I recently sent a series of questions to Aries about their wind vane
and received the following answers on 4/10/12, which I post below as Question/Answer:
It has taken longer than I expected, but Iím finally ready to buy a wind vane
and from a lot of research
believe the Aries to be the best. I do have some questions that Iím hoping you can answer and would like an updated quote in case there has been any change in pricing for my wheel helm
in original quote --> The cost of an Aries Self-steering Windvane for a Columbia
50, with a wheel helm, is $4995
of the Aries Self-steering has not changed.
A problem that came up in forums
was that the plastic bearings in the pendulum rudder
shaft expanded, binding the rudder
shaft. This wasn't a galvanic problem but something to do with the plastic actually expanding. What type of bearings do you use in the new model? If these are nylon roller bearings, can they be replaced with the same type of metal that they contact to prevent expansion and galvanic corrosion
The bushings are made of delrin and do not expand. The needle bearings are delrin as well and do not bind with shaft.
From the forums, I've learned that there is a problem with the stainless set screws, axles, etc. on the fixed pieces that don't have a plastic bearing to insulate them. Can something be used to galvanically isolate these parts
(Lanocote, TefGel, plastic sleeves, etc.) before being shipped to me?
The turning blocks are delrin and the shafts are stainless steel
. They do not bind either. Yes stainless steel
and Alum. will bind in the salt water
enviorment. Grease will help reduce this issue.
What is the best place (or best places) to add a zinc sacrifice anode to deter corrosion
? Alternately (or if you prefer), any places to avoid?
The Aries Windvane does not require any zinc.
have to be added to the new model? If so, what type of oil does it use and how often does it typically need to be topped off? Does it ever need to be changed out altogether?
The Aries Windvane does not require any oil.
Is there a catalog listing of spare parts that would be wise to have onboard. For example, extra wind vanes, bearings, parts that are more subject to wear and tear?
All parts on the Aries Self-steering Windvane are guaranteed for twenty years (except the plywood
vane, so take a couple of extras in case). (You can make them yourself and save $$). You won't break any part on your Aries Windvane unless somebody hits your Aries Windvane. All a sailor has to do to keep it working is to cover your Aries Windvane when not in use and oil moving parts every three days while under way.
Thoughts or feedback ???
