  1. Hello Everyone – I wanted to share my first MOC in well, several years. Our beloved Grove GMK6400 crane scaled on the 62.4 mm tire has been an AFOL favorite for years. I think it is actually one of the largest group-sharing projects we have had on here. 42108 inspired me to do a similar one, just at a smaller scale and without electronics. Using 49.5 tires for scale, the below is what I came up with. There is some inspiration from 42108, to be sure, but so heavily modified that it really is no longer recognized as such. Also, it is kinda a motley of others’ creations as well. The outriggers are taken from @M_longer modifications of the set, and a big kudos to him for such a genius solution to fix 42108’s abysmal ones. Also, as is easily recognized, the boom is a modified version of our fan-favorite Grove GMK6400 at the larger scale. One of my sources of inspiration was a comment I made a while ago on that thread stating that as beautiful as the model is, I think the boom is undersized. By my calculations, and looking directly at the blueprints of the real crane, it easily could be increased to 8 studs instead of 6. @mkbryant assisted with my comments and calculated the following: So, with this in mind I kept the same dimension of the larger version (with undersized boom) and applied to a smaller carrier (at tire size 49.5 instead of 62.4) just slightly shorter. I think this given the proportions of the crane greater accuracy than our current Grove version at the larger scale. Boom is 7 studs high and the cab is 10, giving the boom 70% of the height of the cab, which is much closer to the real thing. Functions in the crane are all the obvious, all steered axles, outriggers deployment and raising/lowering carrier, boom raising/lowering, extending/retracting, hook lower/raise, but I also added superstructure rotation, superstructure cab lifting/lowering, carrier side-mirrors with two way movement, and lifting vent in cab (superstructure). Also, all are manual. No electronics. Difficult to throw in electronics, motors, etc. at this scale. I like the manual functions, although they are tedious, especially for raising/lowering, extending/retracting boom. Carrier only: I won't bog the thread down with any more pics. I have a few more on my flickr page. But here is a youtube video showing it and its functions. Comments are all welcome. This was one of the funner (sp?) projects I have been involved in, I thoroughly enjoyed it.
  2. Hi guys, here is my first alternate model of 42078 - Mobile crane. Functions are in video. Here is the video: https://www.youtube.com/watch?v=9HRgx2qHyS0&feature=youtu.be More photos here: https://www.flickr.com/photos/142407982@N08/albums/72157697465100061
