I am in the process of rebuilding a wood splitter that we built about 23 years ago. I would like to add a boom to the splitter. Currently I have a mobile "engine puller" that I use to lift the wood onto the splitter, but I would rather have one as a permanent attachment. The majority of the wood I split is 36"-60" Poplar plus some large Elm, Black Locust, and Box Elder. We take the big stuff no one else wants or can handle. I am thinking of using a car or truck axle as the pivot for the mast, and would like to leave the brakes intact when mounting it, so they could be hooked up and used to control the speed of the swing as well as to be able to lock the boom in position. I will use both hydraulics as well as a winch on the boom for draging the wood to the splitter as well as raising it up for placement on the splitter. My question is has anyone else built a boom like this, and what is the best way to mount the axle/hub assembly,and still be able to use the brakes? I'd really rather not "re-invent the wheel" if I don't have to.
