I'm trying to save a little money and found an old Wille dual planer mast but it did not come with a mounting base. The mast is 1 1/2" OD and the Big Jon Mast base is suppose to fit a 1 1/2" mast. The mast base ID is actually a little less than 1 1/2" ID and the mast will not fit into the base. Just wondering if anyone has ran into this problem.
