That's funny, just today I kicked off a machining job for an adapter hub for my 5.5 h.p. Honda. I looked underneath and saw that I had about 3" of keyed 7/8" shaft available above the pump. I will try to mount an automotive crankshaft pulley, aleternator, and serpentine belt (which is on-hand, thus free) gell-cell battery (again, on-hand) and perhaps worklights (not that I work in the dark alot, but since I have a pair of those chrome deals off a utility truck on-hand, what the hey. Even if I don't use this on-board stand-alone lighting for splitting, it is a capability I don't have now but will then. With 12VDC on-board, I don't think electric start will be far behind.
I've hatched a plan to make my splitter a multi-use tool. So far I have on-board my chainsaw tool box (wedges, files, screnches, spare chains, tach, sundry whatnots), a gallon of bar oil, and my brush cutter (FS76, I think). Next,I'm building a side rack I can mount two cased saws or three uncased ones and a 2.5-gallon fuel can. This stuff, plus work lights could turn this thing into a real workhorse. And yes, I'm being mindful of wheel&tire/bearing loading as well as the "when does it cease being a splitter and start being a trailer" deal. I want to stop just shy of having to tag and light the thing. Currently, the thing enjoys the comfortable life in my wood stove heated garage, so all I have to do is hook-and-go when woods-time is right.
Or I could throw in the towel and leave it as-is. The feasibility could tank at any turn, I'm fully prepared to stuff my parts back on the shelf.
