The Skirt Assembly
Errors in the First Design
While I'm a reasonably clever designer, my expertise isn't in mechanical design and I don't have a lot of experience scratch building in styrene.This was the major problem that I had with the first skirt design. I used a butt joint where the two pieces of styrene came together. Even using some heavy duty glue, the joint wasn't up to taking any reasonable amount or pressure. Considering that when you lift an R2 the skirt is a natural place for your hands to grip that would not be good. | |
on the original design the joint between the two edge pieces was unsupported except at a rib location | in the revised design the short upper piece extends below the angled piece to support it along the whole length of the joint. |
The final problem I had involves interpreting the BC drawings with regard to the angle of the ribs and the angle that the straight side meets the curved side of the skirt. Clearly what I had here would not work. And you'd have thought I would have caught it in the 3D modeling phase of the design. |
