I have to fit this 90 degree corner sink into a 600mm benchtop: http://www.trade-appliances.co.uk/_4056_Blanco_ALA403.html
I have acquired all the kit: Jig & pegs (£32 on ebay), Pro quality 1800W 1/2 router with 30mm guide plate (£15 for the w/e from local hire shop) , new 1/2 x 2" router bits (£15 B&Q). I have managed to complete everything else in this raised floor U shaped kitchen, so I'm game to have a go at this. (With a bit of practise on the old worktops!)
Question is how do I do the join that has to locate under the sink? A 45 degree cut will give me plenty of room for a couple of worktop bolts in the middle and back, but leave the joint at the from with no fixing, except maybe a biscuit.
A 90 cut gives me just enough worktop left to fit a front and rear bolt but it will be only sitting in the 50mm of bench in front and behind the sink.
Whatever I do it looks like I'm going to have a largely unsupported joint right under the sink! A recipe for failure and swelling me thinks. Any better ideas or tips?
While I'm at it, in the other corner, I have an option of a 90 or 45 joint in a uninterupted bench run around a corner. Is there any advantage to one over the other? (except I guess less router bit wear on a 90)
Finally, are bicuits essential or can you just use bolts? (Otherwise I need to go back to B&Q for biscuit router bit)
