Welcome to Hot Wire Cutting with David and Josh!
David made his hot wire cutter out of PVC piping and extra RC components, including a Turnigy 30A BRUSHED ESC and a servo driver.
You can use building pins to hold down your template.
Hot glue also works on very thin parts of the template. The hot wire will cut through the hot glue easliy.
When cutting you want to allow the heat of the wire to cut the foam. Try not to pull or bow your wire.
This specific project was cut in sections using templates found here.
