Nice write up on a CNC build

Posted on January 23, 2018 by robertwilkie

Author did a good job spelling out the parts and how to build this.  Total cost was around $400 to build.  You could go cheaper with using something besides t-bar. https://www.instructables.com/id/Modular-DIY-CNC-Machine/

Make your own sanding barrels for a dremel

Posted on January 22, 2018 by robertwilkie

Interesting article.  One way is with nail polish, another with high temp silocone, third with two part epoxy(potting compound). but may not work the best with heat based circuits. The author does a good job of testing several different methods.  … Continue reading →
