A fuzzy pic of relay doubler but it's better than no pic at all.
Used the HF hole punch set to put four 'optional' lightening holes in the back only of the PC680 battery box. Too hard to do, too easy to make messy, and weight saved is questionable but every ounce counts in the total.
Fabricated the doubler for the gascolator and then oversized the nutplate hole, fabricated another the right way. (Some days should not be spent in the hot shop.) Then finally worked on riveting the relay doubler, and nutplates on the angles. In the end, had to backrivet most of it because it was difficult to keep components 'in contact' when being riveted (leaving a gap between the layers). Had to drill-out drill out 4 of 12 rivets to get it right.
Spent additional time on the web preparing orders for reamers, torque wrench, and a few materials for shop supplies. Also, trying to assemble components in time to keep from waiting on any tasks.
