So I have to ask... is 1 layer of 1708 adequate for water resistance and strength in non structural components?
I ask because I see mixed responses. I have a tab of 6 inches of 1708 on the bulk heads in the fuel tank area with a full up and over wrap to encapsulate it. All those really do is hold the weight of the center hatch when someone is standing on it and locate the fuel tank fore/aft. I'm considering adding another set for safe measure but they really don't do much.
Second, I should probably do 2 layers of CSM on those side boxes, correct? While not structural, I don't feel 1 layer is enough for adequate water proofing....
Finally, the deck.... This has had me losing some sleep at night but again.... I think it's being over thought. 2 tabbed in layers of 1708 with one going continuously down to the stringers and the other being an extra tabbing layer followed by a top coat of 3.5oz CSM. More than good enough? And I keep thinking I didn't use enough screws but the real strength should be the peanut butter to the cleats and stringer tops.... It's obviously too late to go back and fix if so but I think I'm just "looking" for a problem.... Not working on it is bad. Getting things done makes it easy.
And finally the center hatch supports themselves... peanut butter and then clamping them to the stringers until cured with a tab in on the bottom should be more than enough to support a couple hundred pounds of people walking over it... right? I was thinking PL would be too weak in shear and just laying a piece of CSM on the stringer wetting it out then pressing the support to it wouldn't be strong enough...
Sorry if this seems like a lot. There seems to be a lot of conflicting info on specific things and my setup is a little odd in that the fuel tank remains easily removable. I liked the feature but it honestly seems to be causing me a large amount of stress lol.
