Special Purpose Robots

Dec 3, 2010   //   by Bob Warfield   //   Blog, CNC Projects, Cool, Techniques  //  No Comments

We’ve reached a point where its actually pretty easy to build special purpose robots for various manufacturing tasks. For example, here is a robot that cuts off blocks of resistors from the rolls that feed pick and place machines. It’s used to put together parts packages for electronics kits (hat tip to MAKE Magazine for…

Having a little trouble loading that 4th axis onto your machine table? No worries with this Raytheon powered exoskeleton:
Isn’t technology cool?…

Rob Wilson’s “Big Dog” Bicycle Built for Four

Sep 28, 2010   //   by Bob Warfield   //   Blog, Cool  //  No Comments

I love it when somebody does something offbeat, but lavishes tremendous care and craftsmanship into the design. I’ve got a few like that from MAKE magazine’s blog (if you haven’t subscribed, you need to!). First up is Rob Wilson’s “Big Dog” four person bicycle:

Doesn’t Big Dog look like it would be a blast to…

Larsplatoon’s Electromagnetic Coil Gun

Sep 28, 2010   //   by Bob Warfield   //   Blog, CNC Projects, Cool  //  1 Comment

A coil gun propels projectiles using an electromagnet. They’re sometimes incorrectly called rail guns or mass drivers. The military has experimented with rail guns (an alternate style electromagnetic weapon) on a large scale (large meaning battleship gun-sized weapons at the Naval Surface Warfare Center with a 200 mile range), but Larsplatoon has build one for…

Rock Lobster? More Like Robot Lobsters

Sep 24, 2010   //   by Bob Warfield   //   Blog, Cool  //  No Comments

This video (hat tip to MAKE Magazine) was a real hoot:
Is there anything some talented person somewhere hasn’t made or isn’t working on as we speak?…

Homebrew 250W CNC Laser

Sep 24, 2010   //   by   //   Blog, CNC Projects, Cool  //  No Comments

This is one bodacious project that I first heard about on the MAKE Magazine Blog. It’s creator has a site that tells the story of how he spent a total of $15K and 2 years to build it, but the results speak for themselves:

There’s the laser cutter in all of its glory…

A “Lazer…

Have You Seen the Maker Movement, MakerBots, and RepRap?

Sep 24, 2010   //   by Bob Warfield   //   3D Printing, Blog, CNC Projects, Cool  //  No Comments

I’ve know about the Maker people for a long time, but only recently subscribed to the MAKE Magazine blog, and it’s been a lot of fun. There’s a lot of homebrew CNC, but a lot of other projects too. Sort of a “nerds gone wild” sort of motif. Many of the projects are fascinating, but…

Drawbots

Sep 19, 2010   //   by Bob Warfield   //   Blog, Cool  //  No Comments

I love the idea of Drawbots!
What’s a Drawbot? It’s a little CNC machine used for drawing or painting. They’re typically 2D devices that are suspended on cables. If you’ve been to an amphitheater event any time recently that had a lot of video, you may have seen a video camera suspended on something similar.…

Ferrari V4 Motorcycle

Sep 18, 2010   //   by Bob Warfield   //   Blog, Cool  //  No Comments

Crazy cool is all I can say:

Nothing like a good rendering to stimulate the appetite, but it leaves you feeling hungry, doesn’t it? How long before some intrepid CNC’er decides they can’t wait to have one, I wonder?…

Shopmade Jet Engines

May 7, 2010   //   by Bob Warfield   //   Blog, CNC Projects, Cool  //  No Comments

Someday I want to try my hand at making a little gas turbine (jet engine). In many ways, these are some of the most demanding machining applications you will find. They are similar to machine spindles (another demanding application) in the sense that they are rotating and require precise and durable bearings, but they are…

Machinist’s Hammers

May 2, 2010   //   by Bob Warfield   //   Blog, CNC Projects, Cool, Products  //  1 Comment

A pretty common beginner’s project in the machine shop is a brass hammer. But here is what happens when a more experienced hand makes a hammer:

Long nylon face is for installing pistons…

That is one sweet hammer!
Postscript
Here is a review of “The Hammer” with some information on how to get one.…

Dave DeCaussin is Still At It

Apr 4, 2010   //   by Bob Warfield   //   Blog, Cool  //  No Comments

Dave is the “D” in “Fadal”, so he knows a thing or two about CNC. Lately he has been building tool changers and enclosures for Asian mills:

Don’t they look great? Nice powder coated sheet metal will do wonders for the aesthetics and is very functional.

A little more about the tool changer…
