I'm taking a leaf out of the book of a friend who has just sunk a sink unit and a cooker hob into a worksurface - I'm going to start off with a hole-saw bit in my power drill, then will come the jigsaw (just purchased some more blades!) and finally finish with the router.The template is a copy of the original Garrard print on a large sheet of paper. The dimensions are slightly out but it does state what the measurements between centres should be for the mounting holes so I should be able to get it down accurately.
I'm afraid over here in the UK it is not easy to find a helpful pro shop these days :o(
In the fullness of time a picture will appear....
