motorised fly sparge

[Euclid]

Some 45 years into my brewing hobby I decided to investigate an ongoing argument about fly sparging. Commercially it used because it is very efficient, even before shallower lauters and compressed air use with finer grists. I designed and built one that doesn't rely on the water flow to turn the arm; usually resulting in too rapid a throughput of sparge liquor.

One of my grandsons uploaded my efforts with instructions.

That looks like it works great. But why bother with a motor when you have a spare grandson to stand there and rotate it?

I like it, be good to develop it so that you could lower the arm into the mash and use it to mix the mash

Very nice!

How does it work with the 'o' rings? Are they in between the T and the straight pipe?

Very cool!

I always thought the water pressure alone with a sparge arm would cause it to spin though?

Edit: sorry I should learn to read, you mention that makes it spin too fast

Maybe you could make one of those spinning mash paddle things too
