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.
