Time was spent cutting the MLG "rubber" cushion pads that go on the top and bottom of each end of the MLG. This included trimming a bit from the length of each pad, then cutting notches in each end.
This is an extremely odd polymer material; other builders have noted several failed attempts at getting the notches created. I just used a 1/2" sanding drum in my dremel and it basically just melted the notches.
Other time spent removing labels from parts and sanding ;/ cleaning / washing / and priming the MLG in preparation for paint.
