Lead Sled reverse engineer

I am a big fan of miniscale cars like the ones built by Mad Physicist or the Arvo brothers. The challenge is entirely different compared to building large cars: instead of simply putting bricks on top of each other they require a lot of attention to the details to put everything in place. A special piece or a tricky solution has great impact to the model but it may need a lot of experimentation.

I considered building a replica for myself several times, for example one of the cars made by the Mad Physicist or the Porsche from the Arvos. Our friend the reverse engineer who helps to build the whole thing by looking at the end result only. From Lego bricks, of course.

So far I never got past a couple of thought experiments because apart from obvious details I had no clue how to continue building. But now I have decided to go on with the matter. Mad Physicist has built his '51 Mercury Lead Sled. On one hand looks very desirable, on the other hand it has several detailed photos so that I can have some hope. On top of this Ralph is very helpful and did not object and even gave some clues when I had questions about the details.

I started with Lego Digital Designer. Some bricks are unavailable and even more so some colors, but at least I have infinite supplies. Compared to other virtual building tools it is an important advantage that it models the physics of the bricks and does not let me build stupid things. This is how far I got (click on the album):
The colors are not quite right and some other details like the wheels are different too. But it looks promising. I am truly uncertain about some invisible areas but the external feels right.

When I am done with all details the next step will be Bricklink in the New Year.

  1. I am absolutely amazed at how much you were able to derive from pictures of the model. Some of the internal structure is different, but not at all important for the look of the car. Very impressive.
