Your Lego Mistakes

brick_heck · February 2016

What are your Lego mistakes? By mistakes, I mean building errors, misplaced pieces etc.

Yesterday I finished building #75094. I started it last Sunday, and dipped in and out of it all week. As soon as I put the front on, I went to lower the wings for the first time, only to discover that the 1x12 I put on from page 13 (out of 153 pages) is out of place and one of the wings will not go down all the way. I now have to dismantle is from the underside to move it just 2 pegs. Doh!

So, what are your building mistakes? I can imagine something out of place early on on one of the larger UCS models can be a right pain. At least the Imperial Shuttle I have just built is not that big. But for my second Lego set I've built in over 20 years, this could be tricky to fix.

To many to count and thankfully mostly minor and easy to fix. I did use the wrong gear on one of my recent technic models but I suppose the gears I switched were similar in size at it appears nothing is dysfunctional. That would have required almost a total demolition which I may do in the end anyways to build the alternative model.

Built my #01094 Emerald night loco misjudging the dark grey with black, or vice versa, and discovered it a few pages later when I realized that I did not have enough of that color to finish a step...
I would imagine that is the most common error you will see here, misjudging a color for another as IMO LEGO instruction books do not do a good enough job representing the color that is to be used when you have different shades of a specific color.

Recently put together #8480 Technic Shuttle and messed up the gears on the rear wings. Didn't even think to test them after putting them in but have no intention of taking it apart and re-doing it, the instructions on the old technic sets are a nightmare to follow compared to the recent sets.

I've used the wrong shade of a piece on a number of builds.

Yup I get the greys mixed up or dark grey with black. I did it just last week on Wall-E as it happens.

My first Technic build for over 15 years (considerably more complicated than I had been used to!) - I put one of the driving rings in the wrong way in the gearbox of #9396 and didn't test it or realise until quite a way through the build. Literally had to tear the thing down and start almost from the beginning....

I have a bad track record with AT-ATs...

Building the UCS motorized AT-AT I accidentally put in all the cogs backwards, which resulted in the AT-AT moonwalking across the ground instead of moving forward. Took a long time to correct this mistake.

Second was when building cavegod's 6,000+ piece AT-AT. On the main body, I put part of the technic in wrong... so I had to take apart the entire body to redo it (which is no small task). In addition, I had to make countless adjustments to get the entire beast to finally stand under its own power.

I remember being very excited building the Volvo loader #42030 - my first fully controlled RC technic model.
Took my time as I like to be sure that all functions work smoothly step by step. Finally finished the build after one week and powered up.

Surge of adrenalin...
Tried the steering: perfect!
Raising/lowering & tilting the shovel: perfect!
Driving train: no movement at all... argh...

Took a good look at the driving train compared to the instructions, and found my mistake.
Accidently swithed the two gear wheels (4237267 & 4640536) on page 13, step 4, (out of 323 pages) and never noticed. Not the easiest place to get at - so basically took the whole model apart in small chunks, fixed my mistake, and got it up and running. Took about two hours to correct.

Most definitely my worst mistake!
