(bought at local home improvement store) I then drilled with a 1mm drill bit. I did too many holes the first time so I pluged some with epoxy. ( going to plug a few more than what is in pics) What holds the arm in the wood is rubber o rings tight to the tubing. One on the bottom and two on top. The tubing I had was too big for the copper so I just clamped down with a stainless hose clamp. To stop up the end I just pinched it with pilars and folded over.
really liking this cheap DIY for fly sparging. You said you thought you drilled too many holes. What do you think the optimal number or distance between holes should be?
*edit* just realized this was over a year old. Hopefully, he's still around
