Anyone who uses a CNC machine eventually realizes the importance of the Zero point. This usually happens when something goes wrong during a machining cycle, the machine needs to be reset and the current zero is lost. Fruitlessly searching for a lost zero prompted me to develop a repeatable process for finding the same zero time after time. Here’s how I do it.
The Haberdasher’s puzzle is a simple 4 piece puzzle whose parts can be assembled into a square or an equilateral triangle. Solving the puzzle is easy, but for me the beauty is in the geometric dissection used to make the parts.
A long time ago I made one of these using a ruler and compass. Now I have a CNC, I was interested to see how well a CAD drawn and machine cut set could fit together.
My electronics based projects most often end up in a box of some sort. with related knobs, LEDs or displays showing on a front panel. Over the years I have tried a number of different ways to make these panels look nice, and I think I have finally found a method that looks professional and I am happy with.
