I'd like to see some pictures of the clamp with a large cylinder.

it uses the same, small piston. these are pictures i made some time ago; i'll try to make a couple more tonight with the grabber partly disassembled if the above are not clear enough. Happy bricking :-)

Haha great idea! Imagine a techfig with the body shape of a weightlifter...

I converted the clamp itself to pneumatic operation and transplanted it onto the Unimog. Works okay but the small la gives much more grabbing power. Lots of fun opening and closing it though, as it makes a cool sound when it snaps shut. It reminds me of sea creatures somehow. :-) Will try to make a picture tomorrow; it's a simple enough operation. For the boom and dipper i would use two cylinders each, in serial to extend the range of motion.

I made a few changes to the cabin and digitized the model in LDD, just in case I might want to build it again later. I was goint to attach the LXF to this post, but the maximum attachment size is insufficient. I'll send it by email to anyone who's interested; just send a pm if you are. Part count is around 650 which is much less than I'd thought but thankfully too much to enter the TRIPLE contest as I spend too much time with this hobby as it is already haha.

Hi All, This moc was inspired on 8069, which looks nice enough but doesn't quite cut it as far as playability is concerned. In the end, only the nose section remained more or less the same as the original model; the rest has been redesigned completely. I might have a go at adding the backhoe later but i'm quite pleased with how the back looks so probably won't bother and start a whole new moc instead. Features: - Pneumatic raising/lowering and tipping of the bucket - Manual pneumatic pump - Compressor driven by the back wheels* - HOG Steering with the exhaust pipe at the front - Functional steering wheel in the cabin - Proper techfig seating (*wich works okayish but since the little pumpt can't quite deliver enough pressure for this application it's more of a prrof-of-concept for future use) I have not digitised the model in LDD yet, and have no idea of the piece count, but I estimate it will be around 800. The weight is 664 grams. Maybe a bit over the top for such a utility vehicle but i like shiny things hahah :) Location of the main pump at the right. There's a small ladder on the left side. Location of the compressor, driven by the back wheels via a diff. See you later; happy bricking!

I think it looks awful, sorry.

I am also very interested in this topic. As the layout I am planning will have to be very light, I am trying to find a way to create a tunnel that requires the least amount of lego bricks possible. In my case, the tunnel will not go through a mountain, but underneath a stretch of water. The track will have to slope down at least for a few studs, and the water level will be elevated above the rest of the layout for the rest of the height needed to allow the train to pass underneath. The height difference will be covered by a dyke; typical for the landscape where I live. I have not seen examples of such tunnels made in lego yet, though ...

Marvellous!

Hey Joe :) You'll find some pictures here. Scherm

Thanks! Yes i see what you mean efullner. The shop did get 6 studs more depth for the full width, but i did not add extra roof area. The part with the shop on it still attaches with pins to the platform so it can be aligned in different ways. The main platform has been lengthened with 6 studs since the pictures were taken, but the part across the bridge i want to keep as short as possible.

7937 can do with some improvements, i think. i don't mind the single-track span of the walking bridge though, as i won't be able to lay double tracks in the space i have to work with anyway/.. Taxi has some defined area to pick up and drop off passengers. Streetlights were brought to decent hight. The extra floor area made with the superstructure plate of the engine that comes with set 7939, wich has been dwarfed into a little shunter. Leave that alone, Frank! Happy bricking :-)

Not so much speculation but rather something that I think might make sense to implement (with my limited experience): I whish TLG would add another PF engine block to the portfolio which differs from the current one in two things: mechanically geared down to 150% - 200% of what the current motor's ratio is. Secondly, the half-pin that is used to use the motor in a bogey configuration shoulld be removable. It would also be nice if there would be more studded area for better adhesion of the superstructure.

Thanks for the kind remarks! As far as the design goes; while I was building I kept a picture of a shunter loc from a model railway nearby as a basic guideline, but with the limited number and types of parts in my collection it quickly became clear that the final result would be more of an archetype than something that resembles a real-life locomotive. Also the decisions to house all the PF functions in there; to be able to sit at least one minifig in it, and that the battery box had to be easily removeable were factors that dictated the looks of the model. That and of course my limited skills as a Lego designer of course :)

Hi again, Recently there was an offer on set number 66405 and I could not resist the temptation. Yes the box is huge, which should have been a warning, but only when I had built the engine and the three cars, and laid out all the track on the floor in our living room, I realized that I was in a spot of trouble. See, since we have only little space in our apartment, we'll only be able to have a very small track layout to play with. if it's going to be a (semi)permanent setup, which is what I have in mind. It's not so hard to design interesting small layouts, but running a train the size of 7939 on such a short stretch of mainly bends and switches does not really make sense and is not so enjoyable. The first thing in order then, was to design a small engine that could serve as a shunter loc of some sort. Since it would have to be self-contained with all the PF parts in it, and the amount of system parts in my collection is rather limited, the engine is definitely the biggest challenge to tackle. What follows is an impression of my first shot at making such a small shunter loc. I hope you'll enjoy the pictures. unfortunately, when making the construction to hold the control panel, i broke one of the very old parts in my collection that came from the 857 set (the thing that holds the headlights at an angle) :( The battery box is very easy to take out as it is not attached with studs at all. The cover for the switch is simple but effective :) Happy bricking!

sadly, the page with the technicbricks article is no longer available, or so it seems.

For some time I have been trying to create a pneumatic driven scissor lift small and compact enough to be used as an alternative back module. This morning I decided to let go of the pneumatics idea and converted it into a worm-gear driven mechanism. This time there were no problems to complete the model in LDD, other than it not having available the 9M beam in the correct color (dark grey): The real thing:

A small and simple model compared to all the other models in this thread:

Nice review! Sorry to revive such an old topic, but I thought it would be appropriate to add a link to my modification of this model here, in light of the comments above and the other mod mentioned. Here's a pic:

I forgot to mention that front and back are separate modules; only two axles need to be removed to take the front (or back if you wish) off and replace it with something else.

Since the model is so compact, photos give little more information, so i made some screenshots in LDD instead. The light grey axle joiner with the vertical steering axis going through it needs to be positioned the other way around of course, so the axle can rotate. I only just noticed that mistake in de model :) Here you can see the location where the 2nd bevel gear should go but LDD won't let me place it because it rubs slightly agains the worm gear. I did not find an easy way to put the worm gear one or even 1/2 stud backward without lenghtening the chassis even further, so I left it at that. I hope these are useful! Happy building :)

The real thing: The original is one or two studs shorter I think; I am not sure how much.

Hi again, I just finished recreating my mod of the 8065 mini Dump Truck and would like to share it with you. There's two things missing/different in the lxf than the original moc (not counting the bucket); the bevel gear for the tilting mechanism rubs against the worm gear so LDD did not allow me to put it in the actual place. The black 5l half beam at the top front of the cabin holds two 1x1 clear round plates in reality but as this is an illegal connection I had to leave it out in LDD. Happy building, Sandor

The rubbing is not that bad RockBrick. [edit] you'll need to add a half-bush to each axle to widen the track width slightly though [/edit] I chose these tyres because I like the way it rides/steers much more with this particular model. Especially on very smooth surfices the difference quite noticable. Of course you are quite right that as far as the looks go the balloon tyres are more appropriate than these low profile racing tyres.
