37,112 times Well I did it. I built a machine to test this. It took 10 days until the LEGO at the bottom couldn't stay on anymore. >>> Check my blog for more details

The optimal clutch power is attained after 8 to 10 couplings(search for "clutch"); that is, before that, the bricks will sometimes cling a little too much on each other. However, I don't think anyone ever actually stated when clutch power would start to deteriorate. I'd tend to assume that once the optimal clutch is reached, there is just enough plastic at ...

I have some standard Red 2 x 4 Bricks that have been stuck together in the same configuration since the early '90s, I just separated one and tested it compared to another Red 2 x 4 Brick from the same era, (and probably the same basic building set), but stored loose, and I could not discern any real difference in clutch power. This is of course highly ...

I'm not sure there's any official answer for this, however I can answer with an anecdote. There have been a few times where I've come across old bricks that have been assembled together for a very long time (ie many years). When prised apart, I've spotted that the studs have actually made an indentation on the sides of the tubes. Based on this, I wonder ...

Each time I've heard someone from LEGO speak about quality, they tend to insist on on simple message: they can't do anything on a problem they don't know about. This may seem very obvious, but they feel it needs to be repeated anyway. What this means is that they want every single customer with any quality problem to actually report it. Apart from the fact ...

This was a common problem with ball sockets in Bionicle figures released between 2007 and 2010. The first wave of Hero Factory figures, which the pictured elements are from, also used this style of socket, as well as regular bricks with ball sockets released during that time. The problem has been addressed by The Lego Group, and the new ball socket elements ...

I once talked with a Lego Builder at the Florida park. He told me they use a glue that actually melts the Lego blocks together. With that in mind, I searched and found this article (on Facebook). It says Lego Park Model Makers use a solvent based plastic weld. It heats the bricks up so the edges bind together. Obviously it has to be very strong to ...

Yes, but not very noticeably or quickly. Keeping bricks assembled will always create stress on the bricks, and will gradually warp the plastic. However, the rate at which clutch power is affected, and to what degree is unclear, and depends on other conditions. My most pronounced experience with this was a set (6085) that I purchased which had likely been ...

Is there a specific scenario in which it should be unbreakable? You definitely should use different techniques to prevent a spaceship from falling apart when dropped from a meter and to prevent a brick wall from separating when hit by a rolling football. For System bricks using larger, longer bricks in overlapping configuration (think real life bricklaying) ...

This is really nearly impossible unless you have a lifetime supply of super glue. A good structure using Technic LEGO bricks will provide better support and a lot more "stick" to each other, making the creation less breakable. Building the structure in which the strongest side will take the most hits/pressure should be an excellent way to make the model ...

In my case, it depends. On older minifigures from the 80's, 90's, and early 2000's it's okay. (I'm not saying it's a good thing) Sure, doing it too many times will gradually wear them down, but not enough to the point where the torso or arms break. New minifigures from 2012 and onwards though, NEVER TAKE THEIR ARMS OUT UNDER ANY CIRCUMSTANCES! Newer ...

Try to keep the track in mint condition. For example, don't expose it to extreme heat or cold. Keep it away from any pets or children who don't know better. Looking at some pictures, it seems that the vehicle on the monorail runs on a gear. Try interchanging gears every so often so that the gears don't wear and the teeth don't get bent or break.

It's hard to answer this question without knowing more about the model in question. Something like a small Lowell Sphere would probably be made 'unbreakable' by a little squirt of expanding foam insulation inside. A Technic vehicle would be a whole different problem.

The track is pretty durable. I have several pieces of old track that the motor runs on well. With the 3D printers now available I am hoping to be able to "print" some of the track with ABS filament. Getting the gear teeth just right will be the tricky part and the end connectors.

Having them connected may actually increase longevity, at least for parts of the brick. This shields out light and air pollution. I have several LEGO bricks that were connected for 30+ years, and the sides exposed to air (and Los Angeles air pollution) were significantly more yellowed than the sides that were connected.

Minifigure hook hands are easily broken — especially the gold-coloured hooks from the 2010 Pirates line, as the material used for gold pieces is rather fragile.

Lego bricks can withstand a fairly high pressure before they deform, but Lego creations tend to deform more easily at the various connection points. Therefore it's possible to build a relatively easily deformed bridge using long pieces, such as technic beams. You could build a bridge that deforms easily and then show how it flexes under the various weights. ...

I have designed some special measuring tooling for my previous employer that uses strain gauges, but is is not always that easy. You need for sure: an amplifier, glue them on the construction in the correct orientation 2 strain gauges on both sides for temperture compesation a way to calibrate the measuring device or construction this resulted for us that ...

98% precent of all the broken LEGO pieces I own are colored in reddish brown. I've broken a lot of them too. Just broke one right now, in fact. They probably use a weaker type plastic on them. I seem to be the only one who's ever noticed this.

The ones that gave me the most trouble were the "new-style" BIONICLE axle connectors like this one: It seems that the parts holding the axle ball were much thinner than on the previous versions, and they tended to crack and break from extensive use. It was possible to use some cracked ones, but some broke beyond that.

I've found that when a hand is pulled out it often (but not always) creates a crack in the arm, so that when the hand (or another different-colored one) is replaced it'll be a bit loose. It could certainly depend on the age of the minifig tho'.

They are not designed to be removed and doing so can make it hard to replace. It is not a very good idea to remove Lego arms except on the minifigures listed above.
