    Default Tapping Depth Poll

    How deep do you drill your tapholes? Only one choice allowed...if it's variable, give the average.

    Does tapping depth correlate to how fast and we'll a tree heals or is that just all in the trees health? I noticed that some trees seem not to heal at all sometimes, is that from tapping too deep. I try go deep on large trees to end of spirals on bit or close which is about 1 3/4 to 2" and shallow on smaller ones probably 1/2 to 3/4.

    Usually between 1.5" and 2", so I picked 1.75". Any time I use some kind of stop device the shavings don't seem to fly out as good as without a stop, so I don't use one.

    I thought the same. tried a depth stop.. then tried just tape around the bit. same issue. I did take the time to file a mark around a bit once.. it worked decent as a visual guide

    I usually put a piece of 5/16 tubbing down on my bit that will allow for 1.75" of tapping depth. On a "normal" (12"-18") tree I'll stop it a bit before my stop. Those big burly trees I'll bury it, and the 8-12" thin skinned trees I'll only go about an inch

    1.5" for us. We tap with a .224 tapping bit, using the DSD spouts for 3 years now. Tap hole healing or compartmentalization is evident quicker than when we used a larger bit and also drilled 2" deep.
