MSRaynsford

If the Snijlab living hinge design is going to be called the sninge then the MSRaynsford hinge design can be called the Minge, oh no, wait a minute.... The useless boxes used folded card as a hinge and I figured there had to be a better option. By turning the fingers of wood through 90 degrees I can get parts that are rounded in the right plane. Each finger had to be etched on the overlap so that they can wedge into the sheet but still move freely where they overlap. The fingers are then all pinned to allow the hinge to rotate. ( svg here ) 286/303

I've not seen a living hinge with rounded edges yet so I made one ( svg here ) 285/302

A while back I made some cardboard boxes , that project is still in the works but here is the next part of it. A hopper to hold the boxes in a stack 284/301

The Escher Lizard spiral is now available for purchase, this 400 piece item comes ready assembled and attached to a sheet holding all the lizards in place. This item varies slightly with the 3 different colours, red, white or brown lizards being outmost. ( svg here ) 283/301

I've started making parts for the Derby 'What if machine'. I want to run ball bearings along girders for part of my machine so I drew out a test rail today. I was quite surprised by how small the incline needs to be to get the ball rolling. 282/294

I tried to use this motor in a previous project and the mount was really naff and the whole project was a bit of a failure (will post it at a later date). A simple project just to mount the motor securely against a surface. This just needs 3 holes in the surface it is to be fixed against, expect to see this is another project soon too. 281/293

I've been working on a project for Derby Silk Mill   that they are calling the 'What if machine'. It's a Rube Goldberg machine with a twist, instead of assembling all of the machine in the museum over the course of a week, they're inviting teams of people to bring 'modules' for the machine along on the day. Each module is pre built and tested and will have a team of people responsible for resetting the module when it goes wrong. This should allow the entire machine to be reset and run again in super fast time.  So now imagine that you have 20 of these modules and you need a reliable way to connect between the two modules that both teams can practice with before the big day. That's why I created one of these triggers , by placing one at the start and end of the machine you know exactly how to connect to the machine next door. I laser cut 40 of these and assembled them by hand but I wanted to make sure it was all going to work before I...
