Need help finishing up a parabolic solar hot water heater

Topic Type: 

i hope this is the correct forum for this post. If not, please feel free to move it.

Well, this is where we are at. We are a small team trying to finish up a parabolic solar hot water heater.

It has been adapted from different ideas from the internet and as such, we have run into a couple of design snags.

Here are a couple of photos of what the problem is. We need to "replace" this long bolt with something "better" The aluminum rod needs to be about 6" from the top bar in order to be parallel to the structure that it is attached to as well as the parabolic collector.

This is a link to the "previous" iteration of our solution...


Here is the photo for the current "solution"...


Here is the photo where the rod is connected to the motor assembly...


If you need more info or more pics, please indicate.

In the meantime, have a great evening!
