Drilling holes is easy; humans have been doing it in one form or another for almost 40,000 years. Drilling really tiny holes in hard materials is more challenging, but still doable. Drilling deep, straight holes in hard materials is another thing altogether.
Luckily, these days we have electric discharge machining …read more

If you’re cutting metal in the workshop, you’re likely using a table-mounted cutoff saw, or perhaps a bandsaw for finer work. The power hacksaw is an unwieldy contraption that looks and feels very old fashioned in its operation. Despite the drawbacks inherent in the design, [Emiel] decided to build one that operates under drill power, and it came out a treat.
The build uses a basic battery powered drill as its power source. This is connected to a shaft which rotates a linkage not dissimilar to that seen on steam locomotives, but in reverse. The linkage in this case is …read more

Low-slung body style. Four-wheel drive. All electric drivetrain. Turns on a dime. Neck-snapping acceleration. Leather seating surface. Is it the latest offering from Tesla? Nope; it’s a drill-powered electric utility vehicle, and it looks like a blast to drive.
Surprisingly, this isn’t a just-for-kicks kind of build. There’s actually a practical reason for the low form factor and long range of [Axel Borg]’s little vehicle. We’ll leave the back story to the second video below, but suffice it to say that this will be a smaller version of the crawler NASA used to roll rockets out to the launch pad, …read more

The sergeant🔗 package has a minor update that adds REST API coverage for two “new” storage endpoints that make it possible to add, update and remove storage configurations on-the-fly without using the GUI or manually updating a conf… Continue reading Driving Drill Dynamically with Docker and Updating Storage Configurations On-the-fly with sergeant
If necessity is the mother of invention, then laziness is probably its father. Or at least a close uncle. Who hasn’t thought, “There has to be a better way to do this, one that doesn’t involve me burning precious calories”?
Motivational laziness seems to increase with potential energy, as anyone who needs to haul groceries up four flights of stairs will tell you. This appears to be where this balcony-mounted drill-powered crane came from. Starting with a surplus right-angle gearbox and drum, [geniusz K] fabricated the rest of the crane from steel plate and tubing. We like the quality of …read more

Roscosmos head Dmitry Rogozin, known for bombastic comments, said it was “a matter of honor” to “find the one responsible” for the puncture. Continue reading Russia Space Chief Suggests International Space Station Leak Could Be Sabotage
Never underestimate the importance of fixturing when you’re machining parts. No matter what the material, firmly locking it down is the key to good results, and may be the difference between a pleasant afternoon in the shop and a day in the Emergency Room. Flying parts and shattered tooling are no joke, but a lot of times quality commercial solutions are expensive and, well, commercial. So this scratch-built drill press vise is something the thrifty metalworker may want to consider.
To be sure, [Ollari’s] vise, made as it is almost completely from scrap angle iron, is no substitute for a …read more
