I only do 1 - 1 1/2" on my health spouts. seems to work great.

LOL Kevin, can't say I have, I have too many hens I wouldn't want the others to get jealous :lol: :lol: :wink:

I tap 2" max. But at the nys maple conve. Cornel univer. said you can drill 3" or deeper " size of tree matters" just decrease the number of taps by 1. and tap opposit each other i.e. 2 taps. max per tree.
Has something to do with negitive pressure in the tree and all that 50 yr study they've been doing.
