The latest DIY ideas, techniques and tools for the manufacture of metal, wood, plastic, ceramic and composites. We talk about machining, using a lathe to machine metals like steel, brass, and aluminium. We make chips fly!
Turns out it’s also possible to drill hexagonal hole using a very similar tool based on the Reuleaux pentagon. The video immediately above, again from jacquesmaurel, shows a tool he describes as a “Vika attachment,” mounted in a lathe, boring an hexagonal hole in a piece of stock. The video below, part of the Wolfram Demonstrations Project, illustrates the process.
The claim of penetrating a razor-blade impresses me, although I note the only metal penetration in the video is thin aluminum, which has been painted, possibly so that it will absorb more light energy. There’s also some cool shots capturing the pulsed-laser’s plasma ball in midair.
Bullet casing, shell casing, cartridge case, pan pipes, flute.
From Home Gunsmith Forum user rhmc24: Using chambers cut off 12 ga. scrap barrels and a new $10 bbl for an Italian auto shotgun, the only other gun part is a scrapped hammer from a 1857 Remington perc revolver. Loads like a SAA Colt but underlever rotates and cocks it. Blow-by is negligible, hardly noticeable […]
“His works look like randomly-generated parts for high-performance machines that don’t work in our universe.”
My “concise” imperative really wanted to call this a bulletproof messenger bag, but I’m quite confident Instructables user Culturespy, author of this interesting (albeit, to my mind, slightly paranoid) tutorial, would be quick to point out that there’s no such thing as “bulletproof.” Writing a free public tutorial about how to build a piece of […]
Via Dinosaurs and Robots come these amazing pictures of a derelict machine shop in the mountains of North Carolina. “No one on the mountain can remember it being open” says the Mondo-Blogo author who snapped the pics. It looked like, one day possibly in the 1960s or 70s, that they just up and closed without […]
