Folks, I'm not a tradesman, just a curious DIY'er... With Kitchen worktops, when there are two bits of worktop to be joined, in a corner, why isn't a "standard" 45 degree mitre used? Why the "fancy" join that needs a jig? I can see that this saves a bit of worktop being needed, (600mm or so), but other than that is there a good reason for NOT having a 45 degree join? Is is inherently weaker, or something else? Thanks, Regards, Simsy
Saves worktop and a shorter join. As a young lad I used to question this constantly. I still prefer them to this day - seems more balanced. A worktop with a wood effect looks better using a diagonal join so the grain flows round. Also, if your corner is out of square by a large amount they give a better finish. Use 4 bolts though.
Ordinary joint done with a jig and router is certainly a lot easier (and quicker ) to do than a full 45 deg mitre joint. If the corner isn't exactly 90 degrees the jig can be offset slightly to accommodate the "out of square" situation. With a 45 deg mitre it's not as easy to get just right.
Yeah, but as that corner gets further out of square you run out of room to offset the jig and those bullnose edges do not line up. But, yes virtually all my mitres are done with the jig - just standard practice. Over the last few years I'm seeing a lot more stone tops though so less mitres to undertake.
I'm sure you have come across them JJ when ripping out old kitchens, Those Alloy strips to join worktops which collect all manner of filth under them.
Ahhh gotcha. Same reason they put kickboards on the bottom of base units,, so **** can build up behind them.
I was always told the reason for not doing a diagonal joint was so the 2 "pointy" bits of laminate at the back of the joint could come away due to surface tension on the laminate?
Hay, I was once a "Council house joiner." (or social housing as they liked to call it) Installed many a kitchen with these abominations. (mainly due to time constraints and cheapness)
