Hi All
To bale pine cones you could look at vintage farm baler they used in the olden days , they are built kinda like that one you build might give you some idea top inprove the one you built they were wooden . You know they make a baler for loose straw and loose hay that is pulled behind a tractor, maybe you could find a older baler and improve and it not so big. These were built in the 60 and 70s. Just some ideas to think about good luck :licking:
