Springs and brushes

We have yet to move off the dock but much has been accomplished. This morning Tim  descended into the sail locker and soon emerged lugging a huge and heavy electric motor that he had extracted from the bow thruster. Coated with flaking paint and rust he then set about dissecting it in the cockpit. The springs  that push the brushes onto  the armature had succumbed to corrosion and lost their boing. Some brushes were firmly jammed in by salt crystals. We had bought ludicrously expensive replacements out from the UK but fitting the springs required cunning and ingenuity. 

Much scratching of heads and helpful hints from passers by at first did not meet with success. But then a foolproof method emerged. First coil the spring tight with the fine nosed pliers then hold it tightly wound in place with some stainless mousing wire with a few twists. Then ease them on to the peg and nip the mousing wire. Finally retrieve the wire debris from the innards of the motor. Some of the brushes had to be drilled out and the salt chipped off with a screwdriver.

Eventually the motor was restored to 8 working, mobile brushes all firmly held in place by 8 perfectly tensioned springs It was time for Tim to lug his project back to the sail locker and re-attach it to the thruster leg before the latter fell to the sea bed potentially leaving a gaping hole in the bottom of the boat and a water fountain. 

It was with some trepidation that we fired it up. But the suspense was rewarded by a brisk bow thrust from port to starboard and then back again with no sparks, no smoke and no drama. 

I think there is something very reassuring about a man in overalls as it exudes competence, professionalism  and confidence. Thanks a million Tim - I never doubted you for a minute!

Meanwhile Sally and Heather have competed the provisioning and cooked up half a dozen “passage” meals for those rough days at sea. All is stowed, catalogued and spread sheeted.


The wind and the rain sprung up in the afternoon so we retreated to the warm embrace of the saloon to watch the comings and goings and comb the web for ice and weather data. The ice now extends well south of Cape Farvell but boats are now beginning to to reach Greenland’s east coast. Arktika has bulldozed her way into Tasilaq and a British boat will soon be leaving for Kangerlussak. We will bide our time as, for us, there’s still too much ice. Tomorrow we will get the sails on and finish our jobs.
