Building a Wooden Bench Plane

images: 

The best tool I own is probably my Lie-Nielson block plane. I've been taking some time lately to hone my sharpening skills and encountered the idea of building my own hand planes. It's a very attractive idea since good handplanes are anywhere from very to extremely expensive, and being able to make my own would allow me to build any variation of specialty plane I might want to try. Plus, my CNC router makes forming the basic shapes as easy as digitizing my idea into CAM software.

CNC Part 15: Aztec Calendar

images: 

The g-code for a detailed aztec calendar is a well-known benchmark around cnczone.com. To cut this pattern, the machine has to make thousands of movements staying within a few hundredths accurate. I tried cutting one for my parents' xmas present from some nice brazilian cherry. I joined two planks to get the required 16" width, flattened the top and sprayed a light coat of polyurethane to help avoid chipping during the lighter detail passes. Next time I would apply a thick layer of poly since a few detailed places show some chipping.

These were taken about an hour in.

There is a great cable tray design shared online by Kronos Robotics at http://www.kronosrobotics.com/krmx01/krmx01upgrades/dragoncable/

This made for a perfect "first cuts" project with my router. One learns a lot of things quickly in the first few hours operating a router like this. Work has to be held down very firmly to produce the shape accurately. And a cable tray like the Dragon is very necessary to keep cables safely away from the bit and from being stretched across parts of the machine.

CNC Part 12

Motors installed and wired to controller / controller connected to PC. I jogged each axis end to and repeatedly to shift things into place, tightening a little each trip. Things are looking pretty well square after building a sharpie holder and jogging in large rectangles. Here is an old javascript/easelJS drawing pattern I made, now adapted to output g-code. Router mount on the way. For now, I have an overly powerful plotter / sharpie ruiner.
