Adam Savage builds Lego's new Saturn V/Apollo Mission model rocket

In April, Lego announced its fantastic new NASA Apollo Saturn V model rocket set. Based on a Lego Ideas submission by a builder named saabfun, it's a 1:110 scale model of the real thing. Of course the Saturn V was the workhorse rocket that took astronauts to the moon beginning in 1969 and delivered Skylab to orbit in 1973. Watch space geek Adam Savage and his Tested colleagues tackle the assembly!

Lego.com is out of stock but you can buy it from scalpers on Amazon here.

Essential tool for spoon whittlers

I got this Morakniv hook knife ($25, Amazon) last week so over the weekend I tried it out by making a couple of small spoons. The hook shape makes it easy to whittle out the concave part of the spoon, which is almost impossible to do with a regular knife.

Whittling spoons is fun, and they make nice gifts. I give most of mine away and people remark, years later, that they still use and like them. If you are just getting started - I have two book recommendations: Heirloom Wood: A Modern Guide to Carving Spoons, Bowls, Boards, and other Homewares, and The Artful Wooden Spoon: How to Make Exquisite Keepsakes for the Kitchen.

Maker Update: plastic center finder

This week on Cool Tools' Maker Update by Donald Bell: Bluetooth controlled lights for your skateboard, tracking your hamster health, a classy Kaleidoscope, a tool for finding the center of a circle, beautiful circuit diagrams and Maker Faires. Our featured Cool Tool is the Robert Larson 800-2875 Plastic Center Finder.

I learned about this tool from maker Ben Light, who uses it to drill out the center in the tin can robots he builds. Online, I see a lot of videos of jewelry designers using these. Woodworkers use them on finding centers on dowels or centering up work to chuck into a lathe.

They also work for finding the center of squares. Using the side with the 90-degree angle you can mark out the center of a square. This is especially useful on smaller material (like small tiles where a speed square isn’t as helpful.

The smaller, 60-degree angle on one side of the tool is intended for use finding the center of hexagon shaped material. I've yet to come across any hexagons I need centered, but I can imagine it being useful around a geodesic dome build.

I also have to just say that this is one of those tools that I simply find aesthetically satisfying. I probably only break it out every couple months, but every time it catches my eye it makes me smile.

This high power lighted magnifying glass is only $2

My daughter and I set up our home maker space this weekend. On thing we did was organize loose components: capacitors, integrated circuits, diodes, resistors. The markings on some of the components (like the tiny capacitors) are so small that I can't even see them, let alone make them out. This little battery powered illuminated magnifier was just what I needed. It made the markings easy to read. It's only $2 on Amazon with free shipping. If you buy one, you will use it.

Man invents chopstick-making kit for home use

The Chopstick Master costs $195. It makes perfectly tapered chopsticks and puts a diamond-shaped finial on the end. It includes a bottle of "food grade chopstick oil."

Rain Noe of Core 77 says: "If that sounds pricey to you, consider that if you brought it to any kind of fair or festival and set up a make-your-own-chopsticks booth at $10 a pop, I bet you'd pay the thing off in a single day easy." Read the rest
