Luc I have two Labradors that watch me very anxiously, and rhetorically say....."what's an old man like you doing on the roof!".
I repaired my 5400 by soldering the brass grommets that terminated the pot....When you open the case put the rotor in a tub of some sort....My bearing retainers were so old they were worn, but when I put in new lithium (as I remember) grease the grease held them in the retainer, and used them for years after...Of course we have no ice in San Diego, if we ever do I would move back to Minnesota!!
Hang a dark sensor on one end of the boom....I have a 4 foot skylight cut in my hamshack roof so I can observe the rotors. And when I see ducks and geese going south I know you are beginning to get chilly up there!!
Much easier to devise these things than do them, but you know doing is most of the fun!!
Collateral damages
1-Probably a mess inside? rust? corrosion? mildew? and so on... 2-Upper hole plugged with a metal screw plus silicone 3-Struck something when drilling pass through the casing!!! (Not too lucky with lotto ticket...) 4-Meter does not move anymore probably a wire cut or the pot has been stabbed
Lets the weather return to the minus 0C again and just watch the rotor
Conclusion
Rotor will don't freeze in ice anymore (i hope) and i will have to rely on a visual metering system in daylight and on something else overnight.
Thank's to my neighbour dog a Labrador moaning and barking after me at the end of his chain during the whole operation... Just forget my pliers and screw- driver down the tower!!! as i am not too lucky with my drilling probably the same with my pitching...JOKE ;)
As we can pass in an episode of minus zero C temperature at any moment i don't take any chance and i jump on this +C swing i just remember a past winter with another rotor stuck as water fill in due to a crack in the casing not too happy to have a beam always pointing towards nowhere.
