Thanks for the compliments everyone. Thing is robert1234, I am quite busy trying to learn how to build a .com with WordPress for my new company. Whereas I am very close to receiving my Patent Pending status for a much needed tool. After which I'll post a good how-to DIY and maybe offer them for sale if there's enough interest.

Sorry for the delayed reply. I forgot to set the post to notify me of activity. As for UV and scratch resistance, I intend to put clear vinyl automotive UV protection on top. The leading edges do curve in and were done with a heat gun & torch on a sheet metal break. But they can also be curved on a simple DIY jig, just take your time! below is what i used and u an get both panels from one sheet. http://www.eplastics.com/Pl...ACRY26480-125PM24X48
As for the diffuser, it's just sheet metal. The fins can removed if they to be repaired or replaced.
