Nice Idea LEGO Techniques – Headlight Bricks

Excuse my summer time burnout. I may be a bit sporadic over the subsequent couple of months. That will simply make you look ahead to my posts all of the extra, proper?  Riiight.

Headlight Bricks seem to have extra nicknames than different items. Some name them headlight bricks after their authentic use, some name them Erling bricks. This is apparent since Wikipedia tells us that Erling is a Nordic male title, which means “Heir of clanchief”. OB-viously! But it actually tells us extra in regards to the origin of the brick. It was nicknamed for the LEGO Designer Erling Dideriksen, who invented this component in 1979. And regardless of that, the mannequin store nonetheless calls it a washer brick, though the Pick a Brick calls it an “Angular Brick 1×1”. Angular? Like 90° perhaps. What if we acronymize this title to HEWA (headlight/erling/washer/angular)?

Current research block, my piece de whatthehell…

Now that that is settled, let us take a look at the geometry of the brick. After the final Reverse Engineering Challenge, I received right into a dialogue with Sheo, one other superb builder and brick thinker. Whereas I had been bricks with their nominal width of eight.0mm, he has been them for his or her ACTUAL width of seven.8mm. All bricks have a zero.1mm tolerance on either side to cut back binding when positioned subsequent to one another. When bricks begin getting used sideways, attention-grabbing outcomes can occur.

The HEWA brick is usually turned sideways and used for a SNOT method. This implies that the course of tolerance is getting caught into one other dimension. Usually. This entire factor happened as a result of I made a daring try to point out that studs are NOT 1.6mm tall as is often thought. They’re a mite taller and I do not imply due to the emblem. Even hole studs have collisions. Sometimes. But why not all the time?

Let’s research the HEWA brick. Nominally it is eight.0mm throughout. Actually, it is 7.8mm throughout. At the bottom. For the brick portion, it is truly 6.4mm. You anticipated it to be 6.3mm? I did too. But the block is definitely 6.4mm to permit it to be the very same top as two plates. That was some ahead pondering again within the good previous days. So it has tolerance reductions within the upright place, and corrections within the inclined place. Assuming the stud is actually 1.6mm tall, that might clarify why the aspect stud stands proud a scoche. But it isn’t 1.6mm tall and we’ll tackle that one other time.

So what if we flip the brick sideways? The geometry is just like one other newer piece, 99207. I’ve drawn the studs to line up, however do they really? We’ll take a deeper look into the HEWA brick’s relationship with different items within the subsequent few installments of this weblog collection.
