Draft Box with Double-Hinged Lid


This box design used Direct Modeling techniques in Fusion 360 and two drop-in hinge widget components which were then customized for the application. 

Tiny Tansu

Active again after a hiatus, the Tiny Tansu was inspired by a mizuya tansu rendered at 1/5th scale and designed in Fusion 360 CAD for building with laser cutting techniques.
The designs for the doors and the upper-right box component will still get some revision, and the finish is an open question.
Ultimately, the Tiny Tansu is intended to be a desktop secretary.

The Voccell DLS Laser Cutter

The Voccell DLS 50 Laser Cutter
In December 2016, after 14 months of delays I canceled my Glowforge order and ordered a Voccell DLS 50W laser cutter. I received my DLS 5 months later in May 2017. The Voccell DLS 50 was $3500 at the time including the water chiller and shipping. Today Voccell lists the price at $5000.

The Glowforge

Glowforge describes their product as a "3D laser printer," but it is the same class of device as what the rest of the world refers to as a CO2 laser cutter and engraver. The Glowforge originally went on sale as a pseudo-crowdsourced project by soliciting pre-orders in Sept. and Oct. of 2015 with an "expected delivery" by Dec 2015. They received $28M in fully-paid pre-orders during the phase.

Many delays and feature-changes ensued, and the first finished units were not shipped until July 2017. Most of the backlog was fulfilled over the following year, but some international orders still lingered.

The Makita Cordless Track Saw

Makita XPS01 saw on Festool MFT/3 table with Mafell dust bag attached.
Note tape over arbor hole to improve dust control.
I love track saws. A track saw is a safer alternative to a table saw for many woodworking and carpentry uses. A track saw doesn't require the dedicated shop space of a table saw. And given a long enough guide rail, track saws are ideally suited to working with large sheets of plywood, acrylic -- the primary laser cutting materials. Many laserable materials are sold in large sheets that are much more economical than pre-cut "project" pieces. And some materials are only available in 4'x8' sheets. So being able to work with sheet goods will increase your range of available materials.

Festool makes excellent track saws that dominate the market for good reason. I've owned and used a Festool track saw for years, and I'm a huge fan. But Makita has turned my head with their new cordless track saw -- the XPS01.

IMPROVED: Fume Coffin Pre-Filter


I developed and built the Fume Coffin - Laser Cutter Exhaust Vent Filter to assist with filtering the exhaust vented from my 50 Watt CO2 laser cutter.

But it's not easy to service the Pre-Filter.

In the original Fume Coffin design the Pre-Filter lines the interior of the cylindrical HEPA filter. And accessing it requires opening the Fume Coffin and disassembling the HEPA filter assembly.

This project replaces (or supplements) the original Fume Coffin's Pre-Filter with an inline Pre-Filter that's designed to be easily monitored (it's see-through) and easily serviced.

This new Instructable is an optional add-on for the Fume Coffin project.

Fume Coffin Instructable - Laser Cutter Exhaust Filter

So I designed and built this.

It's called the Fume Coffin, and it's a laser cutter exhaust ventilation filter for my 50W CO2 laser cutter.

Design documentation, build instructions and analysis are all here:

Microwave-bent Plywood

I'm interested in bent plywood techniques.

ZenziWerken uses an intriguing technique to craft this bowl. 6mm birch plywood is cut (a CNC router was used here). Then the cut-out was rinsed with water and microwaved at 600W for 1 minute. The bowl is then shaped in a form (another bowl in this case) with lead weights and clamps. The bowl was allowed to dry and harden. Finally, some wood glue was applied at the tops of the spiral arms.

Box Generators

I have built a handful of laser-cut projects based on boxes generated by www.makercase.com. Starting with generic box designs generated to my size specifications by the webapp, I modify and customize the box designs in Illustrator to create matching nesting boxes, lids, additional supports, ornamentation and other variations.
