Day 81

Morning
I came in and got started working on the new stinger brakes. 9-13 arc all have the same setup with the same brake and electrical controls. That same system needs to get onto 2, 3, 4, and 8. I started by looking at 8 arc because it is the most modern. I found some controls in the Rosemont, but the real work is done in a blue stinger control cabinet down in the shack. There is some relay logic done with Rosemont outputs to control the brakes. It can all be attributed to one relay in the panel. I found a similar deal inside the control cabinets for 2, 3, and 4. They are more primitive, but it will all work. I can adapt the current system to use the single relay from the old systems.

Afternoon
I started work on making a drawing of the new panel layout. I got a little distracted by things like Buck-Boost transformers and circuit breakers, but progress was made. I only needed a few parts to make the entire system work. I want to draw up the layout, then pass it off to Jim. He'll know what size enclosure to get and the best way to build them.
