    It appears from the photos that the bucket chain is supported from below and above, to eliminate sag in the bucket chain and thus eliminating loss of material from preventing the buckets to tilt backwards. For the bucket chain I would suggest not using lego tread pieces, but use some technic build solution, it would be more compact and function better/be much stronger. Maybe something using connected 2l or 3l liftarms to form a chain, and drive it with a tire or a sprocket. I think it would be rather fun to build a large scale bucket excavator, like the one posted above, all of those cables would be a fun challenge to work out... maybe some day when I have enough parts I can venture out into some larger tracked vehicles... and wheeled ones too. Also that looks like fun to see something that large in person.

    Well as you can see it is rather easy to form any structure with benzene or cyclohexanes. So I made 2,4,6-trinitrotoluene (TNT) for fun. Now to see if it's possible to make a Buckyball. I think it would be possible with this part. Maybe I will see about building this digitally on Friday... after my Organic chemistry exam.

    I added the tire to it, there appears to still be a small gap, though I think it will work fine. Here's the full engine it is a part of. Lego Chrysler A57 Multibank by Tommy Styrvoky, on Flickr Lego VC Firefly engine by Tommy Styrvoky, on Flickr

    I won't be transferring power through the gears( it's just purely decorative), though I think it would work just fine, though the number of applications for this are rather useful. The biggest issue was centering the middle gear, so it makes contact with all of the teeth on the other gears.

    I was wondering if someone could test this in real life, to see if there are any meshing issues/structural problems.This is the flywheel part of a completed Chrysler A57 Multibank 30 cylinder engine. LDD file http://www.bricksafe.com/files/Tommy_styrvoky/A57 Chrysler Multibank flywheel .lxf The real engine is arranged in 5 L banks of 6 cylinders.

    Unfortunately Lego lacks a part with tetrahedral structure of 109.5° I'm surprised lego hasn't done a molecular model kit. It could include a lot of interesting connectors, maybe they could make a 108° connector for making cyclopentanes and a 60° connector for cyclopropanes and epoxides. Those parts would be rather useful, as for making any sort of rigid geometric axle based shape is nearly impossible if you want to make any odd sided shape.

    Maybe it would be something to request on the bricklink forms, and option to embed the 3D view, as for me to get my model into a form that worked with sketchfab required me to import into Blender and bake the materials from the model to textures. Another suggestion would be to use Mecabricks, as they also utilize a 3D view, though it is only in html format for the viewer. If only Eurobricks allowed HTML and bbcode. Then I could embed this http://www.mecabricks.com/en/models/L0Qa3Zb7vMo [iframe] frameborder="0" height="480" width="640" allowFullScreen webkitallowfullscreen="true" mozallowfullscreen="true" onmousewheel="" src="http://www.mecabricks.com/embed/L0Qa3Zb7vMo">[/iframe]

    [sketchfab]77e8cc4e04734dfdbdcbf2b02b419afe[/sketchfab] Test Brick by Tommy Styrvoky on Sketchfab Must be a plugin problem, though It should work, but eurobricks is missing the sketchfab plugin
  9. Tommy Styrvoky
    Maybe it could be implemented, so a user would have to click on the 3D view to load it, rather than load it when the page loads. I think it would be cool, as I could export any of my models as an .obj file from blender, so it would have a 360° rendered view. I am gonna try uploading something to sketchfab and embed it here, and see if it works.

    Great job, I always think it's fun to 1+ yourself when you rebuild old mocs, I guess this also shows how far new system parts and third party devices have influenced and improved the capabilities of a builder to make things smaller, more compact and highly detailed.

    The Ideal tool for separating parts would be something thin and strong like a feeler gauge, but covered in something soft like ABS or other soft sheath of plastic/rubber material, as the metal core would provide strength but the outer coating would minimize damage to parts. Maybe one of the tools for tearing down electronics, as they are durable, but don't scratch/damage stuff. Potentially something like this would work effectively. https://www.ifixit.com/Store/Tools/iFixit-Opening-Tool/IF145-335-2
  12. Tommy Styrvoky
    I think that's a feeler gauge, I guess it would work well, though with my experience with them, the thinner ones could be bent. That's why I prefer to use a pocket knife in very few cases, such as starting to pry apart a stack of plates, though for most other cases a butterknife works for removing tiles and separating stuff.

  14. Tommy Styrvoky
    Couldn't you just use your fingernail, or a knife blade to pry them apart? As that is what I use when attaching system parts to technic pieces in that method.

    Sadly I have very limited time due to college, and I only have a short one week break away from school during this contest, so I will be working on other projects, as I don't think that is enough time to build a successful MOC. Though speaking of destructive capabilities, I think several of these mounted on the end of a rotating studded beam would be quite destructive if anything made contact with them. I think there is also some potential for creating an interesting drive system for the robot, as I think that would be a good place to score a lot of engineering points, like something with omni-wheels, or a kiwi drive setup. Or another idea somehow manage to create a working flamethrower using pneumatics...

    What about this for a design? I guess you could use headlight stickers for the skylights. http://www.bricksafe.com/files/Tommy_styrvoky/Deck skylights.lxf

    Could one of you update FURY, as it has instructions here. http://www.rebrickable.com/mocs/MOC-6562/TommyStyrvoky/m4a2e8-fury-sherman-tank/
  18. Tommy Styrvoky
    I personally prefer using POV ray in Stud.io, as it allows for live interface with the render viewport. If you want, maybe I Could use cycles to render the completed vessel in an ocean, though one of the minor issues with importing ldd to ldraw, is some part positions will have to be fixed, as the way part data is stored differently based on the models of the parts in each program.
  19. Tommy Styrvoky
    I think it would be rather simple to make one for smaller tracks, just use a 40z gear for counting the gears, then have two 16:8 ratios = 4:1, so every time the 40z gear moves 10 teeth, the output counter moves one full rotation. I think it would be possible to make a combined mechanism for both track sizes, just us a 16z gear for counting the tracks, then have a 16:8 ratio, then the large 8 tooth sprocket, and finally a 16:20 ratio for the output to the counting mechanism. as you would get a 1:1.25 for the large sprockets, and a 2:1 for the smaller chains.
  20. Tommy Styrvoky
    I think it would be possible to connect both outputs to a simple gearbox, then you could either have both axles rotating in one direction, or opposite, to allow for solely linear motion and rotational motion. As unless you plan to use an EV3 or mindstorms motor to control it, there will be differences in rotational speeds in PF motors, and the gearbox fixes that.

    If it sounds too good to be true, then it is. There is probably a high chance those sets were stolen, and they are attempting to get rid of them before they are caught, thus dragging in the individual who "purchased" the sets. As returned/damaged items would be restocked, or returned to the supplier correct? Rather than some sort of sketchy side deals. I would personally rather pay an extra $50 just for the lack of hassle, and a guarantee that all of the parts would be accounted for, for all you know he could have obtained lego boxes, distressed them, and filled them with some sort of 3rd party Chinese knockoff parts, just to make easy money off of some unsuspecting person.

    You can either Use Bluerender if you want to work solely with LDD files, though I use the internal renderer pov ray via Stud.io http://studio.bricklink.com/v2/build/studio.page Or you could use Blender's Cycles animation program, by exporting from studio to Ldraw format, it can be rendered in Blender. This is more for if you want to rig/animate and achieve more realistic lighting via physically based rendering materials, though this setup is for more final product designs, and is more system intensive, though can produce better results. Here's a couple comparisons, though not entirely of the same object, but it just shows the detail of each renderer. Bluerender Lego Porsche GT3 RS macpherson strut suspension by Tommy Styrvoky, on Flickr POV-RAY from Stud.io Lego IS-7 Turret WIP by Tommy Styrvoky, on Flickr Blender's Cycle's render with Ldraw importer and PBR materials with HDRI lightbox Lego IS-7 Turret WIP by Tommy Styrvoky, on Flickr That's going to be massive when completed.

    I think this would work, I don't know if there's a better way to mount the walking beam. http://www.bricksafe.com/files/Tommy_styrvoky/triple expansion steam engineV2.lxf
  24. Tommy Styrvoky
    I found this GIF to be rather helpful, it's basically obtaining maximum efficiency from steam, rather than using a single piston, it uses three. I'm not sure about bricklink for sharing files but I use bricksafe, and that works. Also learned a little bit more about these engines, didn't know the Titanic used a version of these with two low pressure pistons, I guess it makes sense for the time period, though I never really thought about it from an engineering standpoint. is this sort of what you wanted to have attached to the condenser?
  25. Tommy Styrvoky
    Looks good, I'm not sure how structurally strong they will be, though I was sort of lacking the context of the engines, could you provide further information of the lever system that you want to incorporate as my knowledge of steam engines is rather limited. such as an example from a different engine of the same style. How would these pumps operate, would it be a set of linkages connected to the low and mid pressure pistons? could you provide an LDD file, it would make it easier to modify the design, as I believe there is a way to mount a connection off of it from the photos.
