  1. As a young builder over 39 years ago, I built the B model 8859 was built a few times. It was the only idea source that we had. The 8859 tractor had a few options of implements, which were all tried out and really broadened the versatility of the main model. In those days there was no internet, we had limited parts, and for Lego to present the other building options expanded our horizons. We have more options to alternative models now, and generally I build the main model only, afterwhich I dismantle for parts and start my own creations.
  2. A seriously cool recreation of a cult classic. I am well impressed.
  3. This is so nice. It reminds move of the universal sets (8082) years ago when they used only one or two motors to do it all. Great playability.
  4. This is a really nice replica, right down to the function. All proven in the video. Thank you for taking the time to show us this. Well done.
  5. Nice model, with good use of that size of wheel. Will it run straight when you pull it back, or would you have to lock the steering in some way?
  6. Happy Christmas! I present to you my MOC in Technic of the Caterpillar 963. I really enjoyed the build, with features of track tensioners presenting a good building challenge. Due to actuator sizing I was not able to have parallel lift, but the bucket geometry and bucket crowd is very good. The build is scaled to suit the larger track wheels. But it was challenging to leave room for the track width and maintain a good structure. Thankfully all worked out well. Three PF sensors are used over five motors. Drive - 2x XL, with L or M used for boom lift, tilt and ripper. Model is now in the dismantling queue for further projects. Sorry but I don't do instructions. Thanks for looking and I welcome your comments.
  7. This is a really nice build, and the smaller tyres work so well. I will be watching this one.
  8. I hope it all works out well for you. I made one some years ago on a larger scale, but the boom geometry was a bit of a challenge, as well as the offset boom. Maintaining proportionately scaled parts becomes more of a challenge with the smaller model. There are numerous pivot points in the real machine which require maintenance or else the entire boom can exhibit much play, these become a greater challenge in Lego. You have made a good start.
  9. This is a very nice sweeper. Very tidy and compact, although I am guessing that it does not have a tipping bin. Nice use of panels. Well done
  10. This is an interesting challenge. Well done for trying it. Please be aware that air performance pumped to a cylinder from a manual pump closeby is totally different to a pump, manual or motorised and located on the chassis of the truck. Also the weight of the hoses needs to be factored in. It is not normally an issue but at these extremes it will be. 2022 will be a long year, so you have plenty of time to get this model refined:)
  11. I would guess that pins with the bush might be too tight on the sections of conveyer which are only a single link wide. I would say that maintaining a consistent flow of pins is the biggest challenge, as the large wave of pins (most of which are rejected) results in the momentary loss of flow to the sensors. This is a really good project and it is great to see the speed of rotation of the delivery conveyer. Well done!
  12. Nice work on the Windrower rake. A good mix of functionality and looks.
  13. Nice work and they are all nice models. Well done!
  14. As you will most likely be driving the large gear racks at the rear of the machine, your loading on the motors might not be as bad as you fear. They will have a natural reduction at the circumference, compared to driving a gear which is rotated at the centre. However if you try to build a centre into those wheels, then it will be a different challenge. I admire you for doing it. My bravery is normally limited to the parts which i have.
  15. Really nice looking loader. As it is only a hand driven gear train to both the tip and boom lift, I can understand the reasoning behind your choices of gears. However if there was going to be a powered option, then you might have to rethink those. But really clean lines and great use of parts.
