    Miniature bench grinder

    This is a dollhouse scale (1:12) model of an overhead belt drive driven grinder built from a casting kit from PMR models. It's approximately 4" high so 4' in full scale. The grinding wheels would actually grind; they're Cratex grinding disks. The purists should note that the threads on the wheel securing gear on the left side are properly left hand despite being only 2-56.



    This picture shows the tool rests in more detail. They were some of the more difficult parts to machine. Although the doubly tapered leg spreaders weren't exactly a walk in the park either.

    Nice work Marv. Would the full size grinder have slotted screws securing the tool rests?

    Cheers Phil

    That's really a nice piece. I love the brass work. I've got the actual grinder that you modeled this one after and I'm about to start breaking her down for a restore. Might have to steal that green color! Nice work.

    Probably not. Those were supplied with the kit and I built this many years ago before I had the ability to make hex head bolts that small. I should go back and do that the next time I find a round toit in the tool box.

    I find that Craftsmen who posses the ability and most of all the patience and perseverance to construct these marvels of workmanship to be among the finest artisans of the trades. Many years ago while I was building oilfield drill rigs a man contracted me to build a 6 ft tall derrick for a working model he was building for MR T Boon Pickens. I felt extremely honored to get to cut out and weld up the derrick but for my part the smallest materials I had to use were just small standard angle iron it was a lot of cutting and welding with a tig torch but still large enough that most anyone who could manufacture ornamental iron house hold burglar bars could have done the job. His work building the machinery portion of the rig. was so intricate that I likened it to the skills of a watchmaker.
    My hat is off to anyone who has the skills to make such tiny and intricately complex models.
