An update now the worktops are in. Three days of work and I think perhaps an entry in DIY disasters maybe more appropriate!!! The actual joints themselves are quite good, however I encountered three problems when fitting the U shaped worktops.
Firstly, the right hand side - female joint went well. However when cutting to size with a jigsaw this didn't behave and then I had to redo it with a router resulting in the worktop being 10mm too short!
Secondly the side with the two male joints. Right hand side perfect. However I scribed the two sides together and cut them without re-measuring after I had cut the first joint. Result - approx 20mm short! This was fixed by attaching a baton against the left hand side worktop and then glueing the edging strips against the baton and the finish is satisfactory.
Thirdly, when cutting the left hand male joint I did not support the waste sufficiently (and probably left too much waste) and guess what - it fell raway and chipped out the laminate. I managed to glue this back on again to give a satisfactory result.
It is a great shame about these three errors as the actual joints look good.
Thanks for your invaluable advice
