Started the week by cleaning and painting the brake rods with silver Hammerite and silvering the oil filler pot off the main servo. The parts and Neatsfoot oil I was waiting on arrived, so I assembled the servo piston, incorrectly, as it turned out, which wasted a day’s work but was quickly corrected and I finished assembly of the servo vacuum cylinder. I’m awaiting a spanner of the correct size so I can dismantle and clean the distributor valve on the top of the servo, so I will make the gaiters next week.

First job of the week was to finish painting the fuel filter bowl and the cab sliding window upright. I then did some detailed final cleaning of the rear brake servo before putting it away to await the arrival of a new leather cup seal. I then turned my attention back to the cab window, gluing the handle on to the sliding pane with silicon and making a proper job of it this time! I also painted red the outside faces of the frame. Another coat of black to treat the thin areas on the fuel filter bowl and that is ready for a filter when it’s dry. Cleaned the brake rod linkage for the rear brake servo next. I’ve now found a supplier for the leather cup seal and am awaiting its manufacture and arrival. Meanwhile, work continued on the cab sliding window, which is now assembled and just needs cleaning before refitting. Final job of the week was to coat the inside of the filter with gear oil, to prevent rust forming, before the filter is fitted.

Activity has been zero of late, due to other pressures, but I did manage to clean the rear brake servo and its oil dashpot at the start of the week. As time allowed, I continued work on the servo, removing the two air intake covers which were choked with oily filth.
