It's about 10 degrees here in MA today, and while I look back at these pictures from the summer I am wistful to say the least. So here's some pictures of some sheet metal work we did on the trailer to patch some gaping holes and button the skins back up after replacing some of the wood inside the walls. Sometimes, when you replace the old rotten wood under the skins, they don't fit back on just perfectly (they would if I wasn't going to repaint the thing, but I am so I wasn't too vigilant about it this time around). There was a gap on the corners of the trailer where the aluminum met and started to separate from the weight of the rear. These gaps had been there since I got the trailer, so I knew I'd have to patch it anyway. First, we put a strip of sheet metal (aluminum flashing for this application - because it's flexible/malleable) around the corner and underneath the member for extra protection. We just nailed it in to the new wood. This would be the flashing that would keep any water out. When you put the skins back down, caulk around the edges and screw it in with sheet metal screws (the ones with the little rubber gaskets work well for this, but we just caulked each spot where the screw would go before screwing it in).
We did the same thing to the spot under the old heater vent, which was a big gaping hole. We flashed with the aluminum strip wherever the skins didn't meet up just right. This will keep the water out.
Once the flashing was in, we needed to patch that huge hole. We used a different type of sheet metal, stainless steel, for the flat panel that will cover this whole mess. See below.
There you have it! We did this on the other side of the trailer where the original water fill was. We didn't match the corrugation of the original aluminum siding because we figured it was all getting painted turquoise and won't be a big deal, but if I was doing a period-specific restoration I would match the corrugation pattern of the aluminum.
Thanks for reading and there's more to come!
