    "Little Job" cement mixer

    Rudy Kouhoupt's "Little Job" cement mixer was featured on the cover of the January 1996 issue of "Home Shop Machinist". I knew when I saw it that I had to have one.



    This view shows the yoke that supports the bucket. Milled from a solid block with shafts turned between centers, it's made me think that this CNC stuff might have some advantages after all.



    Tilted down to show how the load is dumped.




    This view shows the contrate gear that circles the bucket. The contrate gear is driven by a small pinion on the same shaft as the crowned pulley.



    This was my first venture into making "real" gears (and that was a major impetus for choosing this project). I used Chinese gear cutters purchased from Enco and they worked very nicely. However, the 90 tooth contrate gear was a real exercise in tedium. My neighbors commented on the emphatic "Yippee" when the last tooth formed completely and wasn't a half tooth.

    Although I'll probably never complete it, my idea is to incorporate the cement mixer into a steam powered bar set where it will make martinis rather than concrete (accompanied by a steam hammer to crack nuts and pit olives).

    WoW Marv, Great build! Thanks for sharing this with us. Love the idea of the martini bar set...hope you take it to the finish line. Can't imagine how you are going to pit the olives. If it were for Gibson's you wouldn't have to do anything to the onions except pick-em up and drop them in...

    The gears turned out excellent and understand the Yippee after 90 reps. Curious about the drum construction, seam and mixing blades and the beautiful bowl on the back end!! Looks like some kind of weld as there are no signs of external seam or fasteners.

    You always amaze me...Thanks Very Much! ~PJ

    My very first thought was martinis but then I remembered James Bond said "shaken not stirred".
