Small Autovalve

This absolutely solves a problem I have with a MOC right now -
Yeah, so this thread digresses into wishes in the way the rumours thread always digresses, but anyway... ...every 3-5 year old boy I know at the moment (quite a few, my kids are this age) has a car ferry, either the playmobil one, or some plastic thing sized for matchbox/hotwheels sized cars. Just saying... Also bin trucks (dustcarts), but Lego City has done pretty well at those

Review: 60022 Cargo Terminal (lots of images)
andythenorth replied to LukefromNJ's topic in LEGO Town
My kids love this set -
8110 is pretty much unplayable. The build is long and boring, there's nothing neat or clever in the functionality, and the resulting toy is pretty poor - heavy steering, poor crane control, too big, too heavy, limited functions. My kids prefer the pull-back motor racers, or the helicopters, or the 8285 tow truck...or 8070 car, or pretty much anything compared to 8110. We have a cupboard full of recent technic sets, most of which will stay intact. 8110 might get stripped for parts.

Solenoid?

The 8459 Loader is insanely playable. 2 year olds love it. The 2013 Monster Truck (42005) is also insanely playable. My kids (20 months, 3 years) take it in turns throwing it down the slide we have in the garden, and bouncing it on stuff.

Playability > everything else

That one was an orange / grey utility truck, there is a better picture 'somewhere' on this forum. Don't know where :) My guess is that was an alternative version of the 'great vehicles' 6-wheel orange / grey dump truck. It's a truck for street maintenance rather than logging. :)

I supported the xs motor project on cuusoo

Rounded end out - looks better innit.

So not really Technic (more Model Team / Creator?) but a very nice MOC

I think I mis-remembered the planetary; I think it was actually a worm drive with 90' between input and output. http://www.bricklink...gItem.asp?P=768 It's more than 20 years ago, but I was sure that education motor sets had a reduction gear with same angle input / output. Bad memory I guess. Worm cage part is this http://www.bricklink...D=136&catType=P Building a worm cage can be achieved with regular parts. Building a compact worm cage that doesn't come apart under torque loading is hard. Worm drives generate high torque, both when rotating, and if they are prone to a shock load when stopping (e.g. moving steering arms, extending a crane arm etc). There is yet another worm drive as a preassembled gearbox: http://www.bricklink.com/catalogItem.asp?P=46220 marginally less flexible in mounting options (studs only). This gearbox shipped in a set that also included a couple of 90' 1:1 gearboxes http://www.bricklink....asp?P=46217c01 I think it's probably nylon, but not sure.

Eh? There is no way a compact planetary mechanism could be built from standard technic gear parts. No planetary = no RC bulldozer, no rock crawler, no excavator, no...the list goes on. So Lego have traded playable functions against trying to teach the detail of how the gear train works. I have no problems with that. When I was a kid, building gear trains got boring fast: "yeah ratios, ok I get it now, I can do maths, but I'm trying to build a racing car / dump truck / lift / lock gate / turntable / bulldozer, and these ABS gears are too big / too weak / too high friction to make decent gear trains". Separate planetary part - that is an interesting idea. These existed for 4.5v / 9v motors and were useful. They could be stacked inline too for more reduction. More recently there was a cage part for making a strong compact worm gear drive - it's useful.

Which are the more complex 80s / early 90s sets? I was an archetype of the 'Hey!' kid back then, but my memory isn't so good now :) For example, here is 1989... http://www.brickset.com/browse/themes/?theme=Town&year=1989

Except in Nepal http://en.wikipedia.org/wiki/Third_gender#Nepal I have not read the rest of the argument in this thread, so have no idea what ideological / semantic debating points you're having such fun with. Enjoy yourselves

Cusoo for new TLG tyres?
-
My 3-and-half year old boy wants the Friends boat. It has Dolphins. "TLG should / shouldn't reinforce gender stereotypes" is a nice first world problem to have eh?
-
That blue would be really nice for a police theme in Friends.

What a totally ridiculous attitude. AFOLS are dedicated serious collectors. If they can't form a knee-jerk opinion on the basis of almost no evidence, then really, who can? I think you need to reconsider if you are a true fan. Your reasonable attitude makes me think that you are nothing other than an apologist for TLG, and possibly even someone they have planted here to cover up the fact that they are destroying everything that made TLG great, and ignoring the valued opinions of many millions of AFOLs. Of course City is dying. It always has been.

Apart from it looks good (it does) - what advantage do you get from moving the shocks inboard? You could just mount them to the bottom arm-with-towball...?
-
Get the hubs on Bricklink? Buying the F1 car is an expensive way to get them (It is a good set though).
-
Even though not Lego, the tyres are badass

If I was setting out to build a fast hill climb buggy, I would probably use: - long rear trailing arms, one per axle, on soft springs. - two PF XL motors - one per rear wheel, mounted inboard in the centre of the chassis, so they are sprung weight; or use the buggy motor - a gear train of 12 and 20 tooth gears along each trailing arm. The friction of these will suck up power, but they will be robust. - front suspension: I would use a live axle sprung on trailing arms - one PF XL motor, or the buggy motor - no diff (assume the ground is rough and the wheels can slip = no diff needed, also hill climbing mostly straight?) - use these steering components http://www.bricklink...tem.asp?P=11949 - use double steering links on each side to reduce the chance of popping them off when hitting bumps. This is conjecture, I've never tried to make anything that goes quick

I have a couple of projects using PF XL motors which have no suspension between motor and wheels. It's hard to build a strong compact vehicle with both a reliable drivetrain and suspension. For steering axles, it's even harder. Of course, there are a lot of trial truck MOCs that have done all of this successfully, but they sometimes look bulky, and heavily engineered. The pictures attached are the rear drive for an 8x8 truck. There is walking-beam suspension between this double-drive axle unit and the chassis, but no suspension within the axle unit. The axle unit is designed quite carefully. All gears are meshed with liftarms, and there is no way for them to slip unless they actually break. The gears are also easy to replace The unit won't twist due to traction torque, but has some flex laterally, so will twist a small amount to follow uneven ground. Diff locks are essential (inspired by Sariel). I'm working on another 8x8 truck which is articulated. This will have no suspension at all for the axles, but will have 3 degrees of movement in the chassis. It will use Power Puller wheels which also have a lot of flex in the tyre wall.
