That problem had crossed my mind. I think that when you try the finished thing you'll agree that it looks like a shower of candy appearing as if from nowhere in a little drift around his feet rather than an unfortunate accident caused by over indulgence in the festive season. Hopefully.
Hi Mukti, the back pieces are larger than the front to allow for printer error. When you flip you card over and return it to the printer it is difficult to get the alignment 100% accurate so I make the back pieces slightly larger and the overlap stops any white edges appearing on the parts. Rob
OH My GOD! Rob, this is thrilling news! I can't imagine anything much more exciting than a Rob Ives online school! Ack! This could be the shining answer to the ailing educational system! Have remarkable people teach what they know to groups online. So much can be taught through paper engineering. And there's not much that's more engaging than making things with paper as well. Win = win.
Last time I wrote you I mentioned I found a picture of the model I was interested in...I guess the way I posted could suggest I had found the model, it was a misinterpretation, I found just the picture, not the model, I mean, the picture refers the model I'm interested. You have posted a link to a tutorial about this model, I'm not sure it was a ready model to download. So, if you have a link to download the ready model, the model finished, please post it here. Thanks for listening.
Again a nice work one more masterpiece completed! I wonder where do you take so much inspiration to offer us such amazing mechanisms...A genius' matter!
Elmer's Office Glue Stick, Extra Strength Gel is sold in 25 gm. applicator tubes in the U.S.A. Perhaps something similar is available in your country.
Applied to the two surfaces of the ratchet wheels and folding them together it will bond tightly if left overnight weighted down with a book or two. Be sure to avoid applying any close to the tabs and hole for the mounting shaft. [Allow about a 20 mm circle clearance.]
This was used on applicable parts for the "Crank Mechanism" with great satisfaction. There is no excess moisture taking a long time to dry as is the case with pvc liquid glue. Once the gel has dried overnight it is like one piece of double thickness card stock.
Thanks for your gently response. I understand limitation of the system, sorry, just wanna help somehow. By the way, the model I'm looking for is that amazing robot, you explained a tutorial with materials in illustration for us to complete...tuts model paper robot, I think.(or tuts comes from tutorial? ) Anyway, I'm not sure you made it, completely or it was just a chalenging for us, members. Do you know which robot am I talking about? I found it cool, too. This one, yes I found a picture in my PC.
thanks Hugo, I'm afraid there is not much I can do at the moment. The search built in is a part of the Drupal system, extending it is beyond my capabilities however, if you can describe the robot I can probably link to it for you. Human search :-)
I was just trying to figure out a triangular folding paper crank shaft along similar principals. Seeing your four-sided version helps me visualize what I was doing wrong.
Ah ha, it’s the old stalag prisoner of war trick, of losing the soil from the tunnel making, through the trouser legs ;-)
Good show, Rob! I shall, of course, withhold judgement until the final product s revealed.

And where, Rob, are to assume the chocolate candy is coming out of Santa? Perhaps a "Santa" chicken would be appropriate.
I'm working on one at the moment. More news soon.
Thanks, I'm putting the finishing touches on my plans for this, I think it'll be good!

Hey Rob,
I downloaded the agreeable sheep for trial. Why are the back pieces slightly bigger than the front? I am not sure if I am missing something here.
Thanks,
Mukti

Hi Hugo, the model is here

You can download the parts near the top of the tutorial.
Dear Rob,

You are right of course! In my defence, I called the other pawl a pawl in the instructions above :-)
Rob, if you were into cycling, you would know it's called a pawl!

Thanks Regis, what a good idea! Use another ratchet to stop the wheel rotating the wrong way. I'll have a go and post the results later on.
Hello Rob !
great project as usual...
I think that if you add a tab at the base, it would be able to prevent a backward rotation
of the Ratchet wheel (I've made a drawing).
Saving the coin of the friction loop :)

Thanks guys! I'll have a look for the Elmers office glue when I'm in town tomorrow and will report back the results.
Dear Rob,
Congratulations!

I haven't done the animation for this page yet :-)
Other animations load just fine but the animation for this example does not load.
In the text it says "...free to download mono version. Click on the Add to Cart button..." but I can not find an Add to Cart button to click.

Thanks for your site, and all of your hard work.

Thanks for the info, I'm having a go at creating some more flash animations to show the different quick return mechanisms and how they work.
