In this episode we show how we make the Morse Code Plaques The video runs for 8 minutes, with several operations sped up to improve viewing. We still have a few available. You can order one at https://ssl.qrz.com/plaques Sorry but we are unable to accept new orders at this time. 73, -fred
It's a CNC router. It can accept end mills, drills, vee bits, or just about any circular cutting tool with a 1/2 or smaller shank that can safely spin at up to 24000 rpm. The speed control on this one is a three phase inverter variable frequency drive that loses a lot of torque at lower speeds. This spindle motor isn't usable at all below 18,000 RPM and I normally cut everything at full speed, 24000. The motor is 220 volt, three phase, and is rated at 2.2 hp. -fred Here's another video of the same machine.
Found a piece of wood paneling in my shop and made this wooden version today. At least I have a correct version now for my own call
We've come a long way Fred as your "MACHINE" proves it !!! Our ancestors used a wooden mallet and chisel or even before that a sharp stick and a clay tablet !!! Technology is truly COOL !!!
I know you now have the slashed zeros in call signs, but what about a slashed zero in the upper table for consistency ? Is that possible ? I Just prefer slashed zeros whenever possible... guess it comes from being a programmer for many years and always using them to prevent possible code errors...
