What type of baseboard construction do I use?
I am, without a doubt. One of the worlds worst woodworkers. So getting a square and level baseboard will be a task of Herculean proportions for me. You wouldn't believe how bad some of my wooden baseboards have been, even using 2x 1. I did like using pink insulation foam for my Gn15 layouts and used it to great effect. Except when I had to exhibit the layouts that entailed construction a wooden box or frame for them... That took me back to square one. I doubt that a pink foam baseboard is feasible for a P4 layout. Foamcore board is gaining great favour amongst modellers who favour smaller layouts. Chris Nevards Catcott Burtle is the prime example of this. Perhaps I might be able to use that. I can easily cut a straight line with a Stanley knife and straight edge on Foamcore.
Next up to think about is how to operate the points. After 20 plus years of modelling I have only just got around to electric point motors. When I built a previous EM gauge layout I used DPDT slide switches to change the polarity and both operate the switch rails by means of a wire drilled through the knob on the switch. I liked this, it was simple and easy and not much you could do wrong. Hopefully I can remember how to do that and find a suitable sort of switch over here in Radio Shack.
I need to give these things some thought over the next couple of weeks for tomorrow I'll be down at the post office mailing a couple of orders off for some P4 bits and bobs...
