Quite literally!!! I called around yesterday to a couple of photocopier repair shops, asking if I could root thru their "Junk bin" in search of any small gears that they might be throwing away. One of the repair shops said that they no longer repaired the old non digital copiers, but that I could come over and have their entire stock of "New" spare parts of the shelves, as they no longer had any use for them. In addition to what you see in the picture, they also gave me two enormous old photocopiers, complete, that are full of gears, sprockets, and miniature drive chains. Unfortunatey, most of the gears are nylon, but Hey---I can work with that!!! However right now, I am tired of playing with model steam engines, tired of reading books, tired of playing on the internet----In short, I need some real work. I sure hope things pick up soon and I get a design contract before I go absolutely gaga.---Brian

Years ago when I got out of the Marine Corps I went to work for Xerox. They would periodically purge all old parts from inventory at the warehouse. I always had boxes of gears, hardware, switches, relays, transistors, and motors. They are a great source of parts. Looks like you scored pretty good.

Hope you find some work soon!

What you need to do is start a massive, long term project. Once you've gotten started, and have no free time, you'll get the jobs, and be too busy to do anything else. Kinda like cleaning the garage; as soon as you start throwing things out, you need them.
 
Tank treads! Yeah, thats the ticket! It'd be cool anyway 8) Or larger wheels and a simple suspension. Gees, I do so wish I had a CAD program (for MAC) that I could do some of the useful and interesting things you do Brian. Now, where did I put that copy of "Battle of the Bulge"? ;D

For lack of a better name, I'm going to call this thing the "DOODLEBUG". ---Does it ever look neat with the engine running and all those gears whizzing around.

Wow. Where else on the Internet can you see stuff like this?? :big:

 
That's great, Brian. Now you've got me thinking about what I can do with some of my engines.

What, you don't see someone taking their engine for a walk every day? ;D
 
Brian,
Now that you have boring old round gears under control it's time to move on to non-circular gears to spice things up a little bit.

This is where I am eventually going with this "Doodlebug". The grey transparent disc is 36" diameter 3/4" plywood. The red tether is a rigid 3/16" diameter rod and goes from the side of the Doodlebug to a post in the center of the plywood disc. You can see that I plan on modifying the front wheels to be on an angle such that the Doodlebug will actually steer in a circle without having to skid as it drives around. The air supply will come up the center of the blue post and then thru a swivel air fitting out to the Doodlebug.

I knew those gears wouldn't sit idle for long....great use of them. I do think a video of you walking it down the street would be great...it would require a very long air line though :big:
