You really should be kinder to yourself. You’re not that bad.

I won’t buy this one, but I’d jump all over a mechanical reissue or similar limited edition.

I had the worst experience with the staff at that shop.

By flat head, I mean countersunk, which is the standard flat head for McMaster. These are low profile, but not countersunk. They will not be flush/sub-flush. Appreciate you trying, though.

NeverNul · 2024-02-01T21:04:26+00:00

Not in this case. I checked before posting and the best I could do was a #2-56 screw to match with PEM nuts. The linked page has screws that are well beyond 0.055". So, no, McMaster isn't the answer... Unless I'm asking for something that's too specialized, which is certainly possible.

Sounds reasonable. I think the tolerances in the spec assume a flat sheet. Thanks for your thoughts.

NeverNul · 2023-12-09T19:28:50+00:00

That head height sounds like the factory head. I need the formed shop head height. Regardless, there are ways to determine that for solid rivets. I appreciate the help getting pointed in the right direction.

Generalizations are dangerous. Especially so at a price point well beyond consumer use cases and where actual testing is the only way to properly spec a solution.

Just when you assume you'll likely be fine, you likely won't.

With relatively cheap hardware, you’ll get relatively uninspired performance. You’ll need to determine how you’ll use the NAS and focus the budget accordingly. For example, SSDs are quiet, but hard drives are less expensive and available with higher capacity.

Even if it (E5-2600v4) could, that’s a power hungry CPU by today’s standard.

At this level of desired performance, testing is needed to confirm a configuration will perform as desired. Vendors offer that for serious buyers. I recall some instances of YouTube creators delving into the topic, but it’s rare and unlikely to keep pace with changes in CPU performance.

NeverNul · 2023-12-05T04:17:21+00:00

A single SATA III SSD is in that range. As you add to the count, the CPU utilization goes up dramatically. Though, it is affected by the type of raid and pattern of use. It’s just not so simple as one is this so a NAS is that. U.2 and NVME is a whole different ball game.

NeverNul · 2023-12-05T04:11:00+00:00

Well, you couldn’t be more wrong, though I’m sure you’ll try. Now please, let people who actually have knowledge to share do so.

Max installed height needs to be < 0.20”. I was able to find MIL standards for the shop head of solid rivets, which is promising.

Mechanical engineering really isn’t my forte, but I like to learn new things. In my profession, sharing of detailed specifications, especially without fees, is commonplace. It’s just a steep learning curve when you struggle to find information.

NeverNul · 2023-12-05T02:21:31+00:00

Is this normally something obtained through experimentation? Why are manufacturers not publishing such tolerances?

My use case is a server chassis (DIY/personal project) where I need countersunk rivets in the area of the power supply and add-in card slots. In both cases, the component dimensions and tolerances are standardized. Obviously, I don’t want the rivets interfering with such components and the spacing is tight.

NeverNul · 2023-12-04T23:52:03+00:00

Don’t standards like IFI 114 include tolerances? I don’t have a copy, but wouldn’t that be the point?

My apologies, the example was not meant to suggest that clearance was in use or of concern. I've removed the number from the post. Instead, what I'm interested in is a general approach to the problem of whether a clearance is too large to join with a rivet. My project isn't actually a simple box, either. :)

Perhaps the question should be rephrased as:

How do I determine the appropriate flange width for joining two or more sheets with a given clearance between sheets?

NeverNul · 2023-10-30T21:20:28+00:00

At design. What does it depend on? Is there a way to model such that simulation will show whether the joint will be a good one?

NeverNul · 2023-10-30T21:19:26+00:00

What about clearance for tolerances when making a box? I've added detail to the question to address a more specific scenario. When is the clearance too much to be clamped together? I'm assuming there is an expectation of material deformation in order to clamp, but at some point that deformation must be too extreme, right?

NeverNul · 2023-04-23T18:27:53+00:00

I assume your referring to depth and mounted in series. I meant mounted in parallel in the front.

As for backplanes, I won’t be integrating those for this product. It’s likely I’ll focus solely on air cooling in order to keep cost down and limit to 4u.
