Mechanical Clock Update – 4/12/16

This past week I’ve been busy fabricating my design. The 3D printed parts take a surprisingly long time to print! This is partially because they need high infill for strength and partially since I’m using the “fine” layer setting (0.2mm) for a nicer surface finish. Yesterday finished, cutting all of the wooden parts I need on the BTU lab laser cutter. Despite the nitrogen gas, there was still some burning when cutting the wood. To reduce the appearance of the burn marks I sanded the surface of the wooded sheets with a fine grit sandpaper. I then bonded the wooden layers together with wood glue to create pockets for the bearings. I’ll receive my final shipment of parts from McMaster Carr on Thursday and complete the final assembly this weekend.
