there she is. she stands a bit tall. 37" total. but as you can see the neck is pretty damn tall. so we can cut her down a bit.
I did out some of the math for the cone:
If we draw up an equilateral triangle..with both of the equal sides having a length of 32-13/16". we then use a massive version of Greg's jig (2x4?) to cut our arc from equal side to equal side. oh, and an angle of 65 degrees between the two sides.
we then bend it? how? dunno..but i did it up with construction paper haha, and it comes out to a nice lookin cone.
as far as the bubble plate action. microbubbles go through the center of bubble plate one to be directed towards the outer walls with cone 4. the bubbles travel up through bubble plate 2 and are directed towards the center of the skimmer with cone 3. the bubbles then smash into disc 3 and gently rise to the top.
no idea how much it will cost. ill look into parts etc if we settle on this or somthing like it. i know its a bit complicated...but logically it should do the trick and then some. the good news is..this will be a tough one to finish in a day, we may just have to start puttin a few down in the AM! haha ehhh niiiice
