I want to share here a building started many years ago and, between family issues, movings and other things, stopped and re-started many times. I hope I will be the one who will finish this thing and I'll not have to give it unfinished as a troublesome legacy to my sons... It all started with one of those weekly issues taken in a newsstand... I don't know if you have something similar in your country. Usually is a model very attractive, the first issue is very cheap, the following are not the same... At the end you pay an amount very higher than if you have bought the thing in a shop. But this time was different: I didn't see such model anywhere and, for that I knew, anything similar was available in model shops. So I started... not a good idea... The original subject is a Pacific steam locomotive realized by French engineer André Chapelon in 1909 for the PLM (Paris Lyon Méditerranée) rail company. Here are the issues of the "serial model" and some documentation collected around in the Internet... The construction is mainly wooden but many parts are metallic, so I preferred to put the buiding thread in this section. The skeleton of the boiler and the main chassis are made of plywood The main body is realized by wood strips, like a ship model. A tour into the boiler The rear section is made the same way.
