It was an interesting weekend as are all weekends around here. I finished filling in the trench for the new communications lines to the shop. With the cat5 water proof wire coming in I should have this project finished next weekend.
The filled trench that I still need to compact.

With the pressure washer now operating I was able to clean out the inside of the coolant tank. A leak was found by the drain valve so it was loaded on to the truck and will be taken to the weld shop to be repaired.

The wiring has been run for my wife’s office A/C unit.
I made parts for the AR-180B project, trying to get everything off the machines. I have a video to post on that later in the week.
All the AR-180B bolt hold opens are machined. I will bend them this week and then off to heat treat.
And last but not least. Tub after tub of parts were de-burred. I still have more VG1-5 parts to finish de-burring.

There can be a significant difference in voltage between buildings that are grounded separately. This can burn out networking gear if the different potentials are to far out. Generally people use fiber or wireless repeaters for this as dealing with the grounding is hard.
For a lot more discussion on this.
