Finished making a panel (top) for the solar monitor, tank monitor, and switches for the water heater and tank heaters. This panel will be mounted over the galley behind the wall like I did with the
thermostats. The blue switch box (bottom) is for the floor heat elements. It will be located near the floor with a cord coming out that can be plugged into a nearby outlet. The black ABS pieces were CNC'd.
The solar and tank level monitors are held on with screws into 8-24 threaded brass inserts. Due to insert depth, I needed to double up the .120" thick ABS. Pieces are glued together with thin ABS solvent cement. Inserts are pounded in with a hammer. Here is a picture of the back of the panel with one of the inserts installed.
Front of the panel showing the inserts. They are Series 51 from
Spirol West. I recessed the rocker switches slightly.
I noticed when I got done that I didn't quite get the switches centered under the tank panel. -Oops. If this was for a customer, I'd correct that and run another part. Also would have been nice to machine some little areas for switch labels. ...After thoughts.
Below. Components ready for assembly. Next step is to wire up the monitors and switches. Then remove and rework the wall panel.
I can make custom switch panels out of black, white or grey ABS. I even have some extra rocker switches but you'll have to do your own wiring. Please PM me.
