    Cube nuts?

    Thanks for the link. Those look nice too, maybe for a different board design.

    Cube nuts?

    Yeah, I need to houseclean for sure, but if I can find a good supply of them, they would be useful for other projects. =)

    Cube nuts?

    lol, yeah, kind of. I just found this link: http://www.newark.com/ettinger/05-60-533/cube-standoff-threaded-m3-10ni/dp/59M4074 I need to take a measurement since its overall dimensions seem a little big.

    Cube nuts?

    I bought a PCB that came with some cube nuts that were threaded in two directions at 90 degrees so they could be used as a kind of bracket to hold the board in place in a metal U-bracket. I lost them and figured I could easily find a replacement. I think the size of the threads were something...

    Loosely held rotating object tendency to stay with CG

    Thanks for the responses, so there is no difference in pushing or sliding the disk when it is spinning or if it were static. The only thing holding it in place is the friction from the clamp, which would also be the same for both scenarios.

    Loosely held rotating object tendency to stay with CG

    To paraphrase: What force would be required to overcome the balancing of the disk when it is rotating at its CG (or central axis)? The axis of rotation for the disk is fixed by say a rotating motor hub, and the disk is loosely held by a top and bottom clamp. The motor hub rotating axis is...

    Loosely held rotating object tendency to stay with CG

    I am trying to think about this scenario, but not sure what to think. Let's say you have a loosely held (low friction) disk object held between two clamps and spinning on a hub at a certain RPM. As the disk-shaped object is spinning, it is perfectly balanced on its X-Y CG. Does the rotating...

    Button head plain fastener

    Dome cover heads are not really what I'm looking for. If I could find the fastener, I would tighten a nut behind it. It's a decorative application, so not much torque is required.

    Button head plain fastener

    Thanks for the replies. I am not looking for a carriage or coach bolt. The fastener head is driveless. Here is an example of what I am looking for, but this supplier is in the UK (I'm in the US), and the thread is not standard (to me). This example is the closest thing I could find...

    Button head plain fastener

    I am looking for a button head fastener ( about size #8) with a plain, smooth, polished, head... sort of like a carriage bolt, but fully threaded to the head. The application is sort of decorative. What is the proper name for this type of fastener, and does anyone have a suggested supplier? I...

    Stainless Framing?

    Does anyone know of a product similar to 80/20 or Bosch framing but in stainless steel?

    Standard Sleeve Bearing Sizes

    Anyone familiar with "standard" sleeve bearing sizes? I am looking for a replacement parts, and the documentation specifies bronze or synthetic sleeve bearings sizes A and B. They have a 1/8" ID and a 3/16" OD, which I haven't easily found. The lengths are not critical. Does someone have a...
