[papercreters] Re: Solar Design T-square and clam shaped reflectors

In my case, I will be using cob, which is a mixture of straw, sand and clay. I will use that to make a mold, and I will use the mold as a form for a reflector.
A potential problem with the clam shaped reflectors is that they have to point at the sun (No problem there) and the clam shell has to line up with the sun's path. That part might be hard! It means putting it on an equatorial mount or adjusting it to point the same way as an equatorial mount. Perhaps easy, perhaps not.
