I’ve been working on sourcing the electrical parts of the Hot Wire Foam Cutter project and getting them all laid out in the electrical compartment. The goal is to keep the box as small as possible, just large enough to contain all the components.

There are a lot of parts to get into the box. There’s the main variable autotransformer, main transformer, voltmeter power supply, power switch, voltage selector switch, output power posts, auxiliary power output posts, power busses, fuse holder, etc. I’m pretty sure it will all fit into the box as it is, my main concern is how to design and attach the hot wire arm.
I’ve included a small image of the electrical box in this post to give an idea of how the components are getting crowded. It’ll work out, designing in 3D allows me to be more efficient and get all the build dimensions exact. It’s gong to be really awesome to have this thing operational.
