Next Project: Tapping Arm

May 10, 2010   //   by Bob Warfield   //   Blog, CNC Projects  //  No Comments

Having finished my home switch project for the CNC mill, I started thinking about what my next project ought to be. I wanted something simple but very useful that would combine a little CNC with a little welding and fabrication. A tapping arm is perfect for that task as I was reminded when reading a…

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

Optical Home/Limit Switches for the IH Mill

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

I finished installing and testing the optical home/limit switches on my IH Mill:

X-axis home/limit switch…
More detail is available on the project page. These little beauties will save me considerable time!…

Diamond Knife Sharpener

May 2, 2010   //   by Bob Warfield   //   Blog, CNC Projects  //  4 Comments

While we’re on the subject of nice shopmade tools, check out the cool diamond knife sharpener:

Put a high quality commercial diamond wheel to work and your pocket knife will be razor sharp in no time!
You gotta love massively over-engineered and finely crafted shopmade tooling!…

Bodysnatcher’s 5C Collet Indexer

May 1, 2010   //   by Bob Warfield   //   Blog, CNC Projects  //  No Comments

Bodysnatcher is a professional machinist I’ve been following over on CNCZone. He has a lathe similar to mine, and has made all sorts of interesting tooling for it. These photos are of a 5C collet indexer he made (comments are his):

A Chuck Hauler

Apr 24, 2010   //   by Bob Warfield   //   Blog, CNC Projects  //  No Comments

One of my readers (thanks, Pablo), sent me a link to this great idea over on the Candlepower forums. Lots of interesting stuff over on Candlepower, BTW. Folks over there are making custom high-tech flashlights, and a lot of the work is really cool.
This idea is designed to make it easier to mount medium-sized…

Another Use for a Dual Indicator Rig (aka Traminator)

Apr 22, 2010   //   by Bob Warfield   //   Blog, CNC Projects, Techniques  //  No Comments

I love my “Traminator” (what I call the dual indicator tramming tool I received as a gift), but had thought of it as a very special purpose tool only useful for tramming the mill until I saw this picture on a Practical Machinist thread:

Ray Behner created this tool, and what a cool idea it…

Kurt Vises for Sheet Metal Bending (aka Way Covers)

Apr 13, 2010   //   by Bob Warfield   //   Blog, CNC Projects, Techniques  //  No Comments

Kurt-style vises have 1001 uses, I am sure. Maybe this is 1002. Having my nice set of Vise Jaws of Doom sitting on the table from an engraving project gave me an idea. Could they be used as a sheet metal brake? You betcha!
Here are the jaws:

Here they are being used to bend…

4th Axis Disk Brake

Apr 12, 2010   //   by Bob Warfield   //   Blog, CNC Projects  //  1 Comment

Nice video of a disk brake to lock a 4th axis for machining:

The caliper works by screw action. The cylinder rotates a screw that snugs the brake pad on the rotor. This is a very high performance shopmade 4th axis. The servo will spin it fast enough he can use it as a lathe.…
