Gear creating software

Chris,
Is Arduino close to Tatuwin? lol
Electronics is not my forte, soldering circuits and wires is not my thing. Now if i can buy it made up that's a different story.

I have had many splendid experiences with Sculpt Nouveau... and stunning failures! Working with it is 33% art, 33% science, and 33% luck. Each and every time you use it is a new day, and anything you thought you learned yesterday is worthless... There are so many variables that effect the outcome that there is always one or more that are not able to be controlled. Time, temperature, humidity, altitude, attitude, are just a few of the identifiable ones. In the end is it worth it? OH YES! Each and every project is unique and not repeatable... Never tell a customer "It'll look like this" because you just became a liar! Just a word of caution... Using Sculpt Nouveau is addictive.

If you use a Sculpt Nouveau finish your stacked gears will need to be spaced so that they don't rub on each other... then again, there are no rules in this game!

Steve,

I've found another way to do a "rusted" finish that may be easier, less expensive and more predictable:

Scroll down the page and you'll see the person even did a set of gears with this method.

But I still wanna try the Sculpt Noveau and I think using patinas can really make for great looking and truly unique displays. You reckon it'll do good on PVC?

Gentlemen, I've decided that the theme for my next effort will be "Tempus Fugit". Any guesses what that means? Stay tuned!

Tempus fugit is a Latin expression meaning "time flees"

You googled it, didn't ya Jack? lol Best known in English as "Time Flies".

I'm working on a design for a crazy clock display that makes no sense, tells no time, but will be a hoot to view in motion if I can solve an engineering problem I've already encountered. I know there's a solution but I haven't figured it out yet and that's half the fun. Some of this stuff can tickle your puzzler!

Here's the first gears I cut with Ryan's gadget. It's a planetary gear drive designed with a formula I found online... R=(2xP)+S where R = the number of teeth in the ring gear, P = the number of teeth in the Planet gears, and S = the number of teeth in the Sun gear. My setup is R=33, P=12, and S=9. thus 33=(2x12)+9. Since I chose variables all divisible by three, I can have three planet gears equilaterally spaced around the sun. Other variables could result in planet gears not equally spaced or where another quantity of them may be appropriate, such as four planet gears...

I didn't find any tutorials on designing the internal gear, so I just trimmed a regular gear internally close to the pitch circle. It seems to work, but I'm open to suggestions as to the "correct" method of doing this.

I cut these gears just as the gadget designed them...They made a very snug and likely correct fit, but perhaps a little to tight for this project. I'll cut a new sun gear with a few thousandths of allowance.

Overall, I'm pleased with the results, and the planetary gear transmission is fun to play with and see what different combinations of gear reduction and multiplication you can come up with.

Steve,
Have you see this: http://woodgears.ca/reader/walters/planetary.html
it is similar and you might get some ideas or help in your equations?

No I didn't google it, i watch Jeopardy regularly, you'd be surprised at what you pick up from that..plus I always have a back up.....Marina at HotForWords.com

Very cool, Steve. You are now a certified "Gear Head"!

Jack, I think the link you've posted to Ronald Walter's work was initial work for this project here: http://www.youtube.com/watch?v=QzIG9stFXSI

Pointless, useless,...and absolutely brilliant!

What i'm amazed at is, not only the design but the tenacity to stick with it and create something like this. I don't know how long it took him to do this but its amazing.

[tuck]

It is amazing, but certainly not his first go at it. He started somewhere with a learning curve like we all do. But yes,... his tenacity, inventiveness, imagination, skill and craftsmanship are something to behold! And for all I've been able to deduct, he cuts all of his parts with hand tools!

I solved my engineering problem for "Tempus Fugit", I think, and can't wait to start cutting, but I don't have the funds for materials at the moment. Things are pretty skinny around here and I don't have enough scrap laying around to do the job, so it's gonna have to wait but that's ok. I can still design and plan this project, and time spent doing that always pays off. What I've learned in the past week about dowel rod, roller bearings and the right motor alone has unleashed all kinds of possibilities for a whacky, fun kinetic wall sculpture/display!
