Joining Wooden Worktops

[OhGranny]

Hi
I am going to join some IKEA wooden worktops at right angles to each other in my new kitchen.
The worktops only have a very small rounded radius on the edge unlike the large post form radius found on normal chipboard worktops.
Would I still need to use a worktop jig?
I have a router but not sure how deep to make the cut or do I need to use the dogbone slots and the worktop brackets etc.
Any advice from others who have done this before much appreciated.
Thanks
G

think this is more of a butt and scribe,depending on how straight you can cut with a saw then that is 1 way of doing it,or make up your own jig.

how small is the radius.
If very small then do as greggers says. I would cut the straight bit with a router run up against a clamped fence then punch the scribe in with a router bit of the same radius or cut it free hand your chioce..

Hi All
Been reading a lot and got a pretty good idea how to approach it. Still not sure about how to bond it.
I have heard about movement in the joint with the grain of the wood at 90 degrees to each other.
Should I use silicon or glue for the joint or just oil the butting edges and rely on the butterfly bolts to pull it up tight?
I am going to cut a tenon almost the whole length with a biscuit cutter in each face and insert a strip of cut off material.
Thanks
G.

you do not need to cut a continuos grove,i normally use 4-5 biscuits and use poly glue,and it dont move a bit,if your using the bolts as well as biscuits then i would use pva.
