[quote]The plans in GR has 2 strips of wood underneath that run the length of the switch to give it strength. On my layout I have all my switches on patio blocks that give them a solid base and helps to keep the dirt out of them. The placement of the switches I want to build will be on a elevated bench where a yard will be located so I can’t do the strips but I was thinking about a piece of thin plexi to keep them rigid.

Todd,
I’ve made a few switches in my time, and I agree with all that has been said here - especially the bit about satisfaction. Once you have some confidence, you can build a 3-way or curved switch that will uniquely fit your railroad but can’t be acquired commercially.
The battens/strips underneath hold the ties in place while you are making the switch - until you attach them to the rail there is nothing to stop them moving. Once it is done, they can be removed (although some strength will be lost.) You could make the switch on a flat piece of plywood using double-sided tape to hold the ties in position. Or use plexi.
I have plans for a variety of switches, including D&RGW ‘official’ drawings, showing the number and sizes of the ties. But they are ‘scale’ drawings, and if you want it to match your existing track, then (as suggested) copy an existing switch.
