alot more than panda film or mylar would cost you
Ghetto FABULOUS! Lots of great ideas come out of the constraints of poverty. Did rich people come up with the blues? Or, chitlins n hog jowls? Or recycling? HELL NO- they've had it too easy to be forced to improvise!Great thread Tystik :)
Im using a Space blanket I found in a cheap 1st aid kit. How Ghetto is that?;)
Very reflective!... Could it be Too Reflective?

Cheap!
Panda film isn't specular; it's a diffusion surface, or 'soft bounce' as they say in film and photography, which is the very thing I'm trying to avoid. Mylar is what I've been working with up 'til now, but I want to remove the inherent floppiness and difficulty of maintaining a good smooth reflective surface
i believe this happened because the clay pebbles stayed moist right to top and roots developed better as a result,, great for me,,i most recently learned this tho,,,,, i had got some rooted clones right outta a cloner and put them directly into coco pebbles with canna agua nutes....for about 4-5 days i had them goin with no external root growth coming outta parts,,, well, i put my cut out circles of panda film white side up always on top of plant medium to prevent algae growth before it started...WELL, unexpected results here! the root growth got better and the roots were outta the bottom of their 6 inch 0ne gallon hydro pots withina couple days....
PART TWO,,,i got five new clones and did them same way, BUT from day one with panda film on top this time,,, well, 4 days later i have roots 2 inches out the bottom already,,, i could tell these clones took right away,,,fyi, i am new to using clones, but like it alot,,, just plop them into the pot n mediumi choose n gro, easy!
that aluminum would be costing around a few hundred dollars wouldnt it? isnt a lb a couple dollars now?..... depending how thin u can buy it and still do what u need it to do strength wise
LOL the funny thing is, I've been chasing a quote for weeks now and no one will give me one! Ain't that a switch? It only needs to be .010 thick or perhaps a bit less, I'm going to put a couple folds in it to help keep it rigid.
You're just not going to get a real quote on that, ttystikk. The truth is, polishing aluminum is something that is either done by the end customer or something the end customer has done by machinists. Your idea of folding the final product would be... problematic in terms of customer satisfaction.
Polishing (buffing, really... polishing is ongoing preventive maintenance for aluminum buffed to a mirror shine) is a boat load of work, but still something you could do yourself with a few tools and supplies (and maybe a bucket-load each of time and patience).
Get your cut to size pieces mounted to some thin, stiff board; this is structural, so I'd lean toward gluing onto plywood for this step. Securely mount each board and follow the instructions of better buffers than I: http://www.caswellplating.com/buffman.htm.
On further reflection though, have you looked into first-surface mirrors? If you can foot the bill, I suspect you'll have a better shot at feasibility using this approach.
Ah... that stuff.
Something like 94% reflective, with no hotspots...
Wow. These people are really proud of their work: http://www.specialty-lights.com/reflective-sun-sheets.html
This stuff still looks suspiciously like the radiant insulation sold in roll at the local Orange Depot.
Of course, if you're on the hunt, perhaps something with a heartbeat is more your style:
