Waterproofing your Ametek Generator
First section covers Easter Egg method.
Second section below break line covers bicycle tube method
Again this is just a way that I have done it, it does not mean it is the only way.
In this section I will cover the simple "cheap" way I
have found to waterproof your Ametek generator.
Easter Egg Method
To do this, you need 1 of those goofy plastic Easter Eggs, any
color you want, it does not make a difference.
Here we go.
Your egg needs to be taken apart. You have the longer front
section, and the fatter back section.
If you have a shaft that goes out the back that is longer than
the fat end of the egg, melt out the center of the fat end with your
screw driver or wire. I heat them up over the stove and then
slowly melt the hole.
Try to make the hole so the egg will just barely go over the back
Now that your egg slides over the back shaft nice and snug you
need to put a small hole back from the edge about 1/4 inch
back. Just a little hole like 1/8" or so.
Lets put this piece on.
Let it set up while we make the front cover.
Now you should have left over, the long side of the egg.
Carefully melt a hole in this piece to fit over the front shaft. Remember snug if fine it will wear in.
Now make a little 1/8" hole back from the edge of the egg about 1/4" NOT on the end you just made the hole.
Now lets put this piece on the same way with a nice bead of
Let it sit for a couple of hours till the silicone is set up.
Now get your fingers nice and gooped up with silicone and coat the
entire egg piece both front and back EXCEPT the little hole.
This will protect the egg from the elements and make a solid cover.
When you get ready to mount your generator to the Yaw mount you then put a thin coat over the front and back seem of the ends of the generator and any unused holes you may have.
What you just made is a front and back waterproof cap for your
generator. Any water that manages to get past the rotor hub
along the shaft and into the egg area will run down and out the hole
in the bottom of the egg.
In this case gravity is our friend since it will not allow the water to run up hill and into our bearings.
I told you it was Hi Tec. ;)
Bicycle Tube Method
Grab any old bicycle tube and cut a piece off 4 inches long.
Repeat for the other end.
