The catapult range had some very large panels that fold over into the closed position. The puny hinges on these panels broken pretty quickly and I was in need of something more substantial which was why I invented the piano hinge. I made a really long length of hinge and ran it all the way down the sides of the range, it was a very effective solution.
8 years ago I was making my first CNC cutter on the dining room table and I was just thinking to myself how much times have changed since then. OK, well maybe not that much I'm still making a CNC cutter on the dinning room table (the same table, different room) but I do have a little helper nowadays.

I designed this piano hinge a long time ago but I was holding it back for a special occassion. Since then I've been distracted and the occasion never came so I'm releasing it today. The hinge is made from 2 sheets of material a groove is engraved along the middle and a piece of piano wire inserted along the groove. It's a strong sturdy hinge that can be created to any length you require, the only minor issue is that it leaves the burnt side out, but that can be cleaned. (svg here)

I'm working on another project for the UK maker faire but it's tricky given that my laser cutter is still down. While I was at the unit this morning I quickly drew this frame work up and cut it on one of our demo machines. The idea is that you can take a snapshot of a drawing and quickly digitise it for laser cutting. The base plate has a notch to make it easy to put the drawings in the right place, the vertical has a slide adjustment for height, the webcam itself has a ball joint for easy angling and the whole vertical arm slots into the base to make it easy for travel.
