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.
