Work Day 7th July 2018

LCP
Three tasks carried out in the LCP this week. The replacement of firmware on the SCSI controller with a later version which we been able to obtain, refitting the Argus 700 monitor on the front of the computer rack and adjusting the Vertical Sync on the Jamming Assessment monitor which involved removing the monitor from the display console so that the vertical sync pots could be accessed. Here is the monitor, now with a stable picture again after adjustment.

The monitor panel was not part of the operational LCP and has been fitted for future software work.

The plan is to repaint the internal walls and roof of the LCP, the original colour being Cockpit Green. After fifty plus years plus the internal paint is engrained with dirt and faded as illustrated in this photo showing a test section of the internal wall.

Note the contrast in colour but the fresh paint is still wet. The accesses covers for the fluorescent (now LED) lights in the LCP roof have been repainted and can be seen in the photo of the covers being repainted.

The Simulator was run up and remains serviceable, this was also a good test for the new SCSI firmware.

T86
Dave carried on doing a first rate job on prepping the wheel arches. Unlike the cabin structure the wheel arches and the rest of the chassis is steel and not alloy so corrosion is a significant issue besides the flaking paint and dirt. See below for the results of Dave’s work on one of the wheel arches. Dave also treated the corrosion with an inhibiter, most being applied to corrosion but also to his overalls!

A lot of work on refurbishing ‘parts’ from the T86 is taking place away from “2nd Line” (so 3rd Line = Home!). These include chiller and air condition covers. Once the corrosion, loose paint etc. are removed, they are returned for painting.

Two further images are included to illustrate the sort of problems being treated. Corrosion between a steel latch and alloy cover and perished metal RF/Insect shield. In the case of the latch it will be removed from the cover, both being treated and repainted before re assembly. The original metal shields will be replaced with plastic insect shields as the T86 will not be transmitting again!
