Vacuum Engine Seized Up
bonox replied to LegoLord1880's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
That''s fine - just don't complain when the parts weld themselves together. The only other way to get around it is to make the parts (piston and bore) so loose that you won't have much if any compression at low speed. For what it's worth, the start of this almost exactly parallels your description in the first post of the seizing of two parts at high speed with inadequate lubrication. (gets harder to spin, slows down etc etc) This last longer because it's rolling rather than sliding like the piston in the cylinder but the concept is still the same. -
Vacuum Engine Seized Up

there's a reason all high speed moving parts in this world are lubricated and also why "oil-less" compressors don't last all that long. Lubrication isn't just about making parts slide across one another easily - it's also about removing heat, to either keep the dimensions of the parts in spec or to stop the lubricant itself from disintegrating. For amusement and learning though, hit youtube for "stir friction welding" as that's effectively what you're doing to those poor cylinders. -
General Part Discussion

perhaps it's simpler if you understand that databases don't call out new elements, people call out new elements. One of the things people like is to be able to put sets together. If you have a set that requires a certain printed part, then you need to uniquely identify that part rather than just the underlying part shape/colour without the print. That applies whether you're TLG or a seller on a 3rd party site.- 5,259 replies

if i've got parts, i'll build combination of real and virtual. If I have new ideas and don't have the parts, i'll use the digital model to work out what to buy, but I don't always get it right first time in the virtual. Some of the tools in stud.io are helpful in this regard, for example finding things that have limited support. (attached by one stud for example is a useful tool). When building for real and finding things that need to be changed, remodelling the digital model is called 'red pen markups' in the old terminology and can be a bug bear, but needs to be done if you want to follow later or share.

[MOC] LTM 11200 Mobile Crane
bonox replied to mdemerchant's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
very impressive. The scale is certainly slightly intimidating, but it's really nice to see people tackling the stuff that most people don't with the big cranes - the extended jibs and the Y guy arrrangements. Bravo Sir. -

I get the theory, but the (fake) photo shows a stud too big to do that - it's the diameter of the stop ring, not the stud. And I don't need any fingers to count the places where that would be the only solution- 5,259 replies

more to the point though, what would you use it for? It serves no purpose I can see- 5,259 replies

i'm not sure there are any - they were incorporated into the instructions for sets that included them, so try looking for those. It's essentially make sure the transmitter is assigned the same channel (from 1 to 4) as the receiver you're trying to control, then move the controls. If you want it to keep going, or want graduated speed control, use the train controller.

Land Rover Series II 88 1958
bonox replied to nordes's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
What lovely memories of my '71 IIA. The coloured knobs on the levers triggered thoughts of lots of fun times. Mine were much more faded though. I too would love to invest in your instructions if you choose to make them. Great model; well done!- 20 replies

join a lug, scour second hand ads, put out wanted ads, buy from aftermarket (ebay, bricklink, brickowl) or just plain buy from the factory.
