No glue required: Wood and metal bonded with sound and 3D printing

Manufacturing could be dramatically changed thanks to two new techniques for joining materials created by scientists in Austria. The two methods create super strong bonds at the pore level, eliminating the need for caustic adhesives.Continue ReadingCat… Continue reading No glue required: Wood and metal bonded with sound and 3D printing

Workholding Options for the Beginner CNC Operator

A person putting a screw into a CNC spoil board on the left of the image. Their drill is chartreuse and black. Clamps hold a rectangular board down at all four corners. The spindle of the CNC is just visible on the right hand side of the image.

Designing a file to cut on a CNC is only part of the process. You also have to keep it in place while the machine does its work. [Garrett Fromme] …read more Continue reading Workholding Options for the Beginner CNC Operator

Plant-based glue bonds even better when placed underwater

Getting glue to stick in dry conditions is relatively easy, but having it maintain a bond underwater is much more difficult. That said, a new bio-based glue not only works underwater, it actually gets stronger when immersed.Continue ReadingCategory: Ma… Continue reading Plant-based glue bonds even better when placed underwater

New adhesive can be switched on and off on demand, even underwater

Scientists in Japan have developed an intriguing new glue that can basically be switched on and off on demand. The adhesive sticks together when hit with one wavelength of light, and breaks apart with another, allowing it to be removed and reused easil… Continue reading New adhesive can be switched on and off on demand, even underwater

Mussel-based glue helps stem cells stick to their job site

The utility of the humble mussel in the world of medicine has expanded once again. This time, researchers figured out how to use a mussel-based glue to hold stem cells in place long enough to repair cartilage inside a rabbit’s body.Continue ReadingCate… Continue reading Mussel-based glue helps stem cells stick to their job site

Exploring Woodworking Mysteries with Strain Gauges and Raspberry Pi

If you’re not a woodworker, you might not have heard of the “45-degree rule.” It goes like this: a clamp exerts a force that radiates out across a triangular region …read more Continue reading Exploring Woodworking Mysteries with Strain Gauges and Raspberry Pi

Powerful new adhesive stays strong from freezing to boiling temperatures

Researchers from China have developed a powerful new adhesive that grips strongly in extreme temperatures, from the deep freeze of liquid nitrogen to the sweltering heat of an oven. Better yet, it can be broken back down into its component parts and re… Continue reading Powerful new adhesive stays strong from freezing to boiling temperatures
