D3K Posted November 5, 2012 Posted November 5, 2012 That is very cool! Not only is it something unique, it also looks terrific! Bravo! Quote
hrontos Posted November 5, 2012 Posted November 5, 2012 (edited) This tractor is really nice. I had few oportunities to see such in real life. I like how it "shakes" just like real one with the same engine. And even the forward movement is not so smooth with this engine - originals with similar engines have the same problem until they reach a certain speed. Very realistic engine and tractor.

nico71 Posted November 18, 2012 Author Posted November 18, 2012 And for those who asked for a video about the engine, I have made on with SR3D to show how it is made. Quote
dhc6twinotter Posted November 18, 2012 Posted November 18, 2012 That tractor is uber cool. You come up with some fantastic creations! Quote
aeh5040 Posted November 26, 2012 Posted November 26, 2012 (edited) Both the loom and the Digicomp I are absolutely fantastic! Awesome work! The Digicomp was actually on my long-term list of things to make, but you beat me to it! :) Many thanks also for making instructions. I'll definitely be making one of these...

nico71 Posted December 2, 2012 Author Posted December 2, 2012 The instructions and the article are available on my website ! http://www.nico71.fr/hot-bulb-pneumatic-tractor/ The bill of material, waiting the aproval for my moc on rebrickable. Have a nice build :) Quote
DLuders Posted December 2, 2012 Posted December 2, 2012 Wow, that's a nice Lego Technic Pneumatic Lanz Tractor! Your PDF Building Instructions are very well done. Thanks for sharing! Quote
jorgeopesi Posted December 2, 2012 Posted December 2, 2012 Thanks Nico you teach us a lot of with your MOCs, I think I will build it, I want to know more about pneumatic systems, thank you again. Quote
Paul202 Posted December 2, 2012 Posted December 2, 2012 Awesome creation, really makes me wish I had some pneumatics. Quote
nico71 Posted January 3, 2013 Author Posted January 3, 2013 Here is some news ! I have finished the project of the Stage Trailer and I will deliver the creations to the customer. You can follow the story of that creation here : http://www.nico71.fr...-stage-trailer/ The video of the model : After 4 month of work, I am quite satisfied of the result and my customer too, it adds a sucess to my industrial references.

lukeandahalf Posted January 3, 2013 Posted January 3, 2013 One of the first models I built was one of your Unimogs, and I continue to be inspired. Great work on the tractor, I will surely build in the future. And the stage is lovely, I've seen many live shows on the north american equivalent! Quote
nico71 Posted January 16, 2013 Author Posted January 16, 2013 If you likes maths, here are some : Very simple and very clever I think, the planimeters are awesome object ! I plan to build some other, include polar and orthogonal for the exhibitions at fanabriques in june, 2013. Quote
captainmib Posted January 16, 2013 Posted January 16, 2013 Wow, that is crazy! Simple yet technical... What's the secret underneath the circle? Quote
Blakbird Posted January 16, 2013 Posted January 16, 2013 If you likes maths, here are some : You make the coolest stuff. Quote
legomuppet9 Posted January 16, 2013 Posted January 16, 2013 This is awesome, are you going to make instructions? Quote
nico71 Posted January 16, 2013 Author Posted January 16, 2013 (edited) What's the secret underneath the circle? Nothing ! Juste a 40/8 gearing. The aim is only math : the green's theorem : http://en.wikipedia....Green's_theorem The trick is that the angle between the begining and the final position is arround equal to the double integral because the cursor follow a tractrix which is arround equal to the derivative underneath the curve, and the double integral is the surface thanks to green's theorem. Some readings : http://www.planimete...et/hatchet.html http://persweb.wabas...Prytz/Prytz.htm http://persweb.wabas...z/PrytzArea.htm ps : yes I will make instructions, it is very basic.

timslegos Posted January 16, 2013 Posted January 16, 2013 You always build the most technical creations, super impressed with this one. tim Quote
Paul Boratko Posted January 16, 2013 Posted January 16, 2013 Really Cool..! I worked with one of these when I was in Drafting Class in highschool.... Quote
hrontos Posted January 16, 2013 Posted January 16, 2013 This is great. I like how you use LEGO Technic to attract attention of people to things they would normaly find not so attractive. Quote
legomuppet9 Posted January 16, 2013 Posted January 16, 2013 (edited) Will you include the template for the dial in those instructions? Edited January 16, 2013 by legomuppet9 Quote
CisFran Posted January 16, 2013 Posted January 16, 2013 your creations are truly mind boggling! keep up the good work! Quote
