Bale needles are used to insert twine to change the size of the bale or to attach items to the bales. They are not usually available for purchase but must be custom fabricated. They must be long and strong enough to go all the way through and out the width of the bale. Some are made to have multiple functions (push/pull) while others have single functions.

Another custom made tool that is used to beat the bales to straighten out a wall. Once the bales are in place you can use this to get a bale adjusted in the wall.
T o make it yourself, use a block of wood (preferably 6” x 6” x 12”) and securely attach a wooden tool handle to it.
