  1. Hello :) It's been a while since I was finished, but I think it's worth showing here too :) Dressta TD-25M series-1 by Bricksley, on Flickr Scale 1:18, the whole thing is based on new electronics, which is something new for me, although this was not the assumption from the beginning. The model followed me for a long time, the appearance of the yellow 7s sprockets already gave a signal, but only the information about the yellow tracks in 42131 gave hope for a cool look (you know the paint from the tracks is coming off quickly, so the current DBG would do the trick, but;)). Unfortunately, disappointment soon came because the current 5s tracks would be perfect, the 7s are a bit too wide, but as often in real machines, in addition to a few standard track sizes, customer requirements are met (similar to the size and type of equipment), so I turned a blind eye to it. on the scale of these unchanging elements, the result is 1:18 :) As electronics, there were plans to put on PF, which in the case of pneumatics gave me some advantages, unfortunately, since the model was to be used at exhibitions, the IR control is out of the question, and as I prefer everything original, I chose hub from Minstorms Robot Inventor, obviously not perfect, but has some advantages that I gladly took advantage of :) Dressta TD-25M series-1 by Bricksley, on Flickr Dressta TD-25M series-1 by Bricksley, on Flickr As a real machine is equipped with a hydrokinetic drive, it would be reasonable to use a subtractor to drive - it reflects this type of drive and steering, but as the model with free space in the middle does not boast, the choice went to the standard 2x motors (PU L) for the drive, one each to the side (z12 / z20 -> planetary hub), but so that there was no "sloth", the 2 steering drive is simulated by code, so it runs correctly in total, and since the HUB can play sounds, we got a reversing signal and a warning signal (horn) :) Track frames in accordance with the original 3-point mounting (sprockets are rigidly attached to the frame and are not connected to the traction frame), small turntables are used as pivot shaft (track frame), the equalizer bar is oscillating (no pin mounting to the traction frame - in line with the real thing), so that the frame does not have a tendency " walking "sideways, as in reality, slides are built (main frame-traction frames). Consequently, the traction frames hesitate in line with the original, but the weight of the model has done its job and it is not effective - although it is fully consistent with its appearance. The idler wheels themselves are smooth (yes, it is possible), no tensioner - in the early versions it was and even worked, but the required range was small, and the idler (shock absorbers) have high inertia in the initial phase of movement, unfortunately resulted in the removal of this add-on. Dressta TD-25M series-1 by Bricksley, on Flickr Dressta TD-25M series-1 by Bricksley, on Flickr Front & rear attachment - initially I assumed full movements of everything, unfortunately the place, once again the place and the specificity of the ploughshare hydraulics control (in fact most of the movements are connected with each other) meant that there were only 2 basic movements left - but for LEGO needs I think it is sufficient. Hence we have: - lifting / lowering the ripper, manual pitch only, but the pneumatic cylinders have pneumatic hoses ;) - lifting / lowering the blade, no tilt movement (tilting to the side) and pitch (tilting forward - something that in 42131 is incorrectly called tilt;)), Dressta TD-25M series-1 by Bricksley, on Flickr Dressta TD-25M series-1 by Bricksley, on Flickr Dressta TD-25M series-1 by Bricksley, on Flickr As I have daily contact with a real machine, including documentation or the production process, this excess of knowledge was disturbing at some points. It is known that a model made of bricks is not a reduction model, and a man would like to capture many details (preferably all);) Hence I will not say, the details took some time, of course there are those that will be noticed by few man and for most will be the background, no less I do not regret the dedicated them time.

  2. In 8043 & 42042 it work so slow, soo what it will be in set that size? Nothing good.
  3. I confirm. It seems that since the crawler dozer has a simple function, the blade (construction, types, operation) will be as simple, unfortunately the operation is not as obvious as it looks ;) Personally I am dealing with it at the level of R&D (one of the producers) ;)
  4. Or 1 hub, 4 motors: 1+2 drive & 3 for move + 4 for move change. Early people talking about just 1 HUB not 2.
  5. Can You explain what You mean? Lifting is not dependent for tilt & pitch. I'm know, geometry & movement of blade is not simple as e.g excavator/loader but it works :) Someone talk about 4 movement (control+), so there will be: lifting blade, pitch blade, lifting ripper, lifting ladder. Of course it was great to see it, but I'm not sure it will be included in set, not MOC ;)
  6. A big simplification without going into the structure (blade geometry) and the operation of the working hydraulics. We skip lifting (2 cylinders). The tilt movement can only be realized with 1 (left or right) cylinder - the blade is connected to the beams, cylinders and trunions in such a way that the movement of one cylinder causes a kind of blade rotation (tilt). By adding a cylinder on the other side, we get the possibility of another move (pitch). Just pure mechanics (geometry + physics).
  7. This is not tilt blade, it's pitch blade. This kind of blade can has 3 moves: 1. Lifting (up/down) all blade. 2. Tilt: 3. Pitch: In 42131 we've got only lift and pitch.
  8. Hi :) Today I wanna show my first finished alternate model - Racing Truck - B model of 42123 set. Racing Truck - 01 by Bricksley, on Flickr The set 42123 was bought at the end of December 2020 and the alternate model itself was ready on January 2 :D Unfortunately, the premiere was a bit longer ;) The truck is built of 554 bricks and includes the same functions as the model A, i.e. working V8 engine, front steering axle, opening doors. I also tried to show some details. Racing Truck - 02 by Bricksley, on Flickr Racing Truck - 03 by Bricksley, on Flickr Racing Truck - 04 by Bricksley, on Flickr Racing Truck - 05 by Bricksley, on Flickr Racing Truck - 06 by Bricksley, on Flickr Racing Truck - 07 by Bricksley, on Flickr Racing Truck - 08 by Bricksley, on Flickr Racing Truck - 09 by Bricksley, on Flickr The model also has an instruction made by my friend @M_longer Building instruction: Video:
  9. You're right, but only in half ;) When we look at the side, changing color of the rims would look better. However if we look from the front we see inner part of the rim and here the black one would look much worse. So I decided to compromise and I used a yellow color ;) It's old M_longer's idea ;)
  10. Hello everyone :) Today I wanna show You my newest MOC - it's wheel loader Dressta 560E Extra - 1:21 scale. With full PF control and classic MT cover. Real machine: This is my second approach to this model, but that was 10 years ago and hmm ... today there is nothing to brag about;) This time, my main goal was to focus on the appearance and details (stairs, railings, fenders, cabin interior, body elements) hence it took a lot of time during building. In addition to the appearance, we also have a fully remote controlled model based on the elements of the PF system. - drive: PF L, full 4x4 with differentials on each axle, the rear is pendular, additionally working (while driving) cooling fan, - turning: PF L & two small actuators, - raising the arm: PF L, - bucket rotation: PF M, the only motor placed on the front frame - just like the cab, The whole powered from the rechargeable battery box placed in the back - unfortunately it is fully built-up, but left easy access to the switch and charging. Some photos: Video:
  11. It's nice to see that someone has taken up such an interesting topic, I have been preparing myself for some time to the dozer (another manufacturer), but it will be some time;) Knowing how interesting is the geometry of the blades in dozers and how difficult it is to construct real ones ;) I wonder how much you reproduce the movements of the blade: only lifting and tilting or full range: lifting, tilting and pitch? I will be happy to review the progress of work :)
  12. I don't know if somebody noticed but in set we've got 3 pendular axle: first (also steering), third and fourth, only second is fixed. And new shape of blue small pump:
  13. No, we've just visual effect. When we turn cutting head with vertical position to horizontal (by use black 20 tooth gear) saw blade falls - looks as if it was ready for cutting. And I fixed photo in my earlier post ;)
  14. Everything depends on the building model, but certainly we get more new capabilities :) The new valves get easier control and interesting assembly method. And finaly done:
  15. I'm bulding now ;) Parts list: And new valve:
