    Who Likes Ships? We Have Aircraft and Trains.

    I boarded it in NYC 1960 while docked. It was a big deal. No TSA, metal detectors, Gold star ID, etc., we just walked on.

    Cracked trans crossmember

    There is a window, and it must be a prompt one, sooner the better. Not sure why a valve cover even needs baking, we are assuming here they were steel. And baking is not any form of heat treatment, in that the metal is not changed in anyway, and why it's a process for steel recommended without...

    Cracked trans crossmember

    I was under the impression at 450F chrome is beginning to yellow, but that was not my primary concern here, it was more that the chrome process effectively seals the hydrogen in, preventing the normal post plating baking in getting Hydrogen out of the metal. Bottom line, regular chrome does not...

    Pinion Yokes - What to Use

    Why the round tip? Looks like a conventional zerk grease fitting installed in the cap?

    Cracked trans crossmember

    I was under the impression chrome plating traps hydrogen embrittlement and resists the low temp baking corrective process? High temp discolors the chrome.

    Pinion Yokes - What to Use

    My suggestion above has nothing to do with the inaccessible center of the u joint. I'm talking about the center of the end cap(s) and very easily greased with no disassembly. If one wanted a true solid uncrossed drilled u joint, then use four zerk fitted caps

    Pinion Yokes - What to Use

    So, the solid vs greaseable joint discussion, is the problem where the zerk is located on the joint or the fact the joint is also completely cross drilled? Seems like a cross drilled joint could be very easily greased without the zerk accommodation if the zerk was located in the end cap in 4 or...

    Cracked trans crossmember

    We can assume I believe if those reinforcements are indeed factory, they discovered the problem after the first rendition was in the field, and decided it only needed a small upgrade to resolve, the when and how of the that is above my pay grade. :)

    Cracked trans crossmember

    Interesting. The cracks indicate to me the real world "weakest link" in the design. I suspect the mirror pair of cracks are likely caused by the TB's repetitive loading. During fabrication those would be maybe compression bends, not likely to cause cracking? The single crack is puzzling, because...

    Let's talk more about garage door openers.

    My daughter on my suggestion 3? years ago installed one and they love it. Code enforcement/inspector had never seen one and he was impressed. So, I'm interested in what I am missing here.

    Curious about the zinc in break in oils......

    What might be happening here is the additive, a compound containing Zinc, does break down, but the element zinc does not leave, except by what might be found in the filter or at an oil change.

    How often do you replace your laptop computer?

    I have went thru maybe 6? Chromebooks and 5? laptops in past 12 years, I like the chrome books. I am tough on electronics, I get a problem, I toss them, buy new. I mostly use them for travel and internet only, anything important is on a non-internet connected desktop computer. I also easily have...

    Curious about the zinc in break in oils......

    "If your entire oil supply is so coagulated" That is not the level that is required to cause a large filter oil bypass condition, what is needed is just enough to block the filter media. And what will flow thru bearings I believe in most cases is much larger than what most filters will...

    Curious about the zinc in break in oils......

    Well, I assume if one has a stopped-up oil filter that is bypassing 100% or even the earlier mentioned 88% of the oil flow, something must be visible to the nmaked eye on the filter media.

    Curious about the zinc in break in oils......

    Except it is still unknown what we are maybe trying to avoid filtering here flies or pigs for instance, as I have no idea what coagulates maybe forming in our DIY oil cocktails. This whole line of thought got derailed partly in replies #1 &#7 IMO, and aptly debunked since. I do have a question...

    Curious about the zinc in break in oils......

    The point of zinc stopping flow thru an oil filter was questioned very early on in this thread and evidence was never shared to back up that contention. I can't dispute the concept of zinc "dissolving" in oil, but I do question if other additives/detergents' intentionally or coincidently might...

    Curious about the zinc in break in oils......

    I was under the impression AP SN rating does not directly address "detergents", it rates more performance of the oil and the quantity of additives such as zinc. Detergents are left up to the blender as long as they do not obstruct the oil from performing to the standard being sought. BTW, I...
