JCoPro.net CNC “Art” Giveaway

Posted by on April 7, 2013 5 comments

atst-on-wallIf you saw my first post about making an ATST stencil and thought you might want one, I don’t have the first painting anymore.  Fortunately, I made the stencil out of what I now think is blue polycarbonate, (not carbonite!) so it should last for quite a while.  I had a spare canvas and got bored, so there is now another.

Additionally, I’ve been experimenting with using a modified version of my “Pixel Machining,” AKA halftone process to engrave floor tiles.  I’ve got at least two of these around as well that were experiments.  Finally, I’ve got two wooden “ninja stars” that I’m not doing anything with anymore.  They probably need a good home.

err-tile-engravedIf you would like your own Star Wars Chicken Walker painting, “Err” engraved tile, or CNC ninja star, just sign up to receive JcoPro.net updates via email (right side of the page), Twitter, or Youtube, and leave a comment here to let me know you’re interested.  If you already subscribe, just leave a comment.

I’ll randomly select one person, and ask which “prize” is desired.  From there, I’ll select Read more »

all-hank-drum-notes-laid-outIn a previous post, I introduced the “Hank Drum” and vaguely showed how to make one.  In this post, I’ll go over the dimensions, layout, and the details of how to build and tune this Hank Drum.  As always, I don’t recommend you do anything on this site.

To make this device you’ll need the following:

  • An empty and never used propane tank
  • Calipers (Mine from Amazon), a compass, or some makeshift equivalent
  • Drill and 1/8 inch drill bit (or close)
  • Dremel tool or angle grinder with cutting blades
  • Masking tape
  • Pen
  • Tape measure if you don’t have calipers
  • bungee cord or other strap

Most all of this stuff can, of course, be found on Amazon, Read more »

Hank Drum Construction Overview

Posted by on February 25, 2013 2 comments

The “Hank Drum” as Jackson nicely puts it, is a poor man’s version of the “Hang Drum” or just “Hang” as is the preferred name.  You can find the material for this at your local dealer of propane and propane accessories, and after an afternoon of grinding and measuring, you can have a “Hank” of your own.

Although it’s fun to see it played, what really turned out great was a time-lapse video of us making the drum.  Check out the video after the “read more” Read more »
