SP3B Medium Pendulum Wall Clock Parts Kit

This kit includes all the non-printed parts for the SP3B Medium Pendulum Wall Clock except for the weights. The STL files can be purchased at https://www.myminifactory.com/object/3d-print-medium-pendulum-wall-clock-142460 and 3D printed on your printer.

The design on MyMiniFactory has two options, the older legacy SP3 design, and the significantly enhanced SP3B update. If you can't decide, I highly recommend the SP3B update. It is easier to build, more reliable, and the parts kit is cheaper. This parts kit is designed to work with the updated SP3B design.

The kit contains all the parts shown in the pictures with a few spares where appropriate.
The metal arbors have been cut to length and deburred.
The flat for the minute hand has been machined.
The bearings have been cleaned and are ready to install. A spare 623 bearing is included.
One heavy spring is perfect for the friction clutch.
The three weaker springs are for the ratchet.
Drill bits for properly sizing the arbor holes are included.

You will need to provide lead or steel shot (BBs) for the weight shell plus pennies or small washers for the pendulum bob.
