Thanks gents. The shed was actually build years ago as sort of an entertainment area which I started using as a workshop as there's just no space left in my garage. The tiled floor is a bit of a drawback because its not very flat and my wife still treats the area as hers so she does regular inspections for paint, glue and weld marks on the floor :-)

Have to say I did not realise that building the router was going to this much work! Everything is taking much longer than I thought but I'm enjoying every minute of it. Ahhh well ok not every minute but most of them.
