Having just started to build a railway in the garden I have just joined the group. As progress in the GR direction is slow at the moment due to waiting for materials. I thought the group might be interested in how some frogs were made for a friend's diamond cross over. The track he is using on his GR is Peco SM32 so the rail for the cross over is IL8 Code 200 which is semi flat bottom requiring the use of chairs. This isn't the only way to make frogs but it works quite well.
First a drawing was made so the angle of the frog could be measured, in this case 13 degrees.
This drawing was replicated on a sheet of 1/8" plywood on which the crossing would be made. No sleepers, chairs nailed directly to the board.
A steel jig of the frog angle was made and about a third of its length was cut away from its apex.
The last 1/2" or so of the rails used to make the frog were bent to match the angle on the drawing.
The outside of these bends were filed down to the web.
The end of this bent portion was cut off and filed to the rail.
The two rails were mounted on the jig and soldered together along with a brass strip that would be drilled to hold the end of the frog to the plywood.
Hope this construction is found interesting, if it hasn't already been descibed in the group before.
Regards Tony.
