Test track Safe-T

The test loop is setup temporarily on top of my Work Mate, and to help prevent it from being accidentally knocked off I've added a safety cleat. 

It's made from 2 pieces of scrap 1x2 pine screwed together to make a T. 

The T slides into the hole in the centre of the test track board, and is then clamped between the Work Mate's jaws. The board is a little wobbly as the foam underside needs a bit of flattening - or needs a shim - but locos run fine, and the T does stop the board from being bumped on the floor.
