This idea was originally from Nathan Schmoekel on a facebook group called pocket top talk. His design has been replicated by me and several others, and I can confirm that his top can spin for times exeeding 5 minuets.
Let's get started!
Step 1: Parts?
1) a 10x32 button head Allen bolt, about an inch long will do.(be sure to check that they are quality bolts and have no lip around the key hole so that you can drill the hole on center, the one I made in the 'ible was way to wobbly due to the hole being off center)
2) 3 3/16inch to 1inch washers.
3) a 10x32 nut.
4)a 5/32 ball bearing
(NOTE: of you can find all these in stainless steel you won't have to worry much about rust)
5)some green painters tape.
6) a cheap 5/32 drill bit.
( if you have a digital caliper you can check that the drill bit is just slightly smaller than the bearing, because you want the ball to be held in by a press fit. Nathan also suggests a #28 drill bit.)
7) a drill.
9)a1/8inch hex key.
Step 2: Assembly: Stage 1
First thing we notice is that the washers won't center on the bolt well enough to get a good smooth spin. You don't want tight fitting washers because they too will be slightly off center. So what you can do is use tape to get it near perfect.
Start by measuring out the thickness of the three washers stacked together. Now use that measurement and mark the tape and cut a long strip of that width. (try to aim for a little taller to be sure the washers can fit tight.)
Warning! This may take several tries and will test your patience.
Now that you have a strip of tape, start wrapping tape snugly abound the bolt keeping the edge of the tape flush with the head of the bolt. after you have wrapped the strip of tape enough to be thicker than the hole of the washer cut off access tape. Now, here is the tricky part, you have to test fit the washers and see if they will got on without to much force. They most likely won't on the first try, so you have to remove small amounts of tape in till the washer fits just right, don't try to force it if it won't go, take your time and go slow. It may take some force to get it on snug, but the tape should not be wrinkled or crushed, otherwise your top will wobble and drive you crazy.
Step 3: Assembly: Stage 2
Step 4: Assembly: Stage 3
After that pop the bearing in and your all set.
Note: Because the top I made here had issues with a ball being off center, I took a picture of the good one I made before for the last picture.
Step 5: Final Thoughts
Thank you for reading, I hope you enjoyed this and try making one yourself.

Step 6: Inspirational Tops From Others
The hobby of making spinning tops made out of hardware parts is rapidly growing. Here are some photos of tops made by fellow spinners.
Here are some details about Jeff Brown's hardware top from Jeff himself:
"Ball bearing, SS Allen bolt (1/4-20 I believe), bronze washer, copper washer, 6 zinc washers, copper washer, bronze washer, zinc castle nut, zinc threaded wood insert. I got undersized washers and reamed them out to JUST big enough. Then drilled out the Allen head for the bearing. Drilled too large and had to epoxy the bearing."
Some details about Nathan's top: Assembled from hardware with two copper washers in the middle, finished on a lathe, and a machined stem grip to finish it off. He sells his for around $30. spin time around 6 minutes+
