is that you get the nice rounded sides on the edges.

I'm wondering if there might be a joint bracket... Or you simply have it as two boards and then make sure to sand and polish properly.

there are those who put the joint in metal

but asbestos is not as dangerous as you think.

It's not as harmless as you think (or want to convince yourself) either. Asbestos should be handled respectfully, but individual exposures will very rarely lead to problems. Among other things, lifestyle, health status, and genetics play a role.

I have placed such limestone countertops next to each other on a common regular window sill bracket, it works well. That is, the ends rest on half of the bracket. Depending on how particular you are, you might think the cut surface you get from hand cutting is quite neat. In practice, no one but you will notice if it isn't perfect.

Then it's just a matter of choosing a strategy:
Either cut them longer, with a straight and neat cut so that they can be joined together. Or, cut them a bit shorter and sand and polish them, and place them with a small gap.

I will investigate if there is something under the window to attach them to.

A small gap is more forgiving, I think.

How did it turn out?

Oh, the boards are still resting outside on the patio. But I'm painting in the living room, so it's slowly but surely getting closer.

Now I've seen how the board was originally placed. It was set too low for flowers, in line with the board visible in the right corner. This long board (2.60 m) was missing when we moved in. I've had a connectable IKEA shelf as a window sill at the right height (http://m.ikea.com/se/sv/catalog/products/spr/89112221/).

The latest idea is to let one board extend a bit past the window into the corner. Not to place flowers on, but perhaps a lamp or something else.
