After some considerations I decided to remove the entire insulation for better access to the airframe. This makes it easier to remove remaining wires, tubes and other unnecessary equipment. I am still missing the footrest brackets, panel brackets and panel hinges which I will have to re manufacture.
D-ABUD/N707QJ is undergoing a thorough cleaning and removal of insulation, wiring and unnecessary tubes. Kitchen cleaner is probably the best cleaning product to use for this job. Note the large amounts of nicotine which were not that easy to remove and required some extensive rubbing.
Control coloums removed, Foot rest removed, wirring removed, Panel brackets removed, cockpit floor wire duct removed.
EPR, N1, EGT and N2 are ready! Tested and found ok. Flap indicators on the right are completed too.
Kollsman Altimeter has been a major challenge. I used a broken spare unit to test a stepper motor on it. The axis for the QNH setting needs to be lengthened to turn a potentiometer. The white flag on the altimeter scale for the KIFIS system can be biased out of
OILY QTY gauges of N88ZL now to be used in the panels of D-ABUD. Now running a 5V stepper motor and the original 5V integral lightning. Look how few components are now involved! Once done correctly I doubt you will ever have to reopen the gauge except for the bulb
Finished the EGT indicators. These were U/S units from ebay (one is from N88ZL) and have been converted to Switec stepper motors for cost/accuracy/maintenance/reliability reasons.
I decided against switching the original lightning to LED to keep the original look at night. Bulbs are cheap and easy to replace and have
