![]() ![]() Before we spent the time to do this we figured we should find out how much weight we were adding, after calculating the total area for the added aluminum and multiplying that number by the weight per square inch of that thickness of aluminum we found it would only add a few ounces, and decided that it was not worth the work to trim them all. Initially, this was concerning because it meant more weight, because of this we considered trimming them all to make them the appropriate size. We had added where we should have subtracted, the result of which was that the legs of the angles were wider than they needed to be. After we cut the blanks and then tried to use the large brake at the chapter shop to bend a few we realized we had done the math wrong for the bend allowance. One of the tools the chapter had was a 48-inch sheet metal shear, this made quick work of the aluminum turning it from a large sheet into blanks for the stiffeners and attach angles for the ribs. During the latter half of January Molly and I did the basic fabrication on the rib stiffeners, I had ordered the aluminum a while back and our EAA chapter had recently finished building a new workshop so we figured we'd put it to use. ![]() Yesterday I spent some time cleaning the shop so I could get back to work so I figured it would be a good time to make an entry on what got done before I last stopped. I did end up with a transfer about a month ago, but it was locally, and then finding the motivation to get back to work was a bit difficult. This entry is a bit overdue, right before I was about to finish the fabrication on the rib stiffeners I learned I might get transferred out of state and put everything on hold until that was straightened out. ![]()
