$18.00 Large Moon Phase Clock

SP14 Pendulum clock with a large moon phase dial, updated for better reliability.
This is one of my largest clocks with an accurate moon phase dial located at the front and center. It is as large as possible while still being printable on a Prusa MK3/4, Ender 3, or Bambu Lab P1S/A1. Runtime is 7.8 days with an accuracy of 1-2 minutes per week. The moon phase dial is accurate to within 1 day every 2.6 years.
The clock follows the same easy to build design style as my other new clocks. The bill of materials has been reduced and the only machining required is cutting the arbors to length. The pendulum components drop into place without glue. The winding key is easier to build and more stable. Multiple size weight shells are provided to allow filling with either lead shot or BBs.
The clock is 9" wide by 22" tall and 6.5" deep (225mm x 560mm x 165mm). The tip of the pendulum is 30" long (760mm).
The minimum printer size is 210mm by 210mm. Total print time on a Prusa MK4 is around 90 hours using 1.7kg of PLA filament.
A comprehensive 50 page assembly guide is included, or you can download it from https://www.stevesclocks.com/sp14 if you want to see the steps prior to purchasing the STL files.

Hi Steve, The plan is to mount this to a piece of marine plywood. The line for the weight will still go straight down and any type of small pulley that will change the direction of the line will be hard mounted to this marine plywood. I have attached one picture of inside this studio (there is 8 total bicycle driven industrial sewing machines each for a designed purpose in making a process for jeans/shorts/workpants. There is also a couple treadle, a hand crank machine, a foot operated kick press, and a lever operated heavy duty sewer (Cowboy Outlaw machine). Basically the board will hide the inverter aircon as it kind of takes away from the human powered theme and I only use it when all the solar panels are powering it...fans are on 4 inch swivels so work fine enough when it is evening. The location for the moon phase clock will be just above the "foot power" painted logo and the pendulum will be right about at the top of this logo. This is why the weight will be diverted with pulley mounted to the board that visually hides the inverter aircon. Your moon clock design will fit in perfectly with the theme of the studio (besides being a bit steampunk it is also a great way to get exercise and stay healthy) Kind regards, Mike
