I've got the fuse together but didn’t prep a ground lug hole for an aft battery in the left longeron which is nicely primed. I can remove primer but I’m wondering about trying to drill a big hole so close to the skin.
I saw a pic of a bar riveted to the longeron with the bolt hole in the bar. This seems structurally better.
Any thoughts on how many AD4 rivets would carry the start current adequately? Was thinking four or 5 on a short 1/8 bar having a ground bolt tab would get the job done without stripping primer with easier drilling to maintain edge distance on the longeron. Squeezing the rivets would make a good electrical connection in the holes. I wouldn’t prime the short bar.
Suggestions?
