I worked on the skids for the movable animal shelter. I completed the one that used 30-degree angles, but it’s rough. I did a poor job matching the angles. I also think the design is too weak. If I hit a rock and the skid has to put all of the shelter weight on one point, I think it’s liable to bust through. I guess the real engineer would do a finite element analysis of the skid and measure the stress. I do not think that would be a good use of my time since the manufacturability of this design is the first problem.
Anyhow, I then designed a skid using only 45-degree angles and lots more supports between the plywood skin. I have not finished it, but it’s looking a lot better. I will probably take apart the 30-degree one and rebuild it to this design as well.
