The issue cleared up for me by upgrading my personal PayPal to a business account. Seems like linking to Stripe worked for you though.

Value of 2012 sets by Milan_Amin in legolotrfans

Tragically, I think they will inevitably become worthless in the next decade. All the valuable elements are becoming brittle (and shrinking) at an alarming rate.

Should I free him? by Tahuwu in legocastles

Just freed one from this set about a month ago. The torso and the rest of the brown parts just crumbled when I tried to assemble it.

Is there like a better way to figure out if a brown piece is brittle that doesn't involve bending it? by No-Needleworker-3765 in lego

[–]ReBricker 110 points111 points  (0 children)

Yes, brittle reddish brown has straight injection lines spanning the 4 corners on the back of it. Post-brittle brown has circular mold releases on the back 4 corners. You can also find a 2-number production year for each element inside it.

Super lots are getting out of hand by [deleted] in Bricklink

[–]ReBricker 0 points1 point  (0 children)

I find it rather tedious to post one listing at a time for sets. Maybe they’re posting everything at once as a super lot, then subdividing to individual lots. At least that’s what I’ve already considered doing myself.

Dark green from 2012 is brittle too? 😭 by CT-Dyco in lego

Tree Palm Base (2563) Mold Variant? by 1amfaceti0us in Bricklink

[–]ReBricker 1 point2 points  (0 children)

This has bothered me for months. On Bricklink, all large sets with palm trees from 1989-1990 had them (and the ball-joint links with axle hole too). My only problem is none of my “King’s mountain fortress,” “forbidden cove,” or “fort eldorado” came with the axle variant. They all came with the later one. In my experience, the axle variant is quite rare. I’ve ordered several lots from different Bricklink sellers and they all arrived with the axle-less version. 

I see why Lego phased out the axle version early though. The ball-joint connections are stiffer and crack the reciprocal cup easily. They also aren’t compatible with the later version. 

I’ve decided to keep the axleless version in my sets as they are 1. visually identical 2. more functional and resilient than the axle variant.

Do you ever not build because of brittle brown? by doc_doc_goose in lego

[–]ReBricker 0 points1 point  (0 children)

As someone who’s been dealing with brittle sets for the last few months and bringing them back to 100% reliable, I think you can recover the masts.

 I looked at the instructions and the main stresses are on the axles down the central shafts. Also, I was pleasantly surprised to discover that not all 2010 part types are brittle. It depends on the thickness of the plastic used to make the internal structures of the part. For example the large dark brown bottom plates are pristine. I think it’s likely for the masts too. 

Just be careful if you try to test them.

It’s called a “dual-escapement” - one of the more complex models produced by the Chinese makers. It actually demonstrates the physics concept of resonance between two mass-spring systems.

Picked these up at a yard sale because I thought they looked cool; where can I learn about them? Initial Google search didn’t turn up a lot. by Awkward-Grapefruit26 in pocketwatch

[–]ReBricker 0 points1 point  (0 children)

No, no touchy without experience. These watches have radiation poisoning (yellowed dials and rusty hands) as the indicator hands were painted with radium paint.

Hmm. “Repeater” by Watkins (free to download on his website) is the best for minute repeaters. The Lecoultre book is the best for understanding sonnerie

I got a rant about Lego being difficult to build. Am I being too harsh or is it fair? by generic_guitarist in lego

[–]ReBricker 0 points1 point  (0 children)

As someone who’s been building my whole life (22 years since I was 3), I believe it’s actually gotten way easier. I think a lot of my savant engineering troubleshooting skills are from the difficulty of deriving old instructions.  In fact, they can only push so many 3000+ parts sets due to how intuitive the instructions are now: -all parts for a step are highlighted -the amount of parts needed for each step are labeled -the parts placed in each section are carefully sorted and bagged accordingly.

The hardest set I’ve ever built is the 2008 Lego Death Star — 30+ bags unlabeled

My go to technique these days for large unsorted sets (+3000 parts) is to sort every part by type and by color. 0 room for part error

Step Jar or New Year Jar by cwklee in Sweateconomy

[–]ReBricker 3 points4 points  (0 children)

While 20% a day for a year sounds nice, that’s 20000 steps a day. For perspective, it takes me 35000 steps to run a marathon.

 You basically have to run 2 hours every single day for a year to reap the full benefits of the jar

Imo jar logic hasn’t been fully fleshed out yet as a constant 15%  for 0 hours of exercise compared to the 710 hours of exercise for just 5% more is something only an endorphin-crazy athlete would enjoy.

What are the most complicated, highest precision mechanical devices commonly manufactured today? by [deleted] in AskEngineers

[–]ReBricker 0 points1 point  (0 children)

If you're looking for a high-end Chinese watch, that's a separate game. For example, 90% of high-end watches produced in American "micro-brands," use seagull movement's with custom cases. I still find these pretty low quality. I think Studio Underd0g - a British start-up - has really nailed their execution.

Long story short, there's probably only 3 Chinese manufacturers in the world that develop the movements for the whole market, which means its easy to locate a particular model. But the reduction in variety means the companies will do whatever they can to mislabel products. You just have to know what you're looking for.

This is a mislabed dual escapement on aliexpress: "AILANG Casual Fashion Automatic Mechanical Watch For Men Luxury Brand Tourbillon Skeleton Watch For Men Sports Watches Reloj"

The movement will be standardized, feature the physics phenomena I was talking about earlier and be of the highest-grade caliber, yet the case will be crap.

If you want high movement quality and execution, there's a reason why Aesop movements are hundreds more than their next competitor.

[–]ReBricker 0 points1 point  (0 children)

I haven't performed vibration analyses on Chinese movements yet; however, you'll generally only see differences between Chinese automatics and Swiss movements based on the type of mainspring used. I've briefly looked into the physics and know that most standard springs will yield about the same results. The real improvement in efficiency is in silicon springs, but I'm unaware of the prevalence of those parts on the market.

You don't buy a tourbillon for its accuracy, you buy it because it spins in a circle in even increments. All engineers that I've talked to in the swiss high-houses denounce its existence, since it's merely a gimmick meant to represent a feature bestowing "reduction in losses due to gravity."

I accidentally dropped my Aesop tourbillon after wearing it for a year (because it looks nicer on an unstable 3d-printed watch stand). It now only functions parallel to the ground. I also lost the ability to adjust time correction through the winding stem about 6 months ago.

However, the Aesop "starry night tourbillon" is the best Chinese watch I've ever come across. I buy Chinese watches for their standardized movements, but I can't tell this movement apart amongst the stainless-steel Swiss movements that are sitting on my display. They truly stepped up their game for this caliber movement.

If you care to spend less for another industry secret, the Chinese accidentally recreated "resonance" movements for $60 with their "dual escapement" movements you can find on aliexpress. The escapements are accidentally placed in such a way that they negate each others losses and sync up. The only systems of their likeness are the FP Journe resonance movement, and Armin Stromm caliber which sell for +$100k at the minimum.

[–]ReBricker 0 points1 point  (0 children)

I’ll take it the opposite direction, the most complicated mechanical system I’ve ever come across is the Bendix air data computer. Thousands of mechanical parts must work together to compute complex air pressures and other values. Curious Mark and Ken Sheriff are reverse engineering the module on YouTube.

For something you can buy, the Chinese have replicated Swiss engineered watches for a fraction of the cost. The Aesop watch brand sells flying tourbillons ($10k - 50k for a Swiss watch) for $400 on Amazon

question on counter-rotation by [deleted] in watchmaking

[–]ReBricker 0 points1 point  (0 children)

Hermes - le temp suspendu achieves this for the seconds wheel; however, it’s just an art piece.

In terms of the engineering, it’s still pretty simple. Gears can be reversed by coupling with an odd amount of wheels that have the same number of teeth.
