Finish for a kitchen counter

[Sgian Dubh]

How should I be joining these two work surfaces? I will be using table buttons to attach them to the frame but I'd like to have a nice tidy join across the mitre (I haven't planed it yet). What is the correct of doing this? Would wood filler suffice?

A kitchen worktop connector would be a good choice, but I'd ditch the mitre idea entirely. You'll be better off making a butt joint between the end grain of one piece into the long grained edge of the other. Your proposed mitre joint will either open up significantly at one end or the other depending on the time of year, or if it stays closed it will cause the two legs of your L to try to move significantly horizontally, or possibly cause the wood to split somewhere. If your counter top was man-made board you could use a mitred joint successfully, but in solid wood you're simply setting up a problem and/or failure for the future. Slainte.

Interesting. I will bear that in mind if/when I re-do the worktop!
