Here’s an interesting homemade tool – a bandsaw-like table where the blade doesn’t move, and is instead a heated hot wire for cutting foam blocks like you would move blocks through a bandsaw. Love it! I’ve made hot wire cutters before but only ever the handheld kind that allow for more freeform movement. This design however is much better suited to bigger blocks or frankly straighter cuts (as long as the side laying down is perpendicular and flat):
Hey guys, I am working on some foam models right now and needed to be able to cut larger pieces of foam so this weekend I designed and built a hot wire foam cutter table.
I wanted to share the process because it’s a really easy weekend project and it cut through 5 layers of glued together foam sheets like butter! You’ll end up with a powerful tool that will help speed up your foam modeling. This version can cut make cuts up to 28″ tall and 16″ wide but you can adjust it to be as large as you want. You can cut horizontally or vertically, it’s easily adjustable with the corner clamp on the arm that holds the wire, and the hole thing breaks down and fits in the base.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
