In this See Jane Drill video, Leah shows how you can turn around the fixed jaw on a ratcheting bar clamp to turn your clamps into a spreader. Some clamps come with a button-release, some have a butterfly screw, some a nut and bolt, but almost all such clamps can be switched into a spreader mode.
In the video, Leah also shows how you can use two clamps to create one large clamp.
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.
