Project Tag: Laser

I use a laser cutter, a preordered Glowforge Pro, for detail work on many projects. Here are some of the latest.

  • Faux Neon ”Little Havana“ Marquee Sign and Dance Structure

    Faux Neon ”Little Havana“ Marquee Sign and Dance Structure

    This two-in-one sign pairs LED-powered fake neon script with big galvanized-metal-wrapped marquee letters. Each half is built on a common base plate, making the sign strong and easy to hang and handle.

    The completed sign is 5½ feet in length, 18 inches high, and weighs less than twenty pounds.

    Design Process

    Below are my initial sketch, a high-fidelity mock-up, and a representation of the finished design I used as a cutting pattern.

    This initial sketch was done to give an early approximation of what I had in mind to get feedback as early as possible.

    In the color mock-up, you can see I broke the HAVANA letters out of the base shape to give the sign a more interesting silhouette.

    The client wanted to see a different typeface for the word “Little,” so in the final pattern for the sign you can see that change as well.

    Plans also called for a structure to hang the sign over the entrance to a dance floor, and some columns from which to hang lights around the perimeter.

    Layout and Fabrication

    I planned to lasercut the Little as well as the HAVANA letters, but the main back panel was too large to reasonably produce with my lasercutter. Instead I made cardboard mockups of the parts I could cut and used them to lay out the rest of the sign.

    At the upper left you can see the off-the-shelf blinky lights I used for the marquee letters. I checked the width of the bulbs against the holes in my cardboard mock-up H to ensure they’d fit snugly in the final parts.

    This process revealed that marquee letters were too close together in the initial drawing. Especially when boxed with metal strap, I worried they would run together and become difficult to read.

    The fix was easy: I elongated the oval base shape and made room to space the letters out a bit more.

    The faux neon part is built like a lightbox. I used a foam cutter to make the spacer that separates the Little face plate from the back. I cut a green acrylic lens with a frosted clear face, and mounted eight rows of double-density LED tape inside.

    The columns are simple two-piece plywood boxes with identical notches at the top (for hanging string lights) and the bottom (for the feet).

    Not shown are internal sleeves that connect the top and bottom of each column.

    Also not shown are sand-filled weights I made that fit inside the bases, but leave enough room for electrical wires to pass inside the columns instead of taped to the sides.

    The base of each column is supported by crossed legs. I made these in two versions, an “over” and “under.” Here you can see an example of each. I cut the slopes with a bandsaw. Beneath them are the blanks I made for each version with a table saw sled.

  • 400 Bottles of Beer Wall

    400 Bottles of Beer Wall

    My client wanted a rack to hold a wall of beer. A corporate logo would be painted on huge grid of bottles, which would then be dramatically and variably backlit. The rack therefore needed to have a very narrow profile and a largely open back.

    Horse and Shoe Engravings

    The client provided an image for this project, but it’s wasn’t quite suitable as-is. To change it into something that would look pleasing engraved, I set up a few adjustment layers in photoshop in the following way:

  • Let’s Explore 2½D Plywood Engraving

    Let’s Explore 2½D Plywood Engraving

    I drew this image a year or so ago while daydreaming about a spaceship made of a junkyard tilt-a-whirl bucket, take-off appliance doors, trash cans, old road signs, and various urban debris. But as readers who have seen The Explorers will recall, the heart of the ship was was more technological—an inertial damping field created with an alien-inspired but homemade circuit, an Apple ][, and a swiped car battery.

    The style of the drawing was intended to ape a woodcut. In this project I’ve set out to translate it to an engraving as a means of learning the ins-and-outs of the new tool in my kit: a laser cutter and engraver.

  • No Soliciting Signs

    No Soliciting Signs

    Made from painted birch plywood with an 1/8″ face and 1/4″ backing panel. The NO THANKS letters are laser cut and the phrase below is laser engraved. I stained the surface of the backing panel that’s visible inside the NO THANKS letters to match the dark brown color of the lasered plywood edge. Painted border in three sating colors, a burgundy, periwinkle , and sage.

    Overall dimensions are 2 3/8″ high by 10 1/4″ wide. Finished thickness is 3/8″.
