How about a miniature bowling alley, with pin setting machine and ball return? They have a full sized one operating in the Heritage museum in Muskegon Michigan, (home of Brunswick) and it's a gas to watch.
 
There was a guy here in Maine that built a hay baler that ran off one of his gas engines. It was about 30" long and made bales out of grass cuttings about 2x3 inches. He would run it at shows and had a box of grass clippings that he hand loaded into the hopper.

It always drew a good crowd to watch.

My vote is for this. I would imagine that the mechanism is very complex though.
 
Hey Brian
why not a mini lathe

all the plans are here
of course I could not attaché plans here they are in your
rogers email

How about an engine driven marble machine? There are varoius designs of marble pumps floating around on the web. You could build as complex marble machine as you wanted. Heck, start simple with just a pump and keep adding to it whenever it strikes your fancy.

Brian,
I do like the idea of a pick and place machine. Given a background of automation design, it would give you an opportunity to integrate a gas engine with electronic controls. Use an engine of your picking for power and a PLC for control. You can use multiple PTO's for mechanical movement and even one to turn a small generator to power the electronics. Completely self sufficient. Crank it up and let it amaze your potential clients. Integrate common automation components like prox switches, ball screws, linear way and bearing, servos or steppers and a chain and sprocket or two. Even put a light curtain on it to sense when you reach in and move a pick part to try to trick it.
 
Jwcnc--You're imagination is running away with you. When I said automation, I mean simple, mechanical automation. You are talking about many thousands of dollars worth of work.---I reserve that for my customers!!:D:D

Brian--- how do you like the mini lathe plans???
 
I would like to see a single-cylinder 2-cycle water cooled marine engine like the ones used in Newfoundland fishing boats with a large flywheel and timing lever
. Simple, cute, fun to watch and hear. - Bill McKinley

Billy---That would be a "Make and Break" engine wouldn't it? They are different than a hit and miss.
 
Brian .What about an helical screw lift for your ball machine,low constant torque. visualy interesting. put it in a glass tube or guide the balls with a couple of rods.

I have come up with something. It is in the early planning stages yet, but will involve mechanically automated "material handling"--Moving objects (possibly cylindrical) from one station, thru a couple of other stations, and then return to repeat the cycle.---Brian

Sounds very cool ( picturing automatic beer dispenser that gets beer from fridge and returns empties to trash.)
 
Brian:

Here's a film from a 1936 Chevrolet production line that shows the frames being assembled. The section I'm talking about is about 20 minutes into the attached link.

It would give anyone involved in industrial safety a heart attack watching those guys standing in the middle of all that unguarded machinery. They didn't have much time to fit the parts on before the cold riveting heads came in to permenantly attach the part. If you watch closely you can see that all the equipment is mechanically driven becacuse you can see the drive shafts turning.

A simplified version of that would be right in line with what you are talking about.

It will probably be derived from something in here----

these are very cool

I would have prefer all physics and no motor

still a great achievement
:eek:
