    No Tom, it's a 182 with an O470L with an aftermarket STC'ed alternator that runs off a pulley mounted on the accessory case. STC'ed long ago on a planet far far away and no longer supported.

    Actually the 0-470/0-520 and bigger are the exception to the TCM rule. they do have belt driven gen/alt.

    but still, these brackets are steel.

    That STC is for the alternator up grade, it doesn't change any thing on the engine itself.

    why not? Happens all the time
    well, we just happen to be talking about sheet stock here.

    most likely
    Immaterial, the part is non-structural, and easily replaced. The OP stated that if/when it should crack again, he'll replace it.

    a bunch of them, and many have probably been welded.

    As a general rule, when welding a crack, material has been added.
    And when properly done, it will be just as sound as the origional part. If not better.
    If your only experience has been with some jackleg with a "buzz box" then you got what you paid for.

    After 12 years of successful service, I would think the person who welded it up, knew about heat related stress, and took proper steps to prevent that. It's actually easy and simple, if you know what you're doing.

    Reading this you would think welding is a poor substitute for Elmer's glue.

    The other day I noticed a tear in my loader bucket about 4 inches long right around where the pins attach the boom arms to the bucket. I could have replaced it, 200 miles each way to the dealer and $1500, IF they have one. Or weld it up in 20 minutes and go back to work.

    I'm sure the same logic applies to airplanes. Maybe the part is weeks away and you need the bird. Maybe the cost is just this side of stupid and you don't have the money. Maybe the part is no longer made. Maybe… I would sure as hell rather have carb heat that is welded than be without until I can figure out one of the other options.

    Most all of us trust our lives to welds on a daily basis.

    It works.

    I revert to my standard line regarding stupid debates:

    Who gives a ****?

    When you know every thing, all debates are stupid.

    So you have an aluminum bucket loader then? Or did you miss the parts where a few of us were talking about how welding aluminum is vastly different than welding steel? Welding heat treated and cold worked aluminum alloy reduces the strength of the metal by a large amount. If people don't understand this then they shouldn't be welding aluminium. By your logic someone with a broken wing spar should be able to just touch it up with a weld until they get it fixed. Good luck with that.

    These debates make me laugh... "I'm not a expert, but here's my opinion on why you'll fall out of the sky...."

    Reminds me of when I sold my last house myself, without a real estate agent. It was actually quite easy, and I saved a ton of money. So many people told me it was a bad idea...

    Real estate agents and the whole home buying process is backward and inefficient. If the market is going up, it is a good time to sell, if it is going down a good time to buy, either way they get their commission.

    You would expect them to work for free?

    Where did I say work for free? I simply pointed out my opinion of them, of how they play both sides of the equation. The great and continuing recession of 2008 was caused in large part by real estate.

    Perhaps by real estate, but more by the mortgage bankers giving government guaranteed loans to people who couldn't possibly repay them.

    Yeah... But, let's be truthful.... The realtors were on the front line of the crash, almost surely knew the clients could NOT afford the property they were selling /showing.... They then steered them toward a friend who just happened to be the banker, and another friend who was a loan processer, and another friend who was a crooked appraiser... It was a perfect storm being driven by greedy professionals and they got drunk on the massive amount of loan fees,surveys, banks got points and the realtors laughed all the way to the same bank with excessive commissions to deposit...

    For instance, here in Jackson, which is on the highest end of housing costs. During the heyday 2004 -2008, anyone with a pulse was hired as a realtor... They would list a property in the morning, by lunch several buyers would contact them.. They would literally pick the best and richest buyer, take them to lunch , feed them a 20 dollar sandwich and a 15 dollar bottle of wine .. They would look at the property, before 3 PM the client had signed a contract.... Also keep in mind housing here is /was insanely priced, starter homes were over a million, average sale price was 3.6 million

    So, in less then 6 hours they went from a "new" listing.... to a for sure commission of 200,000.00, and all their banker ,appraiser, survey, loan processor friends shared the transfer costs of 60,000-100,000... They too laughed all the way to their friends bank to make a deposit.. It was as close to perpetual motion as one can get.....

    Then................... The sun came up the next day and they did it all over again...:mad2::mad2::mad:.......:rolleyes2:
