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  //  11 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…

Measuring and Controlling Clamping Force in a Vise

Apr 14, 2011   //   by Bob Warfield   //   Blog, Products, Techniques  //  1 Comment

Found a good thread over on CNCZone that’s all about what to do when your vise clamping force is deforming your part. Precision bores can be particularly finicky if clamping force deforms them during the boring process. You want to use the lightest force that will still properly clamp the part.
One of the best…

Tormach Tool Changer Getting Closer

Mar 27, 2011   //   by   //   Blog, Cool, Products  //  2 Comments

There was an update to their blog a few days back, so check there for full details. The beta test has been underway for about 1 month for some lucky Tormach owners. You’ve probably seen the original Tormach ATC video, but this new one shows a lot of other cool features:

You can see from…

Old Machines May Not Die, But They Need Some Creative Fixing Up

Feb 21, 2011   //   by Bob Warfield   //   Blog, Products  //  No Comments

Many a small machine shop business or talented home hobby shop is started with an older CNC machine. I can’t blame a small shop, let alone a home shop, for not wanting to take on the payments associated with a brand new CNC machine. Once the shop that bought the machine new has fully depreciated…

A Caliper Pressure Device

Dec 14, 2010   //   by Bob Warfield   //   Blog, Products  //  4 Comments

Most machinists know that if you need accuracy to a thousandth (0.001″) or better, you can’t use a calipers. At the same time, the digital calipers is such a convenient tool for ID, OD, and length measurements. Machinist’s of yore were fond of their steel rule, but many of the newer generation are fond of…

Candy Red Powder Coating

Dec 10, 2010   //   by Bob Warfield   //   Blog, CNC Projects, Products, Techniques  //  5 Comments

I love the finish on aluminum IronMan from CNCZone is getting here:

Translucent Candy Red Powder Coat, not anodizing!
While it looks like a nice anodizing job, IronMan reports it is Columbia Coatings Translucent Candy Red. I have the impression from the post he chose it because he didn’t want to go to the trouble…

The Swing-Away Tailstock

May 17, 2010   //   by Bob Warfield   //   Blog, Products, Techniques  //  No Comments

A fourth axis can lead to tight quarters inside a mill enclosure. Enter the swing-away tailstock. Nikken tailstocks for fourth axis work have a swing way feature:

The tailstock up and ready for action…

And here it is down and out of the way so the part can be loaded…
Thanks to Boris on the…
