I’m trying to put in a new Dc-Dc charger to support our new lithium bank (blog post to happen when this is all done).
Issue is I need more mounting room. I have decided I need to add a new piece of plywood outboard and next to our starting battery. I made a mock-up of the size of the board and it fits reasonably well. However, I am not very clear on what the “right” way is to attach this to the hull.
For the shelf that supports the battery itself it looks like Ericson just let it sit on the skin, and then tabbed it to the hull. I’m ok with repeating that, but it will make in this case a very small gap that does not allow any access to the hull. It would also mean my tabbing in many places would run over the factory tabbing for the settee which I don’t know if that is great either.
Instead I was thinking of somehow attaching several stand alone blocks to the hull and then screwing the panel to them, but these would seem to have their own issues in terms of how do I make sure they are good enough, the right shape to the shell, and make a single plane for the board. I have considered “gluing” them on with thickened epoxy, but am concerned with making a stress riser in the hull. I recognize that traditional tabbing has give to it that helps.
In all I am probably way overthinking this, but wondering if others have come up with a solution to this issue. I have attached a picture with the panel loosely placed so people can get an idea. It isn’t the final piece of wood in case people start telling me about quality of plywoods, just a mock-up with material I had lying around.
