I usually don’t include bolts and nuts in my CAD assemblies, but this was mostly do to not having CAD files for these things readily available. I decided to fix that and create nut and bolt sets: Metric Button Head: https://www.thingiverse.com/thing:3402872 Metric Socket Head: https://www.thingiverse.com/thing:3402887 Metric Nuts: https://www.thingiverse.com/thing:3402714 Each set contains *.STL, *.F3D and *.STP files and have been optimized for […]

I love RIDGID’s Oscillating Edge/Belt Sander. Overall, it is a wonderful addition to my shop and has served me diligently since 2012. It sits on a mobile flip top cart that is shared by my plainer. Now, it is a beautifully useful tool, but the nut on the top of the spindle, the star shaped one that holds the […]
If you have followed, I tried adding a plastic extruder to my CNC Router. The results were less than desirable. Not horrible all of the time but terribly unreliable. So, I finally decided to build my own 3D printer. Having studied RepRap and many other printers I settled on something that I could build with the tools I had, a […]
I don’t currently own a 1911 but that doesn’t mean I don’t appreciate what can be done to customize them. A friend and fellow aviator came to me looking for a set of grips with aviator wings carved in. I was happy to help. The grip texture proved to be the most difficult part. I tried setting up a grid […]
In 2007 I was approached to produce two life clocks from the movie Escape from New York. In the movie, the main character is given 24hrs to live and a watch to show how much time he had left. From reference photos and constraints of the required electronics I was able to generate some design files. The final piece was […]
I have to be honest upfront that I am not a big video game player and have only played Halo enough to do research on the gun. Seems like a cool game, just too many other hobbies to take up my time. I found the AR interesting as it is similar to the pulse rifle from Aliens in function and […]
