Mounting blocks for a battery box!
These blocks are cut to fit the hull, and will be permanently adhered in place. Seen here, a work in progress, the blocks are constructed from 3/4″ (18mm) Douglass Fir marine plywood that I had left over from another project and are laminated together with West System epoxy. For added strength, I chose to use 14mm dominos to secure two C-beams, each constructed from four more equal length sections of 3/4″ (18mm) ply. The C-beams and dominos were also set with epoxy. The feet of the battery box will be spaced to straddle these C-beams, and will serve to help lock-in the box to the mounting blocks.
After everything cures, the dominos will be cut flush and the mounting blocks will be sanded smooth of excess epoxy (drips and runs), then another coat or two of epoxy will be applied to get everything all nice and water-resistant. Once cured, it’ll be ready for final installation.
The mounting block will be adhered to the hull with SikaFlex 291 elastomeric marine adhesive, and everything will be given a couple of coats of Interlux BilgeKote (grey).
