Mitering out of square worktops

[TEO]

Hi everyone,

Am I the only one who struggles to get good results when trying to get a masons mitre on worktops that will be out of square when in position?

I dread this process, the square joints are easy with the jig but the angle only has to be a degree out to make my life a misery.

I'm probably just being thick but I'd be very grateful to hear from anyone who has suggestions or a method they've developed to deal with this.

Thanks,
T

There is a way as long as its not more than +_ 1.5%, I researched this quite a lot when doing mine but in the end only needed to scribe one end (female) into the wall plaster very slightly to get a good right angle to cut the male on.

That guy wanted £30 for 3 pegs that you can make yourself or get someone to do it for you.

Thanks Oldman,

looks like a good system, maybe there is light at the end of the tunnel.

You're right £30 is a bit steep for a few bits of nylon.
Why only +_ 1.5 degrees? It would work for the one I'm about to do but just curious?

Thanks again, T

Any other ideas out there?

the 1.5 deg was the figure that kept cropping up as being the max you could go out of square, I didnt get to try going over it so unsure why.

In theory if you cut the female standard, fit the board, get the next and lay that in position against the wall on top of the female with the outer joint edges in line, mark the joint line onto the back of the male part then use the line to set up your jig remembering your router offset from the line drawn you should be able to cut a matching off square male.
