Heyco #SB-625-500 hard black plastic grommet. Split down the side, it is 11/16" OD, 1/2" ID to fit a 5/8" dia hole. It is 17/32" long OA with a small flange at one end, and a snap positioned 9/32" back on the shaft. Sounds about right for a 1/4" thick panel to us.

And we do mean micro. Sizes #61 to #80 (yes, that is twenty different bits) which are from 0.013 to 0.038 inches diameter!! The big boys sell a set of similar bits (carbon steel, like ours) for about $30.00!! Maybe theirs aren't from China.

You can start with our single aluminum tuning fork, 2-tined and 7-1/2" long. It vibrates at 256 hz, and is labeled "C". Or you can order the set that has (8) forks and a mallet with a rubber-tipped plastic head. The forks are labeled low-C to high-C and come in a fitted, latched wooden box. Unfortunately, C.J., who has perfect pitch, tells us that his pitch is more perfect than most of the tuning forks. He also says you can file the tips, tuning them to an electronic keyboard until they're perfect - and we think there's a certain cachet to telling people you tuned the forks yourself. But they are perfect, if you're using them for things like teaching principles of sound or driving the chihuahua crazy.

Another oldie but goodie. 5" high evacuated clear glass stand 3" in diameter at the top. A four bladed vane is balanced on a needle inside the sphere. Because opposite surfaces of the vanes are black and white, incident radiant energy is absorbed or reflected to a different degree. The result is a spinning vane. The brighter the light, the faster it spins. Simple, but compelling. Brief explanatory instruction sheet included.

It's nice to know that some things don't change. One is the Jacob's Ladder. Still made with (6) slabs of wood, each about 2" x 2" x 1/2", each a bright combination of colors, and all connected by a contrasting ribbon. Hold one end up and let the string of slabs dangle. When you flop the top block end for end, each lower slab in turn will flop end for end. Fascinating. Particularly if you are about 5 to 9 years old.
