... topic: 2776 Straight Switches posted: 5 Nov 2015 14:27 from: Jim Guthrie I've just built my first straight switch- I've always used the semi-curved default in Templot up till now. One thing I noticed when constructing the switch if the tight clearance at the heel of the switch. I built a 12ft switch and here's the data for it from Templot 25_050907_580000000.jpg I'm using P-32 (1 :32 scale) and the switch rail length is 114.3mm and the offset to the inner side of the rail at the heel is 3.57mm- all this checked out on the template and on the switch when I built it. The problem is that with a rail width of 2.2mm, that leaves a gap of 1.37mm between the outer edge of the switch rail at the heel and the inner side of the stock rail, which is less than the check rail gap of 1.5mm. So it looks as though the back of the flanges would connect with the outside of the switch heel. I'm modelling the Caledonian and looking at the distance ...
