LEGO Finds - 2015 Week 47

Quite the haul this week. A massive amount of DUPLO, mostly from sets 10538, some 4665 plus a working siren! Also some liftarms, an older style finger puppet and a crayon someone molded from the minifigure ice cube tray.


LEGO Techniques - Pretty Ballsy

The beauty of LEGO is that there is a little bit of tolerance and flex in pieces.  The other beauty is that everything works with everything.  EVERYTHING!  So it should be no surprise that a Hero Factory torso can be the basis for an otherwise completely system build.  Sure, you could pull in pieces like modified bricks with balls or cups.  But then there would be no blog post for me to write.

The balls on the Hero Factory joints are listed by LEGO as being 10.2mm in diameter.  There's not much going on here for being within system.  You can subtract either 3.2mm, 4mm, 6.4mm, 8mm or 9.6mm and never get a result that is within our 0.8mm expectations.  The closest dimension is 10.4 and maybe that's where they intended to land, then cut the tolerance by the 1mm on each side.  This would be two plates of height (6.4mm) plus half a brick width (4mm).  Or a brick height (9.6mm) plus a quarter plate height (0.8mm) Whatever.

But the thing about spheres is that a ring can be placed over it at some point.  Place two rings on opposing sides and the distance between the rings will be less than the sphere diameter.  Lost yet?  Perhaps an example:

Imagine the bottom of two plates.  The 4.85mm anti-studs will slip over the ball joint and reduce the total distance.  What is the distance between these plates (assuming they are parallel)?  A little SketchUp render tells me it is just under 9.0mm which is a little more than a brick width (8.0mm).  But remember the tolerance and flex that I opened up with?


And since the spacer is a typical brick width, it works for other parts with holey relief too, like technic liftarms and bricks.

By the way, these are all the Hero Factory type pieces that I own.  See why the need for more system connections?



LEGO Finds - Calendar Week 43

One little piece this week.  Well, not completely true.  There was a LEGO DC Comics magazine #2 but it was creased and wrinkled and not worth picking up.  At least this thing is functional.  Now I just need to figure out how to use it.  Dark Purple?


LEGO Finds - Calendar Week 26

Congratulations to Mrs. DagsBricks for finding this little piece down in an endless pile of stuff.  Even if she thought it was K'nex. :-)


LEGO Finds - Calendar Week 19

This week was all about ups and downs.  I had found an amazing raised baseplate in perfect condition.  I stuck it in my box and rooted through some other bins.  I came back to find that someone had yoinked it from my box!  Gar!  Very disappointing.  At least I ended up with a Taun-taun.  And some tires, VERY used bricks, technic links and some Chima cards.


LEGO Techniques - Bent out of Shape

As with most any thin piece of rigid plastic, bending can happen.  The thinner the piece, the tighter the bend before it stresses.  So it should come as no surprise that a bar or axle will bend more than, say, a 2x10 brick.  But plastic also has memory.  In other words, make that face for too long and it will stick.

I got a wild imaginative hair with the Ninjago spinner arena that I found a couple of weeks ago.  What if I turned a couple of the 45° Technic axle connectors on this big floppy thing?  It continued around until I had a nice organic 3D shape.  I think in Geometry terms it's roughly a saddle.  Euclidean space, baby!



LEGO Finds - Calendar Week 15

Finally!  After several weeks of very little to nothing, there was a small haul.  All over the map too.  First, a black City briefcase and dark bley knit cap.  Then a Bionicle mask, weapon and random piece (hooked on the Technic ring), plus a Knights Kingdom helmet.  A Technic ring that's likely from the Ninjago spinner arena set.  Plus a Quatro piece and a Tub lid.


LEGO Tips and Techniques - Technic(olor) SNOT

Sometimes the most elegant solutions are not the sexiest.  Which is fine if you're hiding your SNOT.  Brackets, headlight bricks and travis bricks are very useful for 90° and 180° solutions.  I've previously highlighted what is probably the tightest 180° solution even if it doesn't have grip as good as a typical connection.  I am personally guilty of using the aforementioned pieces to do some blocky kludges.  I grew up with a lot of basic parts and the headlight brick and old 2x2-2x2 bracket were my only solutions.  Even the technic sets I got were simple but we did have those irreplaceable 1x technic plates.  How I miss those.

"Why did he make that clunky segue into Technic?" you may ask.  I'll tell you why.  With only 5 technic(y) parts I'm going to introduce a host of 180° SNOT solutions that are compact and effective.  First, the 2L axle.  Next, the full bush.  There's also the 1x4 technic plate and the 2x4 technic plate.  Finally the 2x2 round plate which isn't technically technic but has an axle hole in the middle.  Other minor players may make a cameo appearance.  Let's begin, shall we?

Solution 1, the 4H stack, studs out.  (Stolen from Inspired by Courtesy of ricolego)  Even though the 4H plates are a touch shy of the 2L axle, the nubs will nestle into the bottom of a tube just fine.



Solution 2, the 2H axle grab, studs out.  This is an extension of the above solution with 2 2x4 technic plates sticking out for a lower profile 180° SNOT.


Solution 3, the 2H slim jim, studs out.  No AFOL should be without a few of the old school 1x technic plates.  The plates fit perfectly within both collars of the half pin.  Be aware that the stud on the pin sticks up 1/4 plate higher than the studs on the technic plate.  A flick-fire missile would also work here for extra bar goodness.


Solution 4, the 1H slim jim light, studs in or out.  Those holes on the ends hold a wealth of uses.  Here they snugly hold a stud from either side.  However don't rely on being able to insert a stud into both ends with perfect results.


Solution 5, the 2L "dumbbell", studs in.  I was too lazy to dig up my technic bushes so I used a technic axle connector instead.  The same results are achieved.  This is the simplest version but there are several flavors that can achieve other angles and layouts.  For bonus points the technic pin connector can be used over studs.


 Of course there are as many solutions as there are AFOLs out there.  This is a sampling of some of the better ones that I have used.  Think you got a better one?  Describe or link to it below.
