This is a 'make-it' guide for constructing a DC motor from easily sourced components and 3D printed parts.

The 3D print files are available from GL365A listed below.

The file contains the STL files for 3D printing the base and armature of the electric motor.

Instructions on building this are in GL365.

This guide explains how to make your own soldering fume extraction unit, using a PC fan and some charcoal filter.

You will need access to a laser cutter.

The cutting of metals by means of a plasma arc that produces a high-temperature stream of ionised gas capable of cutting metal. Hand-held torches usually use compressed air as the gas but mixtures of argon and either hydrogen or nitrogen may occasionally be used.
