I have a wall rack of mini systainers holding small tools, machine accessories etc.
I've heavily modified one of these to serve two purposes:
(Right hand side) A low voltage transformer to power my 24V weller soldering iron and other devices
(Left hand side) A digital temperature controller that can switch upto 2.5kW of heating and uses plug in thermocouples to monitor temperature. The main use of this is as a bearing heater using a simple plug in heater element. Bearings heated to 85-90 degrees C will often just drop onto a shaft and shrink tight as they cool. It could equally well be used to warm / preheat almost anything.
Having an "electric aga" in the workshop takes away the temptation to pop them in the oven and risk falling out with the love of my life

Neutrik connectors for mains in and mains out to the bearing heater element.
A proper rats nest inside with wires left loose and overlong plus wago spring clips for convenience to allow me to unclip anything to replace or modify it.

The temperature controller switches power on and off to the heater at a few times each minute so i've used a wear free solid state relay for the heavy lifting. The low power contacts in the temperature controller only switch a few milliamps at 8vDC from the improvised lithium battery pack and this instructs the relay to switch mains at anything upto 40 amps if I'd used thick enough wiring.
Lastly, this toughbox stores a 3kW variac to protect it from dust and damp in my workshop. Neutrik connectors make it easier to use when the variac inside can be preset and left at one voltage for a specific task.
