Where can I find a (very) small auger?
I have only found this part in the form of parts in toys. One of the toys is a demonstration of an archimedes screw water lifter, which I have obtained but it's not long enough to be terribly practical. The other is from an old toy grain auger that isn't made anymore. Similar ones are still produced, but the augers are made of plastic and aren't entirely straight or flush with their enclosure.
The best one I've found is in this toy:
I'd like to know of any manufacturers that make augers similar to that, whether they be metal or plastic. I'd rather not blow money on expensive antique toys and destroy them.
