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

Hacking Broken Plastic Parts without a 3D Printer

We’ve all encountered the odd plastic part that is broken and unobtainable. Sure, 3D printers can print big replacement parts, but sometimes you just need to rebuild a very specific piece. [AkBkukU] shows off a technique for doing just that using a process you could almost call manual 3D printing. …read more

Saving Your Vision From Super Glue In The Eyes

Super glue, or cyanoacrylate as it is formally known, is one heck of a useful adhesive. Developed in the 20th century as a result of a program to create plastic gun sights, it is loved for its ability to bond all manner of materials quickly and effectively. Wood, metal, a …read more

The folks at [NYC CNC] feature a video with a clever hack borrowing from other disciplines. Painters tape is applied to the top of a level mounting surface in the machine and then burnished. The same is done to the bottom of the workpiece. Superglue is drizzled between the tape layers and pressed together so now the stock is held firmly below the toolhead.

Some …read more
