One particular question that’s typically asked is what the plastic under the Chrome and 24kt Gold Plated BrickArms accessories looks like. Here I’ve unveiled the mystery by peeling pack some of the gold plating from a bit of sprue to expose the plastic underneath.

The color itself is not all that exciting, but what is neat about that plastic: it has a nickel component mixed into the ABS. it is this additive that allows the gold or chrome to be electroplated onto the plastic.

The Truck – Lightly Loaded

I created this longtail delivery bike custom for OnTheMove Organics. Virtually 11 feet extended with an eight foot wheelbase, it will carry 12 common plastic tubs for a gross car weight of 500 lbs. The rear wheel has zero dish and uses a special 14mm BMX axle with a 6-speed cluster. The kickstand can be remotely operated by cable with a special pull manage mounted atop the stem. Chain slap is minimized with a layer of UHMW beside the chainstay. Mostly made with materials and bike components rescued from the landfill.

The anatomy of a tunnel boring machine – a look inside the machine that will dig the SR 99 tunnel in Seattle

How does a tunnel boring machine work? The answer, as you might expect, is complicated. The custom-built machine that will dig the SR 99 tunnel is designed specifically for the ground conditions beneath Seattle. This graphic illustrates a few of its more notable parts.
Check out this short video (or view on Youtube ) to see a similar machine in action. Tunneling will start in 2013. Learn more about Bertha, the SR 99 tunneling machine, at her webpage or follow her on Twitter @BerthaDigsSR99.
