|Editor's Note: When Blogger stopped supporting FTP it pretty much threw a big monkey wrench into all of my online publishing. The service seems to be plagued with bugs and I suspect we are seeing the death of another once-relevant web icon. The same thing happened to me when Yahoo bought e-groups, and again when geocities ceased to be. (Frustratingly accumulating multiple accounts as all things become Google) JohnnyPayphone.net has become my online resume and is updated rarely and by hand. Chicagofreakbike, which was updating only a few times a year even when I was in Chicago, has slowed way down and is being updated by hand. It still remains, as many people tell me, a great place to poke around for ideas and so it shall survive. My blog, which is ten years old this year, has ground to a halt as I attempted to migrate it to johnnypayphone.blogspot.com but I forgot and updated the old one by hand and I'm just finding the whole blog thing to be less relevant these days as I use the internet less and less. Pennyfakething.com has been giving me a "migration pending" beachball on the blogger dashboard for several months now. I intend to keep the site and update it by hand as I develop my pennyfakething designs. My great-grandfather's diary, The Diary of Fletcher Ames Hatch, is the only one that really works for me on blogspot because I still have the source material in hand and can trust my site's content on the servers of a company that may go the way of geocities. I really only put it there, and at twitter in order to trickle it into the internet cache. Meanwhile for aggregating content that is not my own I find tumblr to be quite easy to use and you may enjoy johnnypayphone.tumblr.com & Steampunk Vehicles. As I find myself busier and more active in real life I update less and less, and for this I apologize to anybody who may be out there enjoying any of these fine online Johnny Payphone products these last ten years. The world is a drastically different place than it was then, and so is the internet, and so is my life. I always like answer emails about wacky bike design and can still be reached at payphone at primate dot net.|

Screw Drive Roundup
I have long been fascinated with screw drive & cannot wait until I am mudbogging in one of my own creation. The conditions and budgets neccessary to make this a sane project have only aligned a few times in the past century. You can read a detailed history at the wikipedia page.
Apparently the Peavy family had two as early as 1907, one steam-powered. The advantage in the agricultural field is that it plows as it goes.
The earliest usage was for agriculture, such as the Fordson Snow Motor:
As you can see they were putting these things on Chevys by the 1920s.
Even Tucker got in on the action:
During WWII the Nazis had a version:
The Russians tried out a few designs. You can find more history here.
My favorite is the ZIL version. Seeing these videos is what changed my vision from a isn't-that-clever art car to a mud-boggin' badass. I wanna take it to the Redneck Yacht Club!
During the 60s Chrysler developed the Marsh Screw Amphibian:
The Marsh Amphibian and its massive, unweildy descendant the Riverine Utility Craft were evaluated by the Army's Mobility and Environmental Administration. There is more weird locomotion at the Army's great website on the subject.
....aaaand of course Chrysler Defence Operations Division, given enough time and enough money, will eventually come up with what I deem "Operation Hatful Of Assholes":
...ever heard the expression "A camel is a horse designed by committee"?
Apparently Samuel Cody (of the Cody Manlifter) submitted a patent for an augur drive tank, but the government didn't bite. From Shusharmor come these pictures of a model of his patent:
There was a Dutch version called the Amphiroll so named for its high sideways speed. Amphibiousvehicle.net is a great site, especially if you wanna see some bad ideas.
For more bad ideas, see Unusual Locomotion.
Of course, there are many modern augur drive vehicles such as those used for arctic exploration. They aren't as much fun to look at so find 'em yourself. There's also the Tyco Terrain Twister R/C car and Segway's robot platform. Some augur drive tanks have appeared in various video games. There's a Survival Research Laboratories robot that uses the technology.
Vintage U.S. Augur Drive
In the winter of 1941-42, the Americans began feverishly to increase fleet that can move through the snow - it seemed that at the Alaskan base should not encroach mad samurai, not the Kremlin's man-eater, not a madman Fuhrer, and then all together. Has not spared it the urgent creation of snow machines and party shnekohody. In particular, a farm tractor was equipped with two screws and started testing, but soon he was gone so quickly that not even left behind no evidence of TTX ...
