Going Back To The Future again with Lego

I'm progressing nicely with the build.

I'm amazed by how intricate it all is and as I put little round pieces into square pieces and then into other sometime same sized square pieces I can't but keep thinking about how on Earth someone created this design. It's mind boggling. Yes, they'll have CAD software to help, I'm sure, but blimey.

Thankfully the build is broken into sections in the booklet and each of these sections has its own bag of Lego pieces. 

So, all the pieces needed for section 3 are in Bag 3.

I did notice that there are always a few 'extras left when each section has been finished.

Initially I feared that this meant I'd not put something in at the right time, and was reminded of working with my Dad back in the 20th Century as he fixed our car (back when cars were almost completely mechanical, with not a computer in sight). We'd always end up with a washer left on the curb when he'd thought he'd put everything back together again.

The other worry about the extra pieces is that if they can add some by mistake, could they also not leave some out.

I had a momentary scare when it came to Section 4. Some of the pieces weren't in the bag. Checking the box I was released to find that or some reason there were two bags for Section 4. Disaster averted. Phew.
