Regulator Physical Installation

The regulator is housed in a two-piece wooden enclosure. The "Wall Dock" screws to a wall or bulkhead; the regulator "Base" (the piece the PCB comes screwed to) then slides straight down onto it and is retained by the joint geometry — no fasteners between the two pieces. Physical installation is four screws through the Wall Dock into the wall, positioned with the printable drilling template below.

Print it at 100% scale ("Actual Size"). Do not let the print dialog shrink it to fit the page.

Printers do not reliably produce true 1:1 output. Before marking any holes, measure the printed template with a caliper or an accurate ruler: hole center-to-center spacing must be 4.742 in (120.4 mm) horizontally and 2.049 in (52.0 mm) vertically. If either is off, fix the printer scaling and re-print.

The template's punch marks are intentionally offset from the Wall Dock's actual hole centers. The wood is machined dry and only expands from humidity in marine service, so the marks are biased to leave most of the screw clearance on the side the wood will grow into. Drill where the template says, even though the screws will sit slightly off-center in the Wall Dock holes at first.

The design reasoning — enclosure geometry, wood movement numbers, and the hole-bias math — is in the Enclosure design summary.
