    Procrastinating on difficult work

    I get excited by challenging projects, the initial roughing-out is the best part. I tend to lose myself in this work so before beginning I ensure nothing else is due that day, warn the wife that I may be late, warn teammates to leave me alone, charge the headphones, and load up on stimulants...

    41 Years old looking to go back to school to receive MS. Looking for advice!

    A MS is a fluff credential, its not going to make you a technically competent engineer nor develop the skills mentioned. The only way to accomplish your goal is to jump into a design or analysis role at a decent company and work your backside off the same as any recent college grad. CAD/FEA/CFD...

    Part numbering conventions - what's the best practice in aerospace?

    That's the default for how most PLM/PDM systems assign p/ns. "Smart" p/ns cause a ton of issues on the shop floor. They're long, and once you get beyond 5-6 digits humans struggle to accurately read, write, and remember them, or even distinguish between similar p/ns. That extra length causes...

    Part numbering conventions - what's the best practice in aerospace?

    5-6 alphanumeric, random digits is the norm. "Smart" part numbers are among the dumbest, most costly ideas pushed by MBAs in recent decades.

    BOM for 2 different sites

    Smart part numbering has to be one of the dumbest, most-hated things that some companies do. A simple 5-6 digit alphanumeric is easy to remember and distinguish from others. Smart p/ns are usually ungodly long, difficult to remember when you're on a ladder pulling parts or underneath a...

    Sheet metal Spring, Force to Compress To a smaller Diameter

    I would search Machinery's Handbook and other texts for clock springs, and if all else fails try Google.

    BOM for 2 different sites

    Trash the multiple C/E/M BOMs and smack whoever proposed that nonsense. Normal practice is to use levels/layers and p/ns as needed for inspection in a single BOM. Your example would look something like: Non-saleable engineering "buck" contains all variants of product ^ Saleable product is...

    Is there any good CAD software?

    Lazy cultures can be difficult to overcome, but ultimately lousy modeling standards/practices should be easily traceable via PLM or otherwise. A good practice in that regard is to require multiple managers to approve releases. If another team's part changes, obviously you want the potential...

    Low Profile SAE Mounting Adapter?

    Yes, flange adapter plates are commercially available.

    A Conceptual Modification to the Continuing Education Requirements

    IMO the ABET curriculum cant get much further from reality bc: 1. Basic skills courses like drafting/print-reading, CAD, risk & failure analysis, PM, etc are not required, nvm advanced ones like FEA, CFD, etc. Many graduate with no useful skills bc of it. 2. Most of college is spent on paper...

    Teaching Load Paths Used in Structural Engineering Discussion

    I had to color load paths/vectors on all FBDs starting in first-semester Statics, red for compression paths and blue for tension. One of the first examples I remember are linkage clevis/yokes, the question was why the "legs" can be so long without material in-between (ala the green block in the...

    Low Profile SAE Mounting Adapter?

    PTO adapters are commercially made by many companies. Engine and pump manufacturers usually have a plethora they’ll sell bc it enables sales, so I’d start by calling your suppliers for their pricing then check the aftermarket.

    Is there any good CAD software?

    Many of the "quirks" in CAD modelers are due to machine learning (AI) and changing modeling techniques. Years ago we had to mathematically define/constrain everything. Today a lot of design is done by pulling on flexible bodies and generative design.

    Is there any good CAD software?

    I prefer Pro/E but have also used Catia, Solidworks, NX, and Inventor professionally, had intro to AutoCAD in college, and farted around with Fusion and other hobby modelers after hours. There's always somebody faster/better, but I can hold my own and quickly/easily model anything. IME the...

    10 years' experience mech designer. What is next?

    Hire into a major international company over there, work a few years, then relocate to another of their offices in whatever country you want to explore. Obtaining a work visa for a new employee without well-established employment is very difficult bc the relocation is generally a personal...
