Beautiful work, Joe. Thanks for showing us your work.

casting kits for model machine tools make up into fascinating miniatures (I know; I've built them all) that actually work just as the originals did. To see just how realistic they can be, see the video I submitted in this post...

model of steam-era machine shop

J. L. Madill, a genius Canadian model builder, constructed an immensely detailed diorama of a working, steam-era machine shop in which all the machine tools are built from the PMR casting kits.

However, as Joe points out, these are not kits for beginners. (It took me a whole summer to build the lathe) and many of the parts are very tiny. They're all doll house scale - inch to the foot - so imagine constructing a working Morse taper drill and socket at that scale.
