[amsat-bb] Home brewing El. Az. rotators

[Tony VK5ZAI <hutch@xxxxxxxxxxxxxxxx>]

Hi Guys,
Seems a lot of talk about rotators lately, have you thought about 
building up your own, I did this around 15 years ago and the system has 
never been switched off apart from twice when moving QTH and the 
occasional service, greasing etc. My present QTH is 300 yds from the 
Southern Ocean and we get some almighty winds in the winter but it keeps 
on going. It's driven by 2 windshield wiper motors and constructed of 
parts that can generally be scrounged from vehicle and machinery junk 
yards etc. You will require a small welder to put it together and access 
to a lathe but really there's no great precision required in it's 
construction. I've described it's construction on my web site listed 
below. hopefully it will be of interest to some of you.
