Setup for mechanical biodynamic preparation stirring?

Hello,  I am expanding my efforts in biodynamics enough this year to warrant looking into building a way to stir the preps mechanically.

Initial thoughts:

Wooden frame to hold a machine that points into a bucket, like the large & expensive BD stirrers in Europe

Looking at concrete  / paint  / “Mud” mixers with reverse funtionality

Something from a battery-powered tool would be convenient (but an hour stir time might not be practical)

...but I'm sure there's more ingenuity here to draw from - thanks for any info!

Dave I don't know how much help I can offer.  I've done biodynamic off and on since the late 80's.  This very subject has been the cause of many lost relationships and some out and out very harsh worded arguments.  I once set several buckets with well fitting lids in a small tote and placed the rig in the back of my pickup and drove it around all day, it seemed to work just fine.  I know of another that used an old aquarium pump, again it seemed to work fine.  I would try some kind of wood stand or bracket thingy using large hose clamps to hold a drill (battery or electric) fitted with a paint or drywall mud paddle blade.  How about holding the drill in a bench vice and using scrap wood to bring your bucket to the right height??? (nothing to build) !!!

Good luck, please let us know of how things turn out.

Peace

I only understand Biodynamic as agriculture so I don't understand how your question relates to agriculture.  Am I missing something?

Anne, I'll give this a try, please bear with me.  There are preparations based upon plant materials and tree barks, mixed and aged sometimes in various animal byproducts (horn, intestines, etc.) after aging these materials are used to make a "mother tincture" for lack of a better term.  A measure of this liquid material is then reduced in another measure of water-this I think is where Dave's question comes in, on the method of mechanical stirring instead of by hand for an hour.  Most of the 500 series preps are for making an aid to composting, others are for leaf feeding sprays.

Well how did I do?  I so hope I didn't make the "waters" more muddy for you.

Peace

Thanks, Deane.

Yes, that explains it.
