Panavise is a popular tool with hobbyists, particularly for electronics. However, it can take many knobs turns and a lot of time to open and close the jaws.
This Instructable shows how to quickly open/close the jaws with a power drill or power screwdriver (which you probably already have) via a coupling nut attached to the vise screw. Watch the video to see it in action.
Since the Panavise screw is a standard 10-24 thread, a coupling nut should be readily and cheaply available from your local hardware store. Attaching the coupling nut should only take about 10 minutes.
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.
