At the turn of the last century there was a company advertising tiny tools as watch charms. My grandfather being a steam engineer and plumber had this wrench but I think there was a hammer offered also (I'd have to look up the ads).
LOTs of precision work has been produced on 6 inch Atlas lathes. They filled the niche that the little Asian lathes now occupy ... and were much better, IMHO. Of course I'm prejudiced since my first lathe was a well-tooled 6 inch Atlas
Craftsman 109's are actually produced by Dunlap, not Atlas. Dunlap sold the same model as well, but they mainly made them for Craftsman. The Atlas 618 would be a huge upgrade to the 109, in weight, rigidity, normal backgear, and a larger spindle (Planetary on the 109, a weaker and more fragile back gear setup then the 618, but it is more compact). I used this lathe before the SB came along, it did everything I needed and for $75 I can't complain. I know that thing in and out, washed every part by hand in the basement with Kerosene ans reassembled, the right way. Most screws and parts got antiseize, lithium grease, black grease, or light oil depending on the application. Or at least I THINK I did it the right way Time will tell.
Since the 13" was wayyyy to big for the basement, I keep the 109 in the basement for winter jobs. It's quieter than a mouse, can hardly hear it 15' away and can't at 30'. With a 1/4HP Emerson electric motor it made a perfect combo.
The real downside is the small spindle, the chuck will bow away on mild cuts in steel, but a spring cut or two and a little strip of 400 grit sandpaper you can get small parts to tenths, if your careful!
The 109 is a good lathe, if you can work within it's limitations.
Oh, and the pics above were taken with a jewelers loupe in front of the phone, a great trick for adding a little detail with lower res phone cameras.
Those are sweeet! I wish I had a picture of it to share but many years ago I was at the "Cabin Fever" show in York, PA and saw a full-on overhead belt driven machine shop "doll house". The tools in this thread would have fit on the benches well.
