WINDVANE self steering mounted

the self steering has been fitted and it just remains for the blocks and line to be fitted

rudder and trimtab in the back of the Hilux

rudder and trimtab on the back of Cagarro

turret, vane and mount

The bearings on the rudder for the trimtab, I made from Delrin

and the bearings on the vane I made from PTFE teflon - there are delrin black "keepers"on the horizontal surface on the aft of the rotating turret and also an Afezelia hardwood lock with inox wingnut on the front - between the rotating turret and the mount is a large UHMWPE washer cut from a 20 litre can so that the turret rotates without binding and wearing the epoxy glass on the mating surfaces - 

below you can see the teflon bearing and the inox shaft

all installed minus control lines and blocks

The above solution is my modification to suit the Setka A of the Wave Rover Mk3 windvane from Alan Mulholland - see below pictures taken of his setup during his visit to Horta

 Battery dangers explained

 The reason I am sticking with lead acid batteries

the reason these things explode and burn is because of cost cutting in their production cheap BMS cheap cells etc etc IMHO.

Maybe having a battery that is at the top of the price range will reduce the chances of this but I am still sticking with lead acid - i could not think of anything worse than this happening out at sea
