Choochoo track of the week

Clover8: The Double Figure-Eight Cloverleaf

Supplies (Thanks to Auntie Amy and Uncle David):
2x IKEA LILLABO 20-piece basic train set
1x LILLABO Rail expansion set
1x LILLABO 12-piece train set w/ bridge, tunnel

This design is a variation of the popular cloverleaf layout, however it utilizes a double figure-eight. Similar designs had been attempted previously, but ran into compatibility issues near mid-track where female-female and male-male track ends meet. This problem is overcome in this design by using a secondary overpass, seen just to the right of the primary overpass.

Due to the proximity of the two overpasses, Van Hook shims were utilized on the primary to allow tank cars to pass under on the way to the secondary, yielding a tight 2 mm clearance. The innovative curved bridge lends an organic feel to the track, with order arising from the apparent chaos near the triple pass. As Owen put it, "Two tunnels!"

Take that, Thomas the Tank Engine!

"Whooo, whooo!" says Auntie Amy and Uncle David. Nice work, Johnsons. Good to see that the shims work well.

hi, what are shims? I want to try the same configuration for my three year olds ikea set. thanks!

Shims are just pieces of paper that raise a part of the track up by a small, adjustable amount. The amount can be adjusted by using multiple pieces of paper, or by folding the piece of paper. Have fun!

The Long Con

Hiding in Plain Sight

ESPN has a series of sports documentaries called 30 For 30. One of my favorites is called Broke which is about how professional athletes often make tens of millions of dollars in their careers yet retire with nothing. One of the major "leaks" turns out to be con artists, who lure athletes into elaborate real estate schemes or business ventures. This naturally raises the question: In a tightly-knit social structure that is a sports team, how can con artists operate so effectively and extensively? The answer is quite simple: very few people taken in by con artists ever tell anyone what happened. Thus, con artists can operate out in the open with little fear of consequences because they are shielded by the collective silence of their victims.
I can empathize with this. I've lost money in two different con schemes. One was when I was in college, and I received a phone call that I had won an all-expenses-paid trip to the Bahamas. All I needed to do was p…

On the Height of J.J. Barea

Dallas Mavericks point guard J.J. Barea standing between two very tall people (from: Picassa user photoasisphoto).

Congrats to the Dallas Mavericks, who beat the Miami Heat tonight in game six to win the NBA championship.

Okay, with that out of the way, just how tall is the busy-footed Maverick point guard J.J. Barea? He's listed as 6-foot on, but no one, not even the sports casters, believes that he can possibly be that tall. He looks like a super-fast Hobbit out there. But could that just be relative scaling, with him standing next to a bunch of extremely tall people? People on Yahoo! Answers think so---I know because I've been Google searching "J.J. Barea Height" for the past 15 minutes.

So I decided to find a photo and settle the issue once and for all.

I started by downloading a stock photo of J.J. from, which I then loaded into OpenOffice Draw:

I then used the basketball as my metric. Wikipedia states that an NBA basketball is 29.5 inches in circumfe…
