Great info thanks, I'll glue them in place then. I've only got a small shed other than the room to work in so thought that the laser cut baseboards would help make up for lack of working space and skill...
Hullo Mr Hippo,
I've glued them together but there are already 25mm holes in the end pieces, conveniently enough. Plan was to glue ply behind the hole for the and inset the male former and for the female, glue ply behind and fill the hole with the cutout from the hole and screw it to that so that it sits proud of the surface.
Toggle clamps to carry power sounds interesting but possibly a bit A level for me. I was just going to use connectors underneath the board.
I started this project a little reluctantly on behalf of my lad but as it progresses I'm finding my interest deepens and I'm learning by the day how much of a huge subject this is, an art and a science. So much to learn...
