The plates are 3D "blocks" positioned at the intersections of the rail gauge face and the timber center lines. The plates that have slots angled to accept the rail base are "milled" in situ with a 3D subtract in CAD. The check rails are simply profiles that are "extruded" along the path of the Templot check rails. The only slightly tricky bit is to "machine" the ends with a 3D subtract. Now to ...
