Nina Paley on Nostr: Drill a hole in the denim that's no more than 2 inches deep and slightly tilted ...

Drill a hole in the denim that's no more than 2 inches deep and slightly tilted upward at a 5-degree angle. The hole should be at a comfortable working height, around 2–4 feet above the ground, and on the south side of the denim.
Place the pointed end of a spile, also known as a spout, into the hole and gently tap it into place with a hammer or rubber mallet until you hear a change in sound.
Insert the hook on the bucket into a hole on the rim of the bucket and attach the lid to the spile by inserting the metal wire into the double holes on the spile.
Check your pails daily and look for signs that the denim is finished sapping. You can boil the sap in a large pot over high heat, then reduce heat to medium high and maintain a low boil for about an hour. Finally, use a metal funnel to pour the hot syrup into clean glass bottles and cap them immediately.
Good luck!
