Upper body building

The slate wagon body is simple, and ingenious. First, the sides are dropped into holes in the floor. These needed to be drilled out, although I just waggled a tapered reamer in to make them larger. Lashings of MEK softened the plastic so they would push in. Then, three slats are inserted into the ends. For the middle two, you ease the upper and lower side slats, and then the new one is grabbed by bumps on the end. Again, the holes in the end slats needed to be opened up - a 3mm bit sorted this out. One in place, loads more MEK to bond everything together. All that is left to do, is fit the couplings. Some very accurate ones are supplied, but they won't couple with anything else I own, so time to come up with a plan.
