leaks and the like are always a problem i can remeber a RADAR cabin that had 2 pipe connectors one for compressed air and one for water someone got it round the wrong way the wave guid was full of water the the cooling system was full of air could not switch on power luckly as flow switches were all wrong all lights and bells.
stil this jobs not going well read on..........
Changes were made to correct the earlier problems and then some retesting could be carried out. As you can see in this picture the tender boiler in now lagged with some heat proof marital in the hope that heat will not be lost through the brass boiler casing.
Once more the water and steam oil was added and the engine left to make some steam pressure once the safety valves were lifting it was time to see what would happen. Off round my track it went and this time looked good I run the engine for a good 20 minutes and all was working well no steam leaks or water leaks and no short circuits.The new red flicker light was working ok so things were looking good so a longer run was under taken to see just how long this engine was going to run for with this larger tender boiler?
Every thing was checked out for this world record attempt. The engine set off at a good speed and was left to run the time was logged and when it stopped due to lack of water the time would be taken once more and this total time was 30 minutes about the same time as the Hornby engines so no improvement on running time.
Then it was noticed that the red light PCB was burning out again and this was due to a steam leak on the main tender heater O ring seal it was clear that this idea was not going to work and that a change should be made to revert to the Hornby copper tube silver soldered in the boiler and the heater fitted in this sleeve.The tender boiler will need to be striped down and the copper tube added then try again.
