Laser Cut Rope Braiding Machine

Surplus store discovery inspires DIY mechanical marvel

Rope braiding machines are mesmerising to watch as they go through their mysterious machinations. Having spotted such a machine in a Surplus store, David from Mixed Media Engineering reverse-engineered the 1890’s product so that he could nut out exactly how the device works.

The result is a 16-bobbin laser cut wonder, with orbiting spools that guide the individual threads into an intricately woven mesh.

“I have been experimenting with some exotics such as carbon fiber yarns (rocket fusalage) embroidery thread for great braclets, surgical tube core with nylon shieth for pressure tubing, and para-cord nylon.”

There has been such a great response to the project that plans are in the works to turn it into a DIY kit on Kickstarter for others to enjoy. To catch a glimpse of those cogs in action, check out the brief clip of David introducing the rope braider at the source article.

Photochemical Machining Goes Bohemian

Digital fabrication meets ancient jewelry making techniques

Rachel Dropp is the one-woman operation behind Raw Elements Jewelry, a brand that combines modern Photochemical Machining (PCM) with traditional jewelry-making techniques. The results are unique hand-crafted pieces that feature a raw, unique style.

The pieces in the Raw Elements Jewelry line drawn inspirations everywhere from French needle point lace to the phases of the moon.

“While creating new collections I adhere to 3 aesthetic themes: rustic nature, bohemian and sacred geometry.”

The pieces are designed by Dropp, who then hammers, polishes, patinas and does the final soldering to arrive at her finished product. “I love incorporating all of the processes” Dropp says, “because it keeps things interesting and it allows me to have a great mix of products to offer to my customers.”

As someone who enjoys working on the creative side, Rachel initially found it difficult to jump into sales. “I’ve had to step outside my comfort zone” Dropp says “to call boutiques that I feel would be interested in selling my wares and to make appointments”.

Stepping out of her comfort zone has paid off for Dropp, who’s jewelry is now available online on her website and Etsy store as well as in boutiques everywhere from Sonoma County to the San Francisco Bay area

I asked Rachel what was on the horizon for Raw Elements Jewelry. “Coming up in August, I will be attending the Bodega Bay Seafood Art and Wine Festival and then in the beginning of September I will have a booth at Bhakti Fest in Southern California. I also plan to launch a new collection of mini sacred geometry charm necklaces.”

You can purchase Raw Elements Jewelry online at rawelementsjewelry.com or at any of the stores and boutiques listed on her site.

Vector Path Crosshatching

A quicker, cheaper alternative to raster fill engraving

Vector or Raster? It’s a question that has goes back to the earliest days of laser etching. Here is an interesting little exploration from the creative team over at Cuddleburrito that scores another point for the Vector camp.

Instead of using a raster fill for a job that required large graphic elements, they devised a way to create the same effect using vector paths.

This saves a huge amount of time, as the laser only needs to engrave the actual paths of the lines instead of sweeping across the entire area. There was an added bonus that the outcome has a more consistent appearance when applied on timber, because the tendency for grain variation to be emphasized (as when using raster etching) had been eliminated.

10 things to know before laser cutting with Ponoko

Useful information for both new users and laser cutting veterans

Are you a seasoned Ponoko maker? Or perhaps your imagination has been tingling and you are bursting to make your very first Ponoko product.

Either way, here is a top-10 list that we think will come in handy for those new to laser cutting, and it also contains useful information that will help more experienced Ponoko members keep things running smoothly.

Let us know what you would add!

1. How long it will take to make and ship your order.

We make all orders as quickly as we can, and how long that takes depends on the volume of orders we are processing at any one time. Due to the number of variables involved, we’ve written a separate post to help you work out the likely total time your order will take.
Read about our order timeframes.

2. If you are using Inkscape, you MUST use our design templates, or your design will be sized incorrectly.

We strongly recommend that everyone use our templates for laying out their laser cutting designs. If you are using Inkscape *it is 100% necessary*. The way that Inkscape works with measurements is different to other vector-based design software packages, and if you do not use our templates your parts will be made the wrong size. If you’ve already got an Inkscape design ready, we have created a guide to putting it on our templates.
Read how to place existing Inkscape designs onto our templates.

…so that’s the first two, and there are eight further important pointers to wrap your head around when you continue reading the full post.   (more…)

Laser cut Sphere-O-Bot

Teaching kids how to build their own mini making machines

Designed for a workshop series that introduces kids to building their own motor controllers, the Sphere-O-Bot is a simple 2 axis CNC machine that can draw on small spherical surfaces. Suggested target spheres include ping pong balls, eggs and even golf balls are apparently worth a try.

There is a thorough tutorial on Instructables that will take you through the thinking behind the laser cut wooden design, and show just how to put it all together. Files are included for the laser cut structure as well as specs for all the hardware required to get the Sphere-O-Bot up and running.

This fun project was uploaded by Juan, a Maker Corps intern at the Children’s Museum of Houston, who says:

“By building your Sphere-O-Bot using a laser cutter, you can achieve a clean look while also reducing the production time of your parts. This design also features an electronics bay for your wires, micro-controller and motor drivers.”

The basics of laser cutting with Ponoko

Helpful advice on how to get started with the Ponoko Personal Factory

For those who have always wanted to give Ponoko a go but are not sure where to start, this training video shows just how easy it is to produce your own laser cut designs.

In a little over ten minutes, Josh talks through the process of using Ponoko, and highlights a small project that makes a great starting point to help you feel your way with the Ponoko Personal Factory.

The material overview covers felt, cut and engraved bamboo, leather, 3d objects assembled from laser cut acrylic, and laser cut plywood. There is also advice on which materials are the best to get started with – and how to avoid common ‘beginner’ mistakes.

Then it gets to the good stuff – a neat little demo of how to actually make your very first product. The walkthrough explains how to use Inkscape to create a file that can be uploaded to Ponoko for laser cutting.

Starting with the Ponoko P1 template, Josh quickly whips up a collection of forms that use both laser cutting (for outlines) and laser etching (for surface details).

The upload process is then explained, with useful tips on how to check your files are correct and also how to order multiple copies of your design. Next comes material selection, which reveals some very useful information – how much it will cost! You’ll see that it’s really easy to switch to another material and see the price adjust accordingly in an instant.

The video wraps up with a few more handy design tips to be sure you start off on the right track.

Sound like fun? We think so. Watch the video, then dive right in!
