A little history about NR6C
My first taste of the hobby came as a Boy Scout and the opportunity to earn a merit badge by learning Morse code. Later in the 8th grade my science teacher worked a 40 meter group every morning before school and that was fun to set with him and listen to them talk. The seeds were planted.
Years later the passing of my Novice
exam in 1979 was quickly followed by passing the Technician and General Class
exam. Then was the time to
buy an HF transceiver and my first choice was the Kenwood TS-820S, the SP-820
speaker, the MC-50 mike and an external 820 VFO and a
four element KLM beam. Then a used Heathkit SB-220 followed and I was
off and chasing DX. In the next six
months I moved on to acquire an extra class license and still hold that original
call. The DXCC award followed shortly
thereafter.
I started
my teaching career in the High School, then moved on to the University where I spent the next
37 years as a University Professor, teaching the subjects of Metalworking and
Manufacturing. In the early
years I taught, Welding, Metallurgy, Machining, Foundry, Sheet Metal and General
Metalworking. I also authored
a text book called
Metalworking, an Introduction.
The last twenty years I focused on automated manufacturing including, 3D
Printing or Rapid Prototyping as it is often called, CNC machining, including,
milling, lathes, EDM, laser cutters, routers and robots and the integration of those
machines. I designed and
implemented two
Computer Integrated Machining centers or CIM cells with milling machines, parts
handling and robots. In the
early 1980’s we were using CAD and CAM and later solid modeling software as the
core of the design and manufacturing processes.
Computer controlled machines were running every day and often during the
night to make parts. Some set ups
ran for 30+ hours and that meant they ran all day Friday, Friday night, all day
Saturday, Saturday Night etc. and were finished when we came back Monday morning.
Truly unattended manufacturing or what is often referred to as lights out
manufacturing at the University.
When the
need for this project came along I could not resist exercising my talents.
I first began to produce 3D printed parts in 1990.
I had experience in Computer Numerical Control (CNC) programming and
could produce 3D models but had no way of making them.
As the technology became available I was printing 3D parts every day and
into the night. I had the
wonderful opportunity to travel both nationally and internationally lecturing on
this Technology. Now, toward
the end of the circle I have the opportunity to share products with my fellow
Amateur Radio Operators.
