Update: July 2010 - Been away from my Lego models for some time, but I have had a few requests for a video. The only one I can find was shot on my cell phone back when cellphone videos were new and crappy. It's all I have of it in operation, so I hope you enjoy.
UPDATE: August 28th. The ride is complete! I have not got the new pictures done yet, but I have added a couple of the lights on the front of the Zipper. I will be setting it up on our driveway next week to take some well-lit pictures. This has been a very fun project, and I am happy with the results. Functionality is identical to the real ride.
I have started my next ride, which is a HUSS Enterprise.
I have received a number of requests to purchse my models. I am willing to sell them, as well as do comissioned work. IF you have a ride that you would like built out of Lego elements, or if you might be interested in purchasing an existing model, feel free to drop me a line at firstname.lastname@example.org to discuss all the details. If you are interested in having your company logo, or other signage built, I am able to provide that kind of service as well. Again, drop me a line and I can share the current portfolio of work with you.
Thanks for all the kind emails, and compliments on my work as well!

This project is almost complete, But I will not be making it to Brickfest this year alas.
I had to completely redesign the bogey wheel section from a three wheel system, which used the friction of the bogey to rub against the rails, to a 4 wheel system, that is much like a steel coasters wheel set-up. This allowed for a much smoother flow to the bogey train. I have mostly everything working, just have to build a control point to adjust the speed of the main boom. The cars really whip around this thing, and when the boom starts spinning, it creates the identical ride motion as the real ride. As far as things that still need to be done, they are:
Finish car detailing and doors
Boom wiring must be concealed and cleaned up
Boom motor detailing and control mechanism
Drive belt adjustmens and tensioning
Queue and signage
In answer to some of the questions in the reviews below:
As far as selling this, it is a possiblity, but not before the Toronto Hobby Show in November.
No this would not become an actual Lego set, as not many would be able to afford this many elements. Not to mention the shipping costs on 200lbs of Lego elements would be obscene! ;-)
Here is my current Project, The Zipper. The Zipper is a one-of-a-kind carnival ride that is still in heavy operation at many carnivals and amusement parks today. The reason this ride is popular is that it is both thrilling for the guests who ride, and a real easy two-man set-up for the the carnival employees. The design of the ride is very unique in that it is essentially a large boom with 'bogeys' mounted to a frame, which allow them to move very much like a bulldozer track. This boom also rotates, causing a double spinning effect on the bogeys as they round the ends of the boom. The cars are attached to the bogeys in such a way to allow them to be able to flip end-over-end, at the whim of either gravity, or the forces at work as the boom spins. The Zipper has a reputation to be a real 'puke bucket' as guests who are susceptable to motion sickness soon find there chilli-dogs coming back to haunt them. An interesting thing to note(and I read this at David's www.ride-extravaganza.com - Thanks David!) is that the first few Zippers that were released, had a much faster boom speed, causing a REAL vomit problem. It was later reduced in order to increase the rides popularity, and prevent it from getting a bad reputation from the start as 'NO FUN!'.
The translation to Lego was interesting, with one of the most difficult parts being the design of the frame/track that the bogeys travel around. I tried a few different geometries using 1x4 hingeplates with 1x2's on them for the round end of the track. I finally got something that would work within the dimensions I wanted, and began building the boom. The bogeys have a three wheel system on them that keep them traveling in-line around the track. Each of the wheel assemblies is articulated to allow them to bend around the curve. The four 'wagon wheels' as they are called on the real ride, were made of mostly plates and hingeplates, with slopes to form the cable grips. I had to use non-Lego thin, clear, plexiglass to form the rims that the 8 9volt Lego motors will rub against to drive the bogey train around the boom.
I built the basis for a trailer to start the actual boom support column, which is articulated to allow it to fold down to the horizontal position for travel. Because current needed to be supplied to the boom, I created a commutator out of some copper pieces, and some gold-plated speaker terminals. The boom support itself, has a back-bone made of technic 1x10 bricks pinned together. This will support the weight of the boom when mounted, preventing it from breaking apart with the almost 25lbs the boom will be when all cars are attached. I had to use non-Lego bearings in the boom support hub, simply due to the weight.
Thanks for having a look! Any questions or comments are welcome! :)
IT LOOKS ALMOST EXACTLY LIKE IT I WAS WONDERIN HOW I WOULD GET IN TOUCH WIT YOU CUZ I WANNA KNO HOW U BULIT THE ELI BRIDGE SCRAMBLERN THE TILT-A-WHIRL N THE ZIPPER N THE FERRIS WHEEL?
IM ALSO AN AMUSEMANT LEGO BULIDER BUT MINE ARENT THA BIG PLUS I THINK U CAN BUILT A ROUND-UP
Wow, wow and wow again.
All of your creations are amazing technical achievements while also capturing the spirit and essence of their real-world counterparts beautifully!
What a great choice for your subjects too... LEGO and amusement rides together... fun+fun=tonnesO'fun!
...Makes me wish I was 4in tall !
