Splice countertops

[jakobnm]

I have several large 38mm walnut slabs that need to be carved for the new kitchen.

I understand that it's common to use connectors that are routed into the underside to join the slabs (I've bought such ones at Bauhaus), and that you also use biscuits. How deep should you route the connectors? I imagine they should be in the middle, so with the center at 19mm deep, to prevent the joint from being unevenly stressed and causing the slabs to lift at the seam.

But you don't usually route that deep, do you? Does it work without problems anyway?

Do you always use such connectors or can you manage by just using biscuits and pressing the slabs together?

hello. you mill the fittings so they don't go below, so to speak. 2 pieces are enough, 15 cm in on each side. if you biscuit joint, make 3 and divide in.

Thank you very much.

Those of you who have failed at joining countertops (maybe someone has), what mistakes did you make?

And is there anyone who succeeded with another method than the one mentioned above, how did you do it?

It would be interesting to hear some experiences on the subject.
