Brian Kerr's router lathe
Brian Kerr writes: Hi Matthias, I thought you might be interested in seeing another application resulting from your gear generator. I’ve been thinking about a marble machine for a while and as part of it I wanted to have one way of lifting the marbles be done with an Archimedean screw. At first I considered a separate machine using the same small router I have for the 3D pantograph from your design. Here’s the finished jig – or at least the first prototype: Headstock attachment point. It attaches to the tailstock end using threaded holes intended for an extension bed. The “carriage” for the router rides on metal electrical conduit pipes – straight and inexpensive. The crank was a starting point and at first I thought I was going to need some gearing or to use a variable speed drill for turning the rod but once I tried it the hand crank was just the right speed for cutting, although a bit tedious for running the carriage back from one end to the other. Here is a photo of the first cutting.

Understand 1,700 Mechanical Linkages with these Helpful Animations
Mr. Đức thắng Nguyễn (Duc Thang Nguyen) is an engineer from Vietnam. Since his retirement in 2002, he has being working on an amazing animated 3D catalog of mechanical contraptions. Using Autodesk Inventor as a tool, he has documented over 1,700 mechanisms. Through a file-sharing website, Nguyen generously provides an overview of all his contraptions nicely organized into mechanical themes. There are so many to pick from, but here are 10 of my personal favorites: Linkage for tracing a parallelogram Persian joint Application of rack pinion mechanism Planetary clutch Door for limited space Keeping direction unchanged during rotation Archimedean drive Friction cone variator Internal Geneva mechanism Converting interrupted rotation to continuous rotation

Remontoire for Woodenclocks
After developing the design of the Woodenclocks Gravity escapement to the point where it was working quite accurately I had started to think if there might be something else I could do with the clock design to improve the the overall efficiency of the clocks. I had always had problems with the gear train working smoothly and consistently, so this seemed a reasonable area to look at more carefully. By the nature of a clock the gear train is going to have to start and stop with each action of the escapement, so when the escapement is engaged, the gear train stops moving and when it releases it will start moving again, this happens with every tick of the clock. The problem here is that each engagement of the escapement involves a certain amount of friction, and two types of friction at that. Remontoire action One the ways to reduce the static friction in the drive train is to introduce a remontoire , the simplest type of remontoire invented by Robert Robin in 1772. Conclusion

CNC Router Plans: Download free CNC router plans
CNC router plans are a great starting point for anyone wanting to build a CNC router. They give valuable insight on how these machines work. Many of us are very visual people and it helps to see examples of these machines laid out on paper. Some plans are thorough enough to act as a complete blueprint from start to finish while others only offer bits of information. You may prefer to design and build your own machine. This is why we want to provide you with as many free plans and blueprints as possible. Even if you decide to use plans, we strongly suggest you read through the Builders Guide There you will find in depth information regarding all the components and their function. For now, feel free to check out the plans below. JGROs Design This design is very popular among the DIY CNC router community.

More Scale Fun
I have used the juxtaposition of scale extremes as an interest factor in decorating. Here I display items that are normally very small created way out of proportion. It is items like these that make my desk an interesting place to be. The wrist watch normally small and seldom made out of wood is instead handcrafted in a larger scale to serve as a desk clock. It is created by the Michaud family and available from Canvas to Clay. A ball bearing is a beautifully designed piece of engineering that is seldom displayed as sculpture. Eclectic wrist watches are sometimes made out of wood in actual scale for use on the wrist. Other posts about size and scale that might interest you: ©2011, Ashbee Design, Marji Roy
