Thanks Greg for the kind words...
Yes I have made quite a few wooden models of trains. I am not sure but I think the number is around seven or eight. My differ from that of the one made in Wood Magazine of course, but models are relatively easy to make, require only a few tools and really just take a lot of patience, time and creativity. The great thing is, you always get better.
I wish I had more time to write, but atlas I am headed out the door to go snowmobiling and thus do not have much time. Still I can leave you a few links regarding some of the models I have made in the past and a rather unique wooden cradle in the shape of a locomotive made for my first daughter Alyson.
As for tools, because you are making miniture pieces of wood, I found a RAS, bandsaw, scrollsaw, sander, drill press are my go-to machines not counting a few powered hand tools. Myself I would make sure you put the models in a case though. This keeps out dust and these things are a pain to keep clean.
Sorry I can't write more. I will try later in the weekend, or feel free to email me. I love to share and am more than willing to share my techiniques to get others involved in this wonderful side niche of woodworking.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
