The Disabled Guy finally said I could take photos of the progress he's making on his train set. He hadn't let me take photos before, so despite only having my phone on me, I took photos. I didn't want to give him time to change his mind by going downstairs to get my real camera. He's quite proud of himself- and he should be, because he's tackled this task with the same focus and dedication he has for carpentry.
First off, he created the framework for this, an almost-chest-high table with very large drawers and a cabinet underneath. The base is pine and the foundation of the train area is Styrofoam over plywood. The mountains were made from newspaper wads and some kind of plastering agent (he got it at "the train store"). He built the trees by hand, gluing bits of greenery on the little plastic trees. He even went outside and found twigs and dead leaf/sticks to use for his fallen trees. The smaller rocks (and the rocks that will be in the corner) are plaster from rubber molds he bought from the train store. He used the molds as a base, then sanded/added things after it was dry to change their appearance.
And I don't need to remind you that he does all of this one-handed. He wants me to stress- THIS IS IN PROGRESS! It isn't in any way close to being done yet. Also, you should admire his headlight. He thinks he's hilarious by wearing it for model-building. I tried to bring him back to earth by telling him that's one of the intended uses, but he doesn't care.
LOOK AT HIM WITH HIS HEADLIGHT!
Also worth noting, he needs a haircut!
