Hi, i am planning on building a hive lift on the order of the EZy loader, i have one issue with my design, i plan to reach at least 14 feet from the main mast. This design issue i'm having is what to use for the main pivot point. I am thinking either a mower spindle but not sure if i can find one big enough or maybe using a 7000 lb axle spindle with an idler hub. I do want bearings for ease of movement so a pipe sleeve is out. any thoughts or idea's will be appreciated.
