Hello I am building a layout using peco code 75 electrofrog points etc.Having looked at the Cobra instructions I believe I understand the double slip wiring - each point motor switch control the opposite frog. However I also need a single slip. Is the only easy way to wire the awkward frog to use a frog juicer.Thanks for any advice

Hello Yes I will have plenty of curved sections on a perhaps 1 in 60 gradient. I had no thought of this being a problem since it is my first layout since 1962! John

Hello Thanks for the advice to date. Having looked at Ray's very impressive layout I am very tempted to follow his lead and use 12mm MDF. Apart from a small amount of condensation on the Velux windows in cold weather the room is very dry. I guess MDF does not mind reasonable temperature variation too much, just damp. And 12mm MDF is certainly a good deal cheaper than ply so a bit of wastage due mistakes would not be too serious. John

Hello I am about to start construction of an OO guage layout in a second floor room.It is part of a good quality loft conversion not subject to damp at all and fairly well insulated but subject to temperature variation of course. I have bought some plywood to use for the L-girder frame and legs but am not sure what to use for the track-bed or risers. Will 9mm birch plywood be OK. and if so any advice about how close the supporting risers will be. The width of the track-bed will vary of course some being wide enough for 2 way track and some being wider for 4 track and stations etc. Regards John
