As built EDM changes

Over the past 6-8 months I have been building the EDM machine I designed some time ago. There are many changes and redesigns that have taken place to use off the shelf components instead of making every part and it has greatly impacted the appearance of the machine. If you look in my models, you will easily find the original design. Here I will post the changes. As you can see, there is not much resemblance to the original design. However, the concept is the same. Then there was two iterations of the new head design. I was having run-out issues with the motor in line with the spindle. This made it necessary to add bearings and a whole different drive concept.
