Walls out of square

Masons mitres can be made out of square.

 

Unless you have L shaped corner cabinets, you'll be able fit your base units flat back against the wall as your corner post will allow you to 'pivot' that particular run. You can then scribe your worktop joints. You only scribe the male, cut female as normal. Most kitchens are out of square, but not usually that noticeable. If your work top has excess overhang on that run, you'll prob be able to redo the scribed joint if your first attempt goes awry.

 

Some times you can get away with a little fillet on the leading edge of the L and the straight unit. This can straighten out the run - the worktop overhang and kick boards will hide the slight deviation

 

There's always a solution, like the one Sospan has suggested.
I'd be considering altering the design and getting a corner post in there. Can you rejig the layout and put it in the other corner?

There are other solutions...

 

You can get worktop jigs which allow 85 to 95 degrees Left/Right hand joints to be made.

Yep, I don't like ready made corner units that are all in one piece, for this very reason. As CGN says , consider altering the design and get two units and a corner post.

 

Sorry don't speak "Old Etonian" could someone translate this into English ?

 

You're welcome.
