Solid Carbide End Mill Grades, Geometries, and Coatings

Jul 6, 2012   //   by Bob Warfield   //   Beginner, Blog, FeedsSpeeds, Products, Techniques  //  1 Comment
Carbide Grain Size

Why are some end mills so much more expensive than others, and are they worth the cost?
Every machinist must have wondered about this question at some point.  Many develop fierce loyalties to the brand that has worked for them.  Manufacturer’s recommended speeds and feeds fall into bands depending on the material and type of…

Imagine It + CNC = Built It

Titanium Pen

I got involved with CNC because I like to create things.  It is the ultimate tool for it.  With the right CNC Skills, if you can imagine it, you can probably built it.  I confess I have a serious Design Fetish.  I love great Design.  Objects can be art.  They can delight our senses and…

Better Vise Mounting Clamps for Kurt-style Milling Vises

Jun 22, 2012   //   by Bob Warfield   //   Blog, CNC Projects, Products  //  4 Comments

I’ve been using these for a while, but thought I’d pass along the idea.
I had been using the normal clamps that came with my table clamping kit up until I got my Glacern 6″ Premium Vise. It came with a nice clamping kit that I like a lot better:

Old Style…

New Hotness…


Stallion Trunnions for 4th Axis Work

Jun 17, 2012   //   by Bob Warfield   //   Blog, Products, Techniques  //  1 Comment

I’ve collected some parts like a harmonic drive, but I haven’t started my 4th axis yet. It’ll be some little while before I get around to it, but meanwhile, I love looking at tooling and setups for 4th axis work. Recently I came across the Stallion Trunnions by Martin Manufacturing, which let you mount a…

Parkerizing Guns, Tools, and Parts in a Small Shop

Jun 16, 2012   //   by Bob Warfield   //   Blog, CNC Projects, Products, Techniques  //  No Comments

I’m a sucker for metal finishing and treatments because they add that final finish that leaves whatever you’ve made looking very professional. They can also add durability and rust proofing. Parkerizing is a popular metal treatment for firearms because of its incredible durability and resistance to corrosion.  It uses a chemical called Manganese Phospate that…

Neat Little CNC Toolroom Lathe: Harrison Alpha

Jun 16, 2012   //   by Bob Warfield   //   Blog, Cool, Products  //  No Comments

Despite my CNC gang lathe fetish, a CNC toolroom lathe would be a more useful thing in my own shop. Here is the sweet little 13″ swing Harrison Alpha:…

CNC Plastics Project: Stepper Motor Covers

May 31, 2012   //   by Bob Warfield   //   Blog, CNC Projects, Cool, Products  //  2 Comments
Step Motor Cover from PVC Lumber

I first wrote about these nifty covers back in 2009.  Here is what they looked like from that article:

You can buy them inexpensively from various sources.  I believe CNC4PC has them, for example.
But lately, I’ve come across two different folks who made their own.
Here is Connor’s version from his CNCZone G0704 conversion…

Bar Feed and Lever Collet Closer on a Sherline Lathe

May 5, 2012   //   by Bob Warfield   //   Blog, Cool, Products  //  No Comments

I recently came across this cool video of a bar feeder and lever collet closer on a CNC Sherline lathe:

I couldn’t find much more about the project, but it looks like this fellow is selling these on eBay.  I think this is the first time I’ve seen a bar feeder on a hobby lathe,…

Amazon Wants to Be McMaster-Carr

May 5, 2012   //   by Bob Warfield   //   Blog, Products  //  No Comments

If you’re like me, you probably use McMaster Carr a lot to order small parts.  They have a nifty graphical catalog and they carry almost anything you could imagine.  Well, it looks like Amazon wants to do the same thing with their new Amazon Supply web site:

Tell us what you think of Amazon Supply.  …

Small Injection Molding Machine: Morgan Press

Mar 30, 2012   //   by Bob Warfield   //   Blog, CNC Projects, Cool, Products  //  9 Comments

I got a note from a machinist friend saying that he’d just gotten a used Morgan Press off eBay and had been able to get it working.  I hadn’t heard of one of these machines before, so I went and looked it up.  For the ultimate do-it-yourself or Maker small shop, this would be a…

Harbor Freight HVLP Spray Guns Work Pretty Well

Feb 21, 2012   //   by Bob Warfield   //   Blog, Products  //  No Comments

I’m in the middle of painting panels for the flood enclosure I’m building for my mill and wanted to pass along a mini-review of the Harbor Freight HVLP spray guns I’ve tried.  I started with them more expensive one they sell, #93305:

Not such good luck with #93305…
To be honest, I didn’t have very…

Fixturing with Vacuum Tables, Vacuum Chucks, and Vacuum Clamping Systems

Feb 18, 2012   //   by Bob Warfield   //   Blog, CNC Projects, Products, Techniques  //  12 Comments

I’ve been interested off and on in vacuum fixturing for quite a while.  My brother is in the design stage of a big CNC router table, and wants to build in a vacuum table capability.  I had been dimly aware that it is also applicable to CNC milling operations on metal, but hadn’t really delved…

Timesaving Tip: Drill and Chamfer/Deburr in the Same Operation

Jan 5, 2012   //   by Bob Warfield   //   Blog, Products  //  1 Comment

I heard about this gadget on CNCZone and thought it was pretty cool:

You clamp the chamfer onto the twist drill at the right height and then just program the depth to get the desired chamfer or deburring. You can also get full-on tools that have a chamfer built right into the tool geometry, but…

Motion Control Boards Take Mach3 From Hobby Class to Industrial Grade, Part 2

Dec 24, 2011   //   by Bob Warfield   //   Blog, Products, Software, Techniques  //  32 Comments

Our first article in this series discussed how using Windows to solve all of the CNC Controller problem suffers because Windows is not a real time operating system. Simply put, if the task of sending motion control signals (step + direction pulses) to the motor driver hardware is interrupted, we have problems. Those signals get…

Equipois ZeroG Technology Makes Tools Weightless

Dec 17, 2011   //   by Bob Warfield   //   Blog, Products  //  No Comments

I came across this video by accident, but thought it was worth sharing:

ZeroG technology makes tools weightless…
These guys have a technology based on the steadycam technology for cameras that supports heavy power tools so they’re weightless. Workers using the tools can work longer or harder without getting fatigued.
Wouldn’t it be cool to…
