Popular Post Minnesota Oli Posted March 29, 2022 Popular Post Share Posted March 29, 2022 When I took my first camping trip with the new to me Oliver I was thrilled with the experience it gave me, and as I added more trips I started a mental list of things that I could tweak or add to the Oliver that would make that experience even greater. Today's post is addressing one of the items on that list concerning the windows and how they are limited to only being able to be open in fair weather conditions. Because they lean inward at the top of the window they can create problems in rainy conditions whether the window is opened or closed. When closed they have to deal with all the water that runs down from the roof and sidewalls, this can overload the drainage holes in the window frames which can result in getting the bedding wet. Many Oliver owners have installed rain gutters to help alleviate that problem, but there's still the problem of having the windows open while it's raining to mitigate high humidity or that closed in feeling. What I came up with for a solution I'm calling window eyebrows. I created a list of design parameters or considerations that I wanted to hit for this project. The first one was I did not want to alter the Oliver in anyway, that included the drilling of hole to mount the eyebrow to the windows, this really slowed my project down. I'm the type of guy that builds it in my mind before the prototype is built, I went through many different design ideas before I settled on this one. I designed a mount that clamps into the window frame and to spread the load out over a larger area I utilize three of these mount per window. The mounts are inserted into the window frame and the screw on the bottom is tighten which draws down the 5/16" diameter rod in the tapered slot which then spreads the mount to engage the ribs that are formed into the window frame that hold the rubber molding in place. I inserted a still picture in the following video showing that process. To remove the mount you have to take that screw out with the 5/16" rod and there is a hole on the bottom where that same screw is inserted and when tighten it releases the mount. The eyebrow itself is made of 3/16" thick x 5" wide x 29" long aluminum which has 3/4" of the outer edge turn down. I used a neoprene edging trim bought from McMaster-Carr along the length that mated with the Oliver, my hope was that it could be pushed tight enough to seal the water from coming between the eyebrow and the side of the Oliver making for a easy instillation. When I tested this in the rain it looked like it was going to work but after about ten minutes I noticed each window developed a drop of water by one of the mounts and it would fall and hit against the screen about every couple of minutes. So plan B I was forced to use a 1/4" wide weather strip tape between the neoprene edging and the fiberglass wall of the Oliver. There was one more problem, I had to incorporate a drip edge to the eyebrow to keep the water from following around the edge and falling towards the window. This eyebrow is fastened with two stainless steel 1/4-20 button head hex drive screws to each of the three mounts. This makes for a quick install or removal of the eyebrow, Here in Minnesota we had a warm up and it rained one day so that is all the testing I have been able to do, so time will tell if all is well with the design. As far as the rigidity of the eyebrow I'm extremely pleased you can literally grab onto them and push and pull with no flex of the eyebrow.
