comment Are there LEGO compatible CAD Files For Injection Mold Manufacturing?
Short answer: no. Look at SBrick on kickstarter, for example, who are currently jiggling dimensions to get molded parts to fit with Lego pieces. There's lots of "a few microns off and try again" going on. Or hit shapeways and see all the lego-compatible parts there, maybe even throw your designs on and get some printed to see.

comment Why aren't alternate configurations on the back of modern boxes?
Almost all the Technic sets still have instructions for a second model (online rather than printed). I suspect the problem is that sets and parts have become more specific so it's harder to make a decent B model, especially with the smaller sets. 100 parts, half of which are minifigs, just doesn't give a set designer many options.

comment Can anyone identify this strangely shaped piece (1970s?)
Sadly those rough spots are where plastic pins used to stick out but they're been broken off your parts. Those were part of the support/tipping mechanism on the train model.

comment Looking for a Basic Lego set with mostly large bricks
isn't this exactly what the question was trying to avoid - most of the bricks in that set are 2x2 or smaller

comment How can I tell which LEGO minifigure I found?
@JustinCase to some people the point of Lego is that you can mix and match the pieces, and that's how they use it. Not everyone just buys it, assembles it according to the instructions, then displays it.

comment Identifying Lego kits from unopened bags for library
I suspect that the intention is that the exact sets don't matter, and they may even vary between kits. Because those pieces are going to end up really mixed very quickly, so either you're going to spend a lot of time policing and sorting, or you'll end up with one big pile of pieces. Personally I would resign myself to that now and move on...

comment How many ways can six 8-peg lego blocks of six different colors be combined?
@Bonifer people connect simultaneously in much simpler ways than Lego bricks (Sam knows Bob or not) and in much more complex ways (Sam has heard that Bob is not very nice, but from someone Sam thinks is unreliable). There's not a good match to the Lego "one stud to the left" relationship modelling.

comment Strain Gauge on Lego Bridge
A pure mechanical strain gauge seems more in the spirit of Lego. And more likely to work and be robust. I suspect you could make a simple "spring balance" type gauge quite easily using a rack piece and an 8T gear, with either rubber bands or suspension print parts. Add a cardboard circle as backing and "calibration" just consists of adding weights and marking points on the dial.

comment How can I use 1 motor for grabbing/lifting and another for moving?
Typical solutions involve staggering functions, so at the limit of one motions travel the other motion starts. For example, combine lifting with gripping by making the lift happen when the grip stalls (many older crane grabs work this way)

comment Why are Lego products so expensive in Europe?
I'm going to guess that part of it is that the 19% sales tax is included in the EU but in the US sales taxes are normally applied only when you purchase (partly because they vary depending on your location). So a US purchaser might find state, county and city taxes applied.

comment Design of record-breaking builds
Actually, the 3.5km limit is easily reachable just by making the pyramid wider. If the base was 3.5km on a side and tapered straight to a point at 3.5km high it'd be pretty stable. And heavy. And use a lot of Lego.

Couldn't find the axles easily, this one will have to wait until I unpack the collection (after we move, hopefully in not too many months time)

comment Design of record-breaking builds
yeah, GWR are quite specific and rule out basically anything using Lego Technic parts. Technic cranes often top 4m using truss frames of liftarms, but GWR doesn't allow that either (even if you use "technic brick with holes"). It's stacked bricks or nothing.

comment Design of record-breaking builds
@JoshDM you mean BURPs? I was thinking either 32 long axles or the unfortunately rare 2635 crane leg parts because they're tall and pyramidal already.

comment Any way to make this setup “tighter”?
one reason for my answer was to drop a bunch of those terms in so you can search for solutions more effectively :)

comment Why are official LEGO PDF instruction books such poor quality?
I'm going to guess a combination of poor-quality inputs (a common complaint about printed booklets is black/dark grey/light grey confusion), and a poor process for turning print artwork into PDFs (I suspect they use the default settings instead of forcing PNG/GIF instead of JPEG). Really they should use cbr format direct from CAD instead since that's actually designed for pages of line art.

comment Any good alternatives to BrickLink?
I'm amused that your response to "bricklink is hard to use" is a flat contradiction.
