“World’s Smallest” Working V-12 Motor
A Spanish craftsman named Patelo skillfully designed and fabricated this tiny working V-12 motor from stock stainless steel, aluminum, and bronze for his grandchildren Sara, Carmen, Jose and Pablo. It took more than 1200 hours of work. Not counting the 222 screws, he machined all 261 pieces himself. The engine operates via compressed-air injection, has 12cm3 total displacement, 11.3mm cylinder heads, and a 10mm stroke on each piston.
Building the MakerGear Mosaic 3D Printer – Part II: The Y-Axis
This is the second installment of my series on building Rick and Karen Pollack’s MakerGear Mosaic 3D printer. This part covers assembly of the robot’s first of three Cartesian axes. One of the nice features of the Mosaic kit is that several of the more complex subassemblies are supplied pre-built, greatly simplifying construction. This stage of the build consists essentially of…
The Sieg Mini-Mill: One Manufacturer, Many Brands
A full-size turret mill is, of necessity, a heavy, expensive piece of equipment, impractical for most individual owners due to space and/or monetary constraints. For hobby work, however, a so-called “mini mill” can perform very well. The chief limitation of a mini-mill is not so much the quality of the work it can produce, but the size of the work it can handle.
Zero to Maker: The Tools They Are A-Changin’
Making is as much about exploring as it is about building. Exploring new ways of problem-solving, understanding how things are made, how machine components fit together. And this week, for me, about exploring new tools.
Milling Machine Basics
Chicago’s American Machine Tools Corporation buys, sells, ships, and repairs heavy machine tools all over the world. They also maintain a curriculum of free, online, non-brand-specific operator education materials, including the best general How to Use a Milling Machine page I’ve seen. There are no videos, but personally I prefer old-fashioned text and diagrams for this purpose. If you are interested in movies, however, check out MIT’s Introduction to the Mill.
Prototype Quick-Build, Low-Cost 3D Printer
Printrbot, just successfully crowd-funded by Lincoln, California resident Brook Drumm, bills itself as an all-in-one 3D printer kit that “can be assembled and printing in a couple of hours.” Hack a Day’s Brian Benchoff gives a cogent technical analysis. Apart from the Kickstarter itself, Mr. Drumm maintains a Flickr set, a Vimeo account, and a fledgling blog dedicated to the project.
