some of these look like they could be cut on the bot, very cool.

cool looking stuff

I've done some of these.
The hard part is figuring out his mechanical escapements using springs.

I'd love to see what you've done brian. What "kerfoffles" me is, i understand some of the basic gear movements that are constant but some of his movements are "cyclic" if that makes sense? And you have to figure a trigger/per revolution, if i am explaining it correctly?

This guys stuff is beautiful art and a lot of thought and planning went into it.

Yo Jack you may remember that gear project I finished and posted about a month ago in Show & Tell. I was feeling fairly smug about it until I stumbled across the work of Brett Dickins, a fellow out of Australia that has turned it into a true mechanical art form. I'm guessing he cuts the gears on a CNC or laser, he doesn't say, but check this out and watch the whole thing. The guy's work is amazing:

Back to the drawing board for me! :(

hey mark post the link to your show and tell. I have seen this guys stuff before, it is cool.

I would love to know what Brett uses for a drive motor. I settled on a microwave turntable motor but I don't think that's the best solution. I sent him a message and asked him. Maybe he'll answer. :confused:

I went to your link...now i recall..in comparison i wouldn't be so smug:rolleyes: lol JUST KIDDING that is excellent, better then i could do for sure.:)

I think because maybe my terminology isn't right but yours is like a direct drive circular motion because the gears are all circular and one drives the other, ect.

Do they call it "kinetic" because some of the shapes are not round? In some of this guys sculptures it would seem as if a smaller gear is driving the odd shape on top of it, or am i not seeing it correctly?

I can see how you could adapt "kinectic" shapes onto your sculpture where one larger shape bypasses another because it is offset out further and slides behind it. As i said before your is great and something to be proud of.
But out of curiosity how much time do you have in that project and if you were to sell something like that what would it go for?

It seems to me that you would almost have as much time invested in making one the size of an alarm clock or a large wall hanging and one like your wall hanging is far more impressive.:eek:

Haha Jack, I think Brett's terminology is wrong. The energy is not really kinetic,...it's purely electric and without a drive motor, obviously nothing would happen. What he shows, however, is how complex and really cool things like this can be. To me, it is both challenging and fascinating both from a mathematical and engineering standpoint. I don't know if I have the smarts to figure it all out but I am working on a second effort that while not nearly as complex as some of his works, is a lot more colorful and maybe as much fun? We'll see and I'll post when done with my next effort.

Who would buy them and what would they sell for???

WHO KNOWS? :D

Edit to say: I think the work you posted by David C. Roy is just as fascinating if not more so. It is truly "kinetic".

OMG! http://www.youtube.com/watch?v=tIfnxYlIoVE :eek:

Some of David c Roy's kinetic sculptures will run for 16 hrs on a single wind up.
He's been at it for more than 20 years and was a physics major.
If you go to his site you'll see he started simple and worked his way up to the more complicated ones.

Well whatdayaknow?!? He replied! I had also sent him a link to my gears vid:

Hi Mark,

Great job on your gears, the cut out designs look really spectacular. I get my motors from old VCR's, they control the insertion and ejecting of the tape. They have a worm gear directly off the motor output shaft and a series of spur gears which gears them down to around about 60 to 40 rpm. They have a mechanism which prevents them from rotating a full 360, so you have to take them apart and remove it. Also in most cases you need to remove the gear assembly from the chassis of the VCR with an angle grinder, though on occasion you will find one which just unscrews. Steer clear of ones which have a pulley off the motor to the worm gear (usually found in older VCR's), as the belt will wear out long before anything else will. I run them on about 3 to 7 volts, depending on the speed and torque required, and they always deliver plenty of torque to run anything that I'm building. What motor did you use for the one in your video? It looks like a really good speed. My wooden gears I get laser cut by a local engineering firm.

Thanks for the video, I look forward to seeing future projects, your gears really look great. Hope the above information is helpful.

Cheers,
Brett.

I replied back and told him I used a microwave turntable motor and I think I'll stick with that. Gee, he thinks my gears are "spectacular"! :D
