Nice attachments. I am literally in the middle of doing a very similar project! I'm cheating a bit though and using the 8063 tractor. Luckily I have a plan for a different attachment, so no copy catting.

You seem to have gone for a far more sensible scale. You are right - mine is rather huge, but it doesn't flex or bend noticeably when in use, so I'm pretty chuffed. There's plenty of space for the mechanisms. The challenge was in getting the beams and bracing to line up. There's a little bit of distortion, but not much. I will try and find some time to do a video or two. It may have to wait until the weekend though.

Hello, This is my first MOC post that I'd like to share. Inspired by my childhood growing up with my Dad's Meccano (Apologies for the swearing there), I felt this was a subject that's not really been covered in Technic - I didn't find any other creations when researching it, so maybe this is something new! Anyway, here is my attempt at a Giant Block Setting Crane, Meccano's (sorry again) figure head model. It's a bit of a colour vomit, but my funds don't stretch to buying new parts of builds like this. I tried as much as possible to colour code sections. It is IR controlled with 2 XL motors driving the tracks, an L motor each for turning the upper structure and the winch drum, and an M motor for the travelling carriage. Tensing in the carriage cable is adjusted manually using two large LAs. The claw is pinched from the Crawler Crane. It all works pretty well, although the worm/24t gearing for the carriage travel is a bit slow compared to the rest of the functions. I've put a few images in this post. More are on brickshelf: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=566487 Hope you like it. Paul.

Is part of the problem that you are not using an "Official" gear pairing? I find that if the torque is a bit high anything that isn't a standard three hole gear pair tends to skip. The 16/20 tooth gears do go together as you have done, but imperfectly. 12/20 is the perfect match. In the real world, the centre distance of meshing gears are very tightly controlled, for good reason.
