materials for building windvane
hi all,
Ive been browsing the US patent database and looking at pictures, thinking about building a windvane for a thunderbird 26. partly because of the cost, and partly just for something to do. building it shouldnt be too hard for me, i have plenty of time, access to materials and a cheap supply of expertise and labour who are willing to work for beer. what im wondering is about materials.... is stainless the only way to go, or is brass a better option for some parts (gears?) . Are the gears on the commercial units made of stainlesss? for bearings, are the plastic type that are sealed or lubricated by water appropriate? are the shaft sections generally a standard hollow section, or are they a heavy wall thickness? Thanks, Shaun |
