Hi!
I'm planning on building an Osprey 2 and thinking about making it saltwater worthy. The plans have 4130 gear. I know of one flying boat with aluminum 6013t651 gear and would think about replacing steel with that aluminum. Is it a simple mathematical ratio problem? If steel is twice as strong and 3 times as heavy as aluminum, could I just double the thickness to achieve an equivalent strength?
Also, what about the fasteners? I'm concerned about galvanic corrosion.
