    Okay, here is what I did to get power to the frogs of the switches that were already glued down:

    Here is the frog feeder screw device. It is made from a piece of rail filed to a screwdriver tip with a 1-72 screw and a #22 wire soldered on.

    I got measurements to locate the frog tab underneath, then drilled a 1/2 hole underneath, just through the plywood.

    Take a piece of wire that will fit through the frog hole, push it down through the hole, through the foam, and hopefully it will come on the hole in the plywood. If not, keep trying, or make the hole in the plywood bigger. The wire needs to be pretty close to vertical.

    Make a hole saw from a plastic tube, this one is 5/16" diameter. Place the hole saw over the wire and then start cutting the foam by spinning the tube and pushing up. The wire will help guide the hole saw up to below the frog. When you get to the cork, continue spinning, and use the hobby knife from above to finish the hole and open up the cork.

    Tap the hole with a 1-72 tap, then stick the frog feeder screw device up through the hole, find the frog tab, and thread her on up. Gently tighten the screw and then we'll connect the wires to the spdt switch for routing the proper power and that's it, a fed frog! Use a Dremel tool to cut the screw off flush with the frog tab and we're runnin' trains with nary a hitch!

    Next project is soldering feed wires to the point rails, but that will happen maybe next week.:)

    I started adding jumper wires from the stock rails to the points too. In HO scale, this wasn't too difficult. Someone else was talking about the same thing in the N scale forum. I imagine this would be pretty tough!
