    engineers biggest issues and wishes

    Biggest issues: Excess paperwork and ambiguously written regulatory standards, the former caused by the latter. Who has time to re-do everything in this day and age? Biggest wish: God willing, retirement in early 2021, I am super stoked about it. It is better to have enough ideas for some of...

    3kw fiber laser

    If you have to ask, you can't afford it [bigsmile] Seriously, your machinery dealer should be able to give you some pretty accurate costs. It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

    SLHV... ? What's the "s"?

    Super low heating value? It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

    Green New Deal

    "The US pollutes more than any other country . . ." Excuse me ?!?! It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

    Man Narrowly avoids a fate

    Casinos and lotteries notwithstanding, do rational humans sometimes walk past other kinds of buildings or structures, say, a café, for example? If he was unlucky for not having been killed, would he have been lucky(ier) to have been killed? Was he simply unlucky for getting out of bed that...

    Man Narrowly avoids a fate

    Eh, semantics. The bloke himself said it. "I cannot believe this, I was just shocked. I stopped at the cafe windows for a few seconds before crossing the road — I was lucky.” And indeed he was. Were it me, I'd feel lucky, as well. It is better to have enough ideas for some of them to be...

    Man Narrowly avoids a fate

    Wow, with luck like that it should be straight to the nearest casino! It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

    plug gage tolerance

    To clarify, centerless grinding IS very repeatable, PARTICULARLY in high ratio length/diameter work pieces. It's an excellent method for finishing plug and pin gauges. As opposed to between centers grinding, which does very poorly with high L/D ratio work pieces. It is better to have enough...

    plug gage tolerance

    First of all, centerless grinding is incredibly accurate and consistent, and produces very round and straight forms when done right. Very much within the realm of gauge quality work. Decades ago when I was in microhydraulics I would routinely receive batches of pistons and poppets that were...

    Green New Deal

    "I'd be interested to hear which bits people find objectionable." It IS a divisive topic, no two ways about it. Sorry IDS, no offense and no intention whatsoever of shooting you down personally, I was simply answering your question. I believe we have already been moving toward a better end in...

    Maybe not an engineering disaster

    Profit is not a bad thing. Without it there is no incentive whatever to be in business. The harsh whip of oppression certainly doesn't contribute to quality and efficiency in the long term, we've seen that played out time and time again. To wrap all Chinese companies into the broad sweep of...

    Porous Gold

    Passive diffusion of metal atoms through other metal atoms? at room temperature? It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

    Green New Deal

    Well, IDS, except that we're all to be become minions of an incredibly all-powerful socialist government, yeah, it's a brilliant plan. It's the same form of utter BS and nonsense that every despotic form of government has come from. "We'll take care of you" - "You'll be safe" - "Your children...

    The Bourke Engine Solved Virtually All Imbalance Problems In 1930 With Only 2 Moving Parts!

    The OP is nearly a month AWOL, but this has been a fascinating thread. Glad to see it continue. It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

    Auditing against "Parts"

    Could be a part of any set of standards, not necessarily just CFR(USA). Your member profile has you in Oz. Without further context, it's a guessing game and no meaningful answer can be given. It is better to have enough ideas for some of them to be wrong, than to be always right by having no...

    Manifold design

    Either The Lee Co. or Bird Precision could have a solution. Have used both of these company's products in years gone by in micro-hydraulic pumps and actuators, they are absolutely top notch in their field. https://www.theleeco.com/ http://birdprecision.com/ Disclaimer - I have no interest...

    Cast iron for gears

    With a cast iron or cast steel gear, you really must plan to do final machining on it. An as-cast surface is not acceptable for accuracy and surface finish. If you could get a gear set to run as-cast, your clearances and backlash would have to be set too far open, it would be very noisy, and...

    Question About Threads

    Here again, you may have to extrapolate your data. The chart from the German website has no useful information to a machinist. "B" indicates an internal thread, for which you need a minor diameter range, both upper and lower limit, and a pitch diameter range, both upper and lower limit. It is...

    Green New Deal

    There are some attractive bits in the planks of the Communist Manifesto, as well. AOC has but a wispy grasp of timelines, monetary reality, and how much government overreach will be tolerated by the right. It is better to have enough ideas for some of them to be wrong, than to be always...

    Question About Threads

    While it's debatable whether 5"-12 would be UN, UNC, or UNS, it is for the most part a legitimate callout. You may have to extrapolate the tolerance limits for the class 2. It is generally a better practice to have this data called out in black and white on the drawing when there is a...
