Remaking Old Patents: A 19th Century Hand Plane on a Chisel

Eric of Hand Tool Rescue has been doing a series on his channel where he tries to make/re-make interesting-looking tools he finds in old patent filings.

In this episode, he remakes a sort of 19th century multitool, a chisel that also had a hand plane built into it.

Besides the video being fascinating, Eric includes one of my favorite tips (at 17:41). It’s an old machinist’s trick for finding the center of a piece of round stock by leveling a ruler or flat stock on the vised round stock using a drill press and a bit in the chuck. When the ruler is eyeballed as level, you’re close enough to the center point for many situations that don’t require high-precision. (See below)


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.
