This spinning top is a quickie project anyone with a few tools and a little time could do in the home shop. I used a Taig lathe for 99% of the work, but a similar project could be done with a drill press and files. (It might even look better!)
The trick to making a top is that everything must Must MUST be co-axial. If you get something off-axis, the top wobbles. It's as simple as that.
To get things symmetric, I chucked some 1/8" brass rod in a collet chuck and cleaned up each end. A 1" diameter piece of Delrin was drilled through undersize, and the rod was pressed in. The whole thing went back in the collet chuck, and a bearing with a 1/8" ID was chucked up in the tailstock, and brought in to support the outboard end. The top was then turned down with a parting tool until everything more or less looked the way I wanted it. No real care was taken to hit exact diameters, but I did step the cuts by 0.050" with an 0.060" wide tool.
This top easily spins for over a minute. Makes a great present for a kid, young or old.
Of course there's more to tops than this. In essence they're finger-driven flywheels, so all the same calculations that can be used on flywheels can be used on tops as well. If you're after maximum efficiency, this top isn't it. Ever wonder why flywheels on steam engines were spoked? There's a critical point in the kinetic energy curve for a flywheel inside which having extra mass does you no good. You really want the mass out on the rim. Which is exactly the opposite of where the mass is on this one.
One of the most advanced spinning tops I've ever seen was the Quark, developed by Jim Lewis, the guy who started www.emachineshop.com - It had an outer rim made of brass, tungsten, or gold, and an inner core made of Delrin. If I remember right they had tungsten carbide tips. The real innovation with their top was that you could tune it for balance using weights inserted into pockets underneath the rim. Balancing was done using a laser pointer, which let you take out all the wobble in the top. They would easily spin for fifteen minutes or more.
They're still being made, and sold by Quirkle: www.quirkle.com/top/index.htm
They're clearly better than the one I made, but something tells me theirs took a lot longer to make.
Have fun in the shop!
A lace top cami. I am wearing a skirted suit with the jacket off, exposing my white cami and skin color bra straps.
I was about to tell Black Telephone that one of my first squircles was a milk bottle top but when I searched it turned out to be a milk bottle. I can't believe I've never posted a foil milk bottle top squircle. Well here it is, photographed on 27 Feb 2005, fifteen days after I joined flickr.

Esse esmalte faz parte de uma coleção antiguinha, e tava pegando poeira por aqui (além de ter ficado mega decantado, com esse fundo vermelho o_O e vejam, ainda está na validade).
A cor não tá muito fiel; ele é um pouco mais acinzentado.
Passei esse esmalte e tive uma surpresa ao descobrir que é jelly. =O
Tipo... eu ODEIO jelly =_=. Nunca vou conseguir passar direito, sempre mancha muito e as cores ficam ~variando de uma unha pra outra.
Tá, até que esse se manteve razoavelmente uniforme, mas não consegui impedir que manchasse, mesmo com 3 camadas.
A vantagem é que fica um brilho bem bonito!
Finally getting being able to walk to the waterfront again. Publishing the revised edition of my memoir/neuroscience book Concussion Is Brain Injury. Special moments with my mother and parents. Being taken to the ROM and getting to see the only preserved Blue Whale heart AND taking photos again.
Hair and make up done, the bride and bridesmaids were all ready for lunch before the main event. This was toast and gifts time.
I was able to attend Project Nunway LA this past weekend, the models, designers and venue were amazing, it was all for Charity and it was amazing!!!
I was lucky enough to hang out all day and get some great behind the scenes shots, then I was able to enjoy watching the show!
There are doughnuts, and then there are DOUGHNUTS. Top Pot makes my favorite doughnuts. I'm sure the doughnuts you like are good, but they're not Top Pot doughnuts. How very sad for you. This photo was taken at the Wedgwood Top Pot. Super yum yum yummy.

This top is based around the 'Bunting Scallop' fabric by Michael Miller, which was used on the sleeves and welt pockets, and inspired the neckline.
The rest of the top is ivory cotton, plus colourful cotton scraps from my stash. The pattern is 'Chloe' by Victory Patterns (shortened from a dress to a top).
