Step 2: cut sheet metal to shape

shaping was conducted entirely with handtools, a shear and a nibbler. at least 10 hours and many blisters later the 768 sided outline began to look like a reasonable approximation to an approximation of a fractal.

the thing they don't tell you about fractals is just how sharp and dangerous they are. i mean, you think you have a pretty good grasp of the mathematical analysis but until a piece of metal with a very high perimiter to surface area ratio tears into your flesh, you're really missing intuitive appreciation for objects that lack continuous derivatives almost everywhere.

<p>While the pie is amazing in and of itself (my jealousy knows no limits - having nut allergies SUCK around the holidays as my family makes absolutely amazing pecan pies. There are days I seriously ponder the pros/cons of saying to heck with it and having a slice, after all, I've GOT an epipen... haven't buckled yet, but the idea is always there) the part that has me furiously scribbling and trying to work out some details is the giant oven you created. I'm suddenly seeing potential for backyard pizza parties where one pizza really IS all that is needed for 20 people! Or perhaps an epic brownie to end all brownies? </p>

<p>This is super cool, and now I want to make decorative fractal art!</p>

That's just totally AWSOME !!!!<br>Thanks so much for sharing it all, the PIE PAN, the OVEN , <br>&amp; most of all THE PIE !!! Sincerely, Jus Beachy
Beautiful pie! Granted, you've achieved a pie with a more crustacous scaling law, but how do you serve it in human-sized pieces, assuring each diner a similar quantity of crust? The problem would be easy to fix in a purely mathematical sense, in the same way that a sphere can be dissected and reassembled into two spheres. The trick doesn't work for real representations of spheres, and sadly, probably wouldn't work for real pies, either. :( Maybe a Sierpinski gasket-shaped pie pan?
Sierpinski gasket pie...<br><br>Maybe a Menger sponge cake (or Menger spongecake, w/e)<br><br>Of course it would soak up a lot of rum (infinite surface area) but would not be very filling (with zero volume)<br>
I am from England, I have ordered a bag from brandbagsales.com. When I receive the product. I find it is not the color I like.They change the bag for me immediately for free. The service is very good.

Examine the soles of your shoes. Note where <a href="http://www.cheap-uggs-boots.com/ugg-mini/" rel="nofollow"><strong>UGG Mini</strong></a> wear has occurred. Most people seem to be amazed that their shoes wear at the rear outer corner. Most <a href="http://www.cheap-uggs-boots.com/ugg-mini/" rel="nofollow"><strong>UGG Mini boots</strong></a> rearfoot strikers will wear at this part of the shoe. The reason for this, which someday, somewhere a funded study will prove, is that for most heel strikers it is the point <a href="http://www.cheap-uggs-boots.com/ugg-mini/" rel="nofollow"><strong>Mini ugg boots</strong></a> of first contact of the shoe with the ground. Most people walk and run with their feet slightly rotated from center. Runners, however, also have what is called a narrow base <a href="http://www.cheap-uggs-boots.com/ugg-mini/" rel="nofollow"><strong>Mini uggs</strong></a> of gait. A narrow base of gait means that the feet contact close to the midline of your body. This creates additional varus (tilting in) of the limb. This results, for the rearfoot striker, in the first point hitting the ground being the outer corner of your shoe. Forefoot wear <a href="http://www.cheap-uggs-boots.com/ugg-mini/" rel="nofollow"><strong>ugg 5854</strong></a> may point to an individual who is a sprinter, runs fast, contacts the ground with the forefoot first or all of the above. Uneven forefoot wear may show where one metatarsal is plantarflexed relative to the others or where one metatarsal may be longer than the others. In the presence of significant forefoot wear, you are at risk of stress fractures.
i understand what you are trying to do with the whole &quot;filling dominates crust&quot; thing, but wouldnt the midlle be dominated? i guess you could solve this by making the center a bit thicker than the edges. Please reply, as i would like to know what you think about it. Thanks, -Darthpotato
i bow down to you.&nbsp; totally incredible!!!!!!<br />
You guys are incredible. Awesome mind power combines with the love of good food. I&nbsp;am going to connect this up to my face book. You guys deserve others to see the true powers of Geeks in action (I meant this in a totally nice way). Have a great Christmas!<br />
a little hard to cut, maybe, but this is genius<br />
<p>Lol - how to instructify a pecan pie!</p>
if i were you for the oven I would take some fiberglass insulation and put that in the cinderblocks to help hold in heat
yummy looks like a snowflake
Awesome! This will be a great way to share my love of fractals.<br/><br/><sub>90% of it will go to waste, though...</sub><br/>
turkeytek, I have just discovered your genius for food. You get an A+ for this one. I'm wondering if another piece of durock under your oven rack would help diffuse the heat enough to avoid hot spots. Perhaps a couple of inches below the rack to ensure good airflow.
that might work, but i'm not sure durock could stand up to the heat. it may even have some plastic mesh inside. i guess a giant baking stone would do the trick.
Or even some strategically placed cinder blocks. D'ya think a large piece of heavy steel or cast iron might do it? Something similar to say, a manhole cover? I might have to make a giant oven. Just because it can be done.
PiMan approves!
HAHAHAHAHA! You look like eric forman off of that 70's show:<br/><br/><a rel="nofollow" href="http://www.that70sshow.com/images/gallery/s4/s4_eric.jpg">http://www.that70sshow.com/images/gallery/s4/s4_eric.jpg</a><br/>
Wait, which one? I always think elf looks like Harrison Ford, but I'm partial. Maybe you were talking about tek. Or the pie? I don't think the pie looks like Eric Forman.<br/><br/><a rel="nofollow" href="http://www.starwars.com/databank/character/hansolo/img/movie_bg.jpg">http://www.starwars.com/databank/character/hansolo/img/movie_bg.jpg</a><br/>
dang! super pie, wall art.... so when are you opening the art studio cafe? cool!
Ewilhelm, you like the edge? (sorry for communicating through comments to ewilhelm, turkey tek!) Turkey Tek, looks delicious! How long did it take to do this again?
a month worth of friday nights. maybe 15 hours shaping the sheet metal and folding up the edge. another 5 hours futzing around with the welder and 9 hours to build the oven, mix ingredients and bake it.
was it worth it, for the pie?
pecan pie is worth anything.
That's... pretty long!
One of my all-time favorites...
how about a mobius-shaped pie next? i really like this, it's somewhere beyond cool
Wow, this is nerlicious! I salute your nerditude.<br/><br/>4 <sup>_</sup><br/>
Finally a practical use of that fractal ho-ha.
It's not true that we didn't have a backup plan. Our backup plan was to make Thanksgiving Jello.
where by jello you mean a soup of pecans, corn syrup, sugar and uncooked eggs.
Incredible! I assume you still have the pie pan somewhere in storage? Maybe once the glow of the Maker Faire has worn off, Instructables could sponsor a Bay Area Makers giant pie eating party? We could host it at Squid Labs, in Emeryville. I'll bet this design would also be useful at more conventional sizes. I know I always fight for the edge pieces of lasagna, brownies, and apple crisp.
It would seem, that for people who like corners, you should make pies of the same shape, but 3-6 inches in diameter. This way, each person gets their own pie, and crust!
thanks. now included is a picture of the pan's final resting place. i'm sure it is still servicable if the opportunity should arise.
is it safe to have that LP hose *in* the oven?<br/>
the temperature in the oven is only 350-400 degrees F. i think the thick rubber hose can generally withstand these sort of temperatures. this hose had an id printed on it that allowed us to look up the temperature rating.
Ace. I'm thinking of a 50 ft. vertical container-pole vat for cooking in now. Food distribution in a $200/sq. ft world.
Incredible, now try doing the mandelbrot set, that would be even more ove a challenge
Dude. sweet project. big food+math+building stuff=very fun<br/>
P.S. That looks great as a wall hanger!!
