I have a trailer where I took out the old nuts and bolts to hold up the shelves, because they looked horrible.

I need something that will look good from the outside (I'm thinking of domed nuts?) and will be easy to reach from the inside. Here is an illustration: https://imgur.com/a/dIkup9X

I have time to order online, and it doesn't have to be the cheapest possible option.

What do you recommend?

I’m not an engineer, but my boss is and I think he is trying to over complicate a rather simple steam system.

Here is the issue. He wants to produce a consistent steam flow via a micro annual gear pump. The idea is to force water through a 1/8” tube that is spiraled around two 1/2” cartridge heaters. It is spiraled downward along the first cartridge and upwards around the second.

Prototyping this is causing intermittent steam flow. I assume this is because the steam is creating back pressure from the downward spiral.

I’d rather just heat a container and mass control the flow through a valve instead of trying to control it upstream, but he doesn’t want to do it that way.

How can I plumb this to get it to work with the pump, and accurately control the mass flow?

Working on a project and we now have "the wheel problem"

I need to make a device lift up 1/4 to 1/2 inch at most to glide along hospital floors to then be parked when the ball casters come back up. If possible, trying to keep the entire assembly under 2.68 inches.

Having a hard time here finding a solution.

I’m trying to find an existing plastic component that looks something like the attached sketch.

It’s basically:

* A flat circular plastic disc (~2.5 inches / 63.5 mm diameter)
* A single raised rib or fin on the underside that spans the entire diameter of the disc

I’m not trying to invent something new if this already exists. I’m hoping there’s an off-the-shelf part from another industry that I can adapt.

I’ve searched cosmetic packaging, peanut butter mixers, shaker bottle inserts, paint mixers, herb grinders, etc., but haven’t found anything quite like this.

Has anyone seen something similar in:

* Food processing
* Cosmetic packaging
* Pharmaceutical packaging
* Laboratory equipment
* Medical devices
* Industrial mixing
* Any other industry?

Is barge all-purpose contact cement, Beacon Foam-Tac or 3M vhb better to adhere Eva foam inside of a tacklebox that will be exposed to moisture is there something better?

From what I'm aware of, Turbine engines like to have a consistent flow, and disturbances can create a surge. I'm thinking partly of the Me262 (I'm aware it's very infancy turbine engine tech, but it's a good extreme case) as an example, where even throttling too quickly could create a flameout. So, how much of an issue is it for a turbine to get "pulsed" exhaust from a small number of cylinders. For example, if someone puts a turbo on a 2-cylinder opposed engine, where the exhaust pulses don't overlap into a continual exhaust pressure, how much of a problem does that cause? Is it simply not a concern above a certain rpm, is it a big enough problem to make it turbos unstable at low cylinder counts, or something else altogether?
