I have poured many elaborate house foundations, countertops, sinks, etc. I know how to build things inside out and work backwards. I know what release agents are, I have done some sand casting. I do not need help there.
I simply do not know the shape of the required flow forms. There are many different styles, they are so unique that they their shape cannot be conveyed from a simple picture. They cannot be mathematically described either. They are unique. Sure I could guess and experiment, but I have too much other work to do. We farm full time, about to start the cropping season.
I just want to buy some plastic molds and get going. The fact that I saw some at a renewable energy fair 20 years ago leads me to believe there are some out there somewhere. I am trying to say this politely, but sometimes I find the biodynamic "industry" keeps it's cards close to its chest and rarely share info for the diy type of people. for example, two day courses at $1000 a day may be good value for money, but my farm cannot afford that. Shipping pre made molds from new zealand is ridiculous. That is why we grow organic grain for our animals because we do not believe all the imported "organic" feed from china and india is very organic after travelling around the world. I know this is off topic, but please, someone must know someone with some molds for sale.
thanks in advance for any leads. george

You can use a large block of wood and make the plug by carving the shapes you desire in that then use a vacuum bag or table to create your plastic mold (you have to heat the plastic first) since it sounds to me like you just have to have a plastic mold as opposed to a fiberglass or rubber one.
Keep in mind that the theory is still under investigation and not fully proofed at this point in time.
They do make pretty water features though.
For the simplest form get two hard balls (rubber or what have you) and place them touching and press into a wet sand bed, when you remove them you will have a reverse of a nice flow form that you can fill with plaster to get the plug for mold making.
