AR-15 Mini-Lower Tactical Bottle Openers

Feb 25, 2016   //   by Bob Warfield   //   Blog, CNC Projects  //  1 Comment

What is it about making something familiar in a very small scale that makes it so cool?
I don’t know, but these AR-15 mini lowers made by Kent Durree and buddies are just that size-is-everything factor:

These mini-lowers are 80% complete “paper weights”…

Compared to the full-sized article you can see how small they are……

We’d Love to Help Your Small Business to Grow

Feb 24, 2016   //   by Bob Warfield   //   Blog, Business, Guest-Post  //  4 Comments

When is Cutting Aluminum at 1000 SFM Just Like Cutting at 300 SFM?

Feb 19, 2016   //   by Bob Warfield   //   Blog, FeedsSpeeds, GCode, Software, Techniques  //  2 Comments

Strange question, right?  Almost nonsensical.  Surface Speeds are surface speeds, and a difference of 700 SFM has got to result in a difference to the cutter–probably a BIG difference.  Yet, paradoxically, there is reason to believe, backed by science, that 1000 SFM really can be just like 300 SFM in some cases during High Speed…

G75 and Peck Parting Off For Lathes

Feb 17, 2016   //   by Bob Warfield   //   Beginner, Blog, GCode, Techniques  //  7 Comments

For whatever reason, parting off seems to be the operation on lathes that causes the most people trouble.  Perhaps deep boring operations where the bar is really hung out there is a close second.
Parting off is definitely a challenging operation when you look at it mechanically.  You’re going to take a fairly tiny cutter…

Neat CNC Chess Set

Feb 15, 2016   //   by Bob Warfield   //   Blog, CNC Projects  //  2 Comments

I recently saw this chess set by Kelly Fasnacht posted over on the LinkedIn CNC Programming group and thought it wa really neat.  What I like best about it is all the pieces can be made on a lathe.  The Knight is usually a sticking point that has to be done on a mill, but…

Boeing 787 Dreamliner has a huge amount of Composite Construction to save weight…
What are Composites?

I was just over at Santa Cruz Electronics, our local Tormach dealer in Northern California, when I happened to spy a happy little CNC mill in their back room.  Seems they’d just taken delivery on one of the new Tormach 440’s.  I have to say, it is just the cutest little CNC mill ever, and…

CNC, Ghost Guns, and Why the Genie Can’t Be Put Back Into the Bottle

Feb 1, 2016   //   by Bob Warfield   //   3D Printing, Blog, CNC Projects, CNC Router  //  4 Comments

An acquaintance of mine recently got in touch.  Our conversation went something like this:
Acquaintance:  “Bob, you’re involved with CNC, aren’t you?”
Bob:  “Yes, I run a business that offers Software and Information to CNC’ers.  How can I help?”
