Hackaday reports that an individual called Raph needed to reduce the thickness of two foam mattresses for their camper van, from 3 inches to 2.5 inches.
Rather than attempting to achieve this using manual tools, Raph built a low-rider foam cutter to achieve the desired result
The device relies on a 45 inch nichrome wire and is powered by a Volteq HY2050EX 50 V 20 A variable DC power supply, with Raph determining that 15 A was the ideal current for the task.
While the machine works effectively, Raph discovered that polyurethane foam tends to emit nasty fumes when cut using this method.
The article also urges readers to ensure they have sufficient ventilation when attempting a similar task.
