  1. [HELP] BIG walker legs.

    The klann linkage seems to have more up/down movement compared to jansen, which could lead to excessive power demand. Jansen linkage + lots of legs gives the best stability. Another, more complicated option would be a mechanism where only one leg moves at a given time and the walker stands on the remaining ones. like Star Wars AT-AT (from 0:20):
  2. Wow, the fan has quite an impressive performance! I guess this one: https://www.bricklink.com/v2/catalog/catalogitem.page?P=89509&name=Propeller 1 Blade 14L with Two Pin Holes and Four Axles&category=[Propeller]#T=C&C=1 could be even more efficient.
  3. Nicely done! How it keeps the track tension? Is the track exactly the same length when folded and unfolded?
  4. My mechanical clocks

    Sorry, I don't have instructions and don't really have enough time to make them. However, most of my models are very open-framed, with pretty much everything visible. That said, some escapements really need some trial and error and fine manual adjustments to start working properly. For example, my last big clock is constructed around this escapement: which is super easy to make, with around 20 pieces. The rest is easy - just a long drivetrain with 1:625 ratio, the clock shape is not critical as long as structure is sturdy.

    And now something different, watch escapement with a tourbillon :D
  6. Ropa Maus 5 Sugarbeet Loader

    Waiting for a vide too... unbelievable model worm gears... soo many worm gears...
  7. Wow, that is a really creative idea! Aren't there any issues with lightbulb heat?
  8. My mechanical clocks

    Yet another clock. This time, with heavy, long pendulum, allowing for much better accuracy. Running time is 48 hours - this one is quite power hungry!
  9. 41 km/h... wow, really unbelievable! The 3200 rpm on wheels is a feat on its own - I'm surprised that centrifugal forces are not pulling the tire out of the rim.
  10. My mechanical clocks

    All my previous designs were too sensitive to changes in driving force to make pullback practical. I'll definitely give it a shot with grasshopper.
  11. [MOC] Passenger Airplane (Jetliner)

    I like the sleekness of number 2. BTW great project
  12. Great idea! Choosing the right size for third wheel is interesting problem - as far as I remember, excessive ground pressure on it was one of the major problems of this "tank".
  13. My mechanical clocks

    Another update. This time, a grasshopper escapement has been used to set (probably) a new record of lego clock efficiency.
  14. Mark V Tank

    /\ This. Not sure what is more awesome: the build or the video. "He wanted to be a painter...." . How it compares with real one in terms of offroad performance, for example max slope? I presume the model has much better power/weight ratio?
  15. [TC12] The Unrollable

    Nice idea! Kind of reminds me the playstation game Rollcage.
