Can You Really Duplicate a Very Complex Object Using a Squish Mold?
In this molding and casting video, Robert Tolene attempts something very difficult. He tries to create a mold for an HO scale locomotive body…using a simple squish mold. The body is covered in windows and doors, there are lots of other details, lots of screw holes. It seems impossible.
In the end, he creates a serviceable mold. The casts will require some clean-up, but he’s overall pretty happy with what he achieved.
There are lots of tips in here for how to be successful at something like this. He uses clay to damn up holes in the object, relies on multiple pours, carefully creates gaskets, and he employs the dunkin’ chunkies technique when he runs out of molding rubber.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
