From a January, 2010 piece on DesignBoom: Hook and loop fasteners have become commonplace features of both industry and households. However, they have one snag: they are too weak for many applications. Hook and loop fasteners made of spring steel have now been developed at the Institute of Metal Forming and Casting of the Technische […]

Her self-made challenge, now 9 months underway, is a venture called Makeshift. Starting September 1, 2009, Purschwitz — an award-winning clothing designer and the founder of Vancouver-based Hunt & Gather […]

This tutorial by Instructables user nepheron shows you how to embed ordered optical fibers in cast cement to produce a small lump of concrete that will transmit light. It’s based on Litracon, a commercial architectural material that, I believe, invented the concept. I’ve been considering a very similar “cast your own translucent cinder-block” type tutorial for the Make: Projects series for some time.

“Micarta” (Wikipedia) is a genericized trademark that refers to a rigid composite material made from laminated paper, fiberglass, cloth, or other material impregnated with a plastic resin. It is commonly used as an electrical insulator and as a tool handle, particularly for knives.
Cliff Fendley of Fendley Knives, together with fellow knifemaker Mike Carter of Carter Crafts, set out to make some “micarta” of their own using scrap denim and epoxy resin. Even better, they documented their efforts with a detailed series of photos so others can play along at home. Kudos to both makers for “open-sourcing” a method they could easily have kept under their hats as a trade secret. [Thanks, Alan Dove!]

If you’re interested in materials science, design, architecture, and/or chemistry, and you live in Austin or the central Texas area, you should not miss the UT Austin School of Architecture Materials Lab, located in room 3.102 of the West Mall Office Building on The University of Texas Campus. They’re closed this week for Spring Break, but are normally open from 9-5 every weekday. It’s open to the public, and is chock-a-block with physical samples of all kinds of exotic materials that would otherwise be difficult to get your hands on in small quantities. Anyone can poke around, and registered students can check out samples just like a book-library.
If you’re not in the area, the UTSOA Materials Lab is building an online database of its collection organized by composition, form, properties, process, and application. And although they don’t have photos of all the samples uploaded yet, it’s still fascinating browsing.

I make a bunch of stuff out of plywood. A lot of it is utilitarian furniture–bookshelves, workbenches, occasional chairs and stools. I’ve been wishing for a long time that I could find a plastic substitute material, like the synthetic decking and lumber I see for sale in the hardware stores these days, to use instead, not only for the eco-friendly aspect, but because I’d like to have a material that was naturally water-resistant and did not require finishing.
That’s why I was excited to learn, a few months ago, about EcoSheet, which is a “plywood replacement” panel material manufactured by British firm Environmental Recycling Technologies. I hit them up for a sample and they sent me a 4″ x 4″ x 3/4″ piece of the stuff, which is pictured above. It does not weigh as much as plywood, but seems just as rigid, and drills and cuts easily. And although their initial market seems to be the construction industry, specifically temporary structures erected as barriers and pouring forms, I’m looking forward to experimenting with “off-label” uses when and if it becomes available in small quantities in the US.
EcoSheet is manufactured from 75% recycled material, mostly waste electrical and electronic equipment, and can itself be recycled at the end of its useful life.

My prejudice against keeping things neat is simple: I want to skip the cleaning up and move straight to the next fun thing. I think that many […]
