I originally finished high school and entered university hoping to become an electronics engineer because I wanted to design things, create new technology, circuits, robotics, radio communication equipment, debug and develop software for useful purposes. After a few years in the course, I ran out of money and could not finish.  I withdrew from electronics engineering in third year, frustrated with the course. There were some of the most intelligent and technically creative problem solving minds right next to me in the lecture theatre, but they were all being clubbed to death like baby fur seals being told not to think, just memorize equations! This is not what engineering education should be about! The course taught differential equations, time independent Schrödinger equations and Maxwell’s theories of electromagnetism. All of these things are important, but I wanted to learn how to design and build things, not be stuck in a dark room rote learning slabs of equations that can be just looked up in a text book if required.


After leaving university frustrated, I worked as an electronics tech at a calibration lab for a few years and then and started an adult apprenticeship as a dual trade Industrial electrician / indentured instrumentation tech. Ironically both of my jobs involved working with many Engineers who left university with no understanding of which end of a screw driver to use, and no Idea about the difference between a contactor and an electrical contractor.  The best engineers that I have ever worked with had a trade background, worked their way up over many years from being on the tools into management. These guys were highly respected and had an in depth knowledge of all levels between terminating a cable right up to designing power factor and harmonic correction units. I would encourage everyone to be humble enough to ask someone wise if you don’t know something, learn the basics.


My interests are wide and varied. I enjoy the outdoors, hunting, fishing and hiking, and also machining, designing electronics and programming microcontrollers and PLC / SCADA systems. I still am not sure where I want my career to go, but a wise friend once told me to follow the things that interest you, and as you go, you will find your way. 


I documented my CNC conversion in the hope that I may provide inspiration to others to take on a big project, challenge yourself and see what you can learn. -You will even have some fun along the way. It is a great source of joy designing and making a machine, and then using it for something productive.


Machinery can be dangerous, people have lost fingers, hands and even their lives in using machinery. If you are not confident in what you are doing, STOP, and learn some more. Take a night school class, and tinker in your workshop at home. Safety should be first priority, and never take risks with electricity.


Hopefully you will find enough information to demystify the process of CNC conversion, but I haven’t included all of the details like a cookbook would have, this is intentional.


To contact me, send to      CNC “at” graetech.com    with the “at” replaced by @  symbol.

This may seem crazy but it reduces spam from automatic software scanning pages looking for valid emails. I check this mail address about once a week. Feel free to give me feedback, comments, broken links etc.


I want you to make your own measurements and calculations, learn for yourself and carve your own path in life, don’t just copy what someone else has done, build YOUR machine, not someone else’s, it will bring you heaps of satisfaction. Explore the world, Good luck! Go Australia!
