Everything came together for the first real use of the forth axis mandrel for ring carving. It’s nice when the plan comes together and everything works as intended. There was of course far more than just making the mandrel. There is the CAD design stage and the CAM (Desk Proto) for generating the G-code for the 4th axis. Then running the G-code on the micro-mill. I use LinuxCNC and I had to write my own metric post processor for Desk Proto. Not all that hard, actually. I made a USC (inch) version too. One tiny code change.
The first picture… Continue reading
I was self taught in brazing and soldering metals long before I became certified By Harris Industries (Now called the Harris Products Group) about 35 years ago. Nothing has changed about the processes in all that time. It is a skill that can easily be developed and improves with use or practice. Most skilled hobbyist can quickly master the basic technique.
What is required is an understanding of the science and what is going on in the heating process. I have always needed to know the why of any process before I could truly master the how. Silver brazing… Continue reading
