I agree with Ant on the use of door-stops. I mount them slightly differently, I screw the bases to the front of the layout and thread each "spring" on to them. I have 1/4 inch dowels cut to the required length inserted into the ends of the springs. These have holes drilled near the tips and a cord threaded through them. I paint the ends of the dowels red as an indication that they're there, don't want any eyes damaged! The advantage for me is that the baseplates are permanently fitted and the springs just screw on when needed. They take up minimal space in the toolbox and are there when needed. I've used them on layouts for a number of years, and remember at Loughborough one year being asked where I got the idea. The late Andy Calvert was next to me so I blamed him, and George Nutter was next to Andy and got the blame from him. I think George actually started the idea.
