It's about that deep. Can't remember the bit size, but it's big enough for my spile and that's all that matters.
Here's that elderberry growin by my barn. Warning! You better be sure of your plants before you do this!
If you don't have a barrel that is food grade, you can use any container that is food grade. Some people use 2 liter pop bottles or 5 gal water jugs etc.
I like the simple cut but I did do a couple that fit as below.

What about frozen water on in your bucket?
Here's some frozen syrup that is in the finishing pan. Do you think the ice has no sugar in it????
I've seen TV shows on maple sugaring where they throw the ice out because they say "It's just water. the sugar stays in the liquid" They then dump the ice out on the ground and keep the liquid. I've also been told by others that the ice doesn't contain hardly any sugar so it's ok to get rid of it. However my picture of near finished syrup above tastes just as sweet as ice cream! So I think the frozen water in the bucket at left still has sugar too.
Keep the ice! You're throwing out good sap if you chuck it.
