What are you using to rotate it mate?

 

[MacKiwi]

Is it the force of the water squirting out the holes?

 

[tazuk]

water out of hlt in to sparge arm arm is 12 inch long on each 6 inch arm got 6 1/16 or 1/32 holes wot ever the smallest drill bit lol i **** at that
spacing 1 inch-1 inch-3/4-3/4-3/4-1/2-1/4 each arm

yes its like a jet of water as you can see at each end of sparge arm 2 holes close helps it rotate

Is it the force of the water squirting out the holes?

I made mine out of 8mm copper tube using end feed fittings and rotating on an 8mm compression coupler. It weighs almost nothing.
I am having a brew weekend so wil post some pics and try and get some accurate measurements on flow rates etc.
