1968 Shelby GT350/500/500KR / Re: SHOCK TOWER CAPS
« on: December 16, 2021, 01:15:43 PM »
..............it is possible the "copper colored" spots on the OP's caps may be due to a fixture to hold the caps and washers for welding. The contact points for the fixture may have been copper in order to ground the part. The appearance could be influenced (more or less noticeable) due to too high a temperature setting on the welder. Basically, during the welding some of the copper was transferred to the part due to current flow.

     Seems a reasonable argument, particularly in the O.P. photos presenting "spots" of copper deposited, but in the second examples (post #17)?  In either instance the required welding execution was of the relatively small and limited area of what I would say are tack-welds; these requiring somewhat short duration application of current, and realizing the the potential heat required to heat the steel and melt and flow the copper particularly the sum in the second example..........well, I just don't see the current load in these tack-welds as being sufficient.    ???

     Of course in this discussion we have 'assumed' that the discoloration is 'copper', sure looks like it, but............ :-\

     But if all is so, then it surly was a F.U. execution!   ::)

................ would anyone "collect" one.

     I was considering buying a new Mustang Mach I back in 1976 (+/-?) to replace my '72 Mach I, but after sitting in the thing and looking it over more closely, even being tempted by the 'new' car seduction, I just ended up walking away.   :(

     In my opinion, the only good thing about the King Cobra's was that when pilfering through the junk yards, and spotting one, chances were good to find a 3.55 ratio Trac-Loc 8" rear.   8)

My guess is that it was a fix for caps that didn't pass inspection for proper welding.

   Possible, but it would seem odd to have components in original engineering outline to be welded, with the caveat that if these pieces should fail Q.C. then a brazing operation would be incurred as a suitable 'fix' substitution? :-\

   My experience in the past with F.M.C. is that they would have just tossed them out!  But now, if this had been Chrysler, well............ ::)

   And I'm not saying what is or was, but rather inquiring only on the if. ???

It’s called oven brazing gents


    In 'welding', this is the process whereby the parent materials are melted, and as witnessed in this case (but not always required) welding wire stock is added to the liquefied pool, forming a melded structure.

    In 'brazing', this is of a lesser heat involved process where the parent material is not intended to be liquefied but rather bonded with the use of particular "brazing-rod' materials.  Also one often will witness this brazing material about the periphery of the seam of the joined units, which here I don't see (maybe a better photo would aid in this observation) as I would expect, but?

    In the case of the pictured, I feel confident in saying there is a welding process presented, but is one saying that then, post welding, perhaps deemed insufficient, these assemblies incurred a further brazing effort; surly seems terribly in efficient?   :-\

That's hot !

     The vinyl/plastic tubing installation on three of the four carburetor fuel bowl breather extension tubes is interesting, perhaps problems with fuel percolation or?   :-\

He has a large following.

  It must be a Lemming event phenomenon!    ::)

  But one thing that is (should be) concerning of the car's preparation is the roll-cage execution, this with the cross bar below the dash.  I see this execution repeatedly, and it is solely as a matter of convenience for the fabricator that this is done this way.  The issue is, if the car should tumble with the occupant truly being restrained by the his belts, one's legs aren't; which will lead to them impacting this bar and often resulting in fractured legs!  :o

  And yes, I see the padding (maybe an acknowledgement of a concern?  ??? ); but don't think that in a significant bounce, where one might really be counting on that roll-cage, that it's going to make any real difference.   ;)

  So, even though one may very well survive the horrendous crash, with this bar execution it just might not be one that you walk away from!   ::)

     Yes, I would say an appropriately sized square drive socket would be best, but if one doesn't have one, or finds that the square really isn't of any real known size or made properly square even, then the best tool is a good Crescent Wrench of reasonable size for the job.   ;) 

     The advantage of the Crescent Wrench is that one can adjust the jaws, which are not parallel by design, until tight on the square of the fitting as this increases the area in play and moves some loading inward away from the corners (mounting the wrench for the proper direction of the rotation of course   :-\ ) this reducing the likely hood of rounding or fitting breakage.  Also realize that many of these plugs are of a casting and of poor material, (after all, it's just a (L.P.) pipe plug   ::) ) and therefore may be somewhat sensitive to excessive corner loading and impacts, whether be from a hammer or an impact wrench; and this fact makes the use of a serrated jaws pipe wrench a bad idea; believe me I've followed many a professional (D.A.  :o ) plumber who managed to gnaw the square end off a plug, and never get the plug out using a pipe-wrench!   :o

     After all, they're called a "PIPE WRENCH" for a reason; but then a good 'MONKEY WRENCH' would work well   ;) ;  of which I have a few just for that reason.   8)

     And unlike the last guy, don't tighten the plug as though your life depends on it, as it is only a plug, for a threaded hole, that is tapered in profile which creates an interference swaging fitment, and what is actually acting on this thing that if tighten properly (reasonably) is really trying to displace it; and vibration is going to have very little effect on this plug ("properly" installed), so guess again?  Also be aware that the use of thread sealers may, but definitely those with Teflon or the use of Teflon tape requires that one pay attention to the torque being applied as they act as a friction reducing lubricant which may lead to excessive tightening effect, and forget about next time or the next guy removing it, one just might (remember the tapered thread creating a swage  ??? ) crack the case casting!   :'(

     One last thought:  If a plug is "really in there", or rusted in place, consider the torque being applied in the effort to remove it, even if one has got a good bite on the fitting; as I said previously, there never was the intention for extreme force to be exerted, and past the reinforced area of boss proper the rest of the side of the casting is somewhat thin, push too hard, and I've seen the casting side break away,..........ops!   :o

     "Adjust gears in rear diff"

      I guess, it's being said that the car would capitalize on a different gear ratio?   :-\

      Or did it just lunch the rear end in that pass!?  :o

     GOOD LUCK!    ;D

     Years ago, I contacted several freight carriers asking why are we being charged exorbitant fees to transport fiberglass hoods?  The unanimous response was something along the lines of:  We know we're going to fucklle them up, so we charge more!  My response:  Hmm, so let me see if I got that right, your saying that your company is going to provide unacceptable service, so you charge a premium for it?     ???

      Between the costs of shipping, and the damage rate, we just gave up on the idea of shipping fiberglass hoods!    :)

Why are we doing any business/buying/selling with COMMUNIST China?

    Because the American consumer wants to buy stuff CHEAP!   :o 

    It's not the U.S. Government, although particularly with the current administration but also with the aid of others past, the pathway is made more possible, but it is due to the American people, and their lack of understanding or care for the ramifications of their actions; and due to the sum of individuals who are just not Americans, who are, even when they understand, intentionally doing their best to remain that way even though they enjoy the benefits, happy to just pick the bones of what is left of this nation.

    I'm for fare trade practices; the U.S. should adopt the very trade practices of China, as applied to U.S. products attempting to enter there.  Stop being afraid we'll hurt someone's feelings, whether that the Chinese or some liberals (aka. progressives, socialists, the true fascists, communists, anarchist and the just plain stupid  ::) ) and then you won't see nearly as much crap made in china occupying the retail shelves.

    But of course the Bidden aristocracy, along with many others of the elected and social elite might not be so pleased; but this issue is really caused by the populace, and truly it can only be fixed by those who choose utilize their economic power (that is before we've sent it all to china of course   ::) ) to dictate the will of the people.  Now that sounds a little like one is preaching nationalism, and I realize that in today's P.C. society this is radicalism, boarder lining on racism, someone will throw out the accusation of Fascism as this also popular verbiage but actually just showing their ignorance, and I am just an angry white male (is there anything lower?   >:( ), but all of this is the problem of our society!

    Look at YOUR credit-card statement, what did YOU buy, sometimes you just have no choice, but did YOU try to buy American made products or did YOU just buy the cheapest shyt, because it was cheap?    :o

Torque wrench? OK. What are the recommended values for the aluminum manifold vs. iron?


     The use of a torque wrench does not dictate a torque value, just aids in executing and the consistency fastener to fastener of the torque value chosen!      ;)

I just don't know


     I'm not to 'IN' to these grossly reworked body Hot-Rods, but somebody sure worked awfully hard on that one, and it isn't the worst rendition of a ground burdened rocket-ship I've ever seen; hopefully it has been saved by someone.    :)

     Besides, just think, the restoration costs will be covered when rented to the movie guys for the next re-make of The Jetsons !   ::)

That manifold, unfortunately, is very susceptible to breaking off that ear. I don't know if there is anything that you can do about it?

     The engineering of the unsupported flange in this area (260/289 cylinder heads) was based on the iron component which was fine; but with the substitution of the less rigid aluminum material for the intake manifold, and as a nonstandard production component probably didn't receive the engineering discover effort typically warranted, failures began to result.  Later Ford changed the intake face casting profile of the cylinder heads to provide support, but I wonder if this was thru observation of the difficulties experienced with the aluminum intakes, or due to similar failures of even the cast iron units with the propensity of air impact wrenches in use in the assembling of such items at the dealership service departments?    :o

     Don't over torque the bolts (particularly the end ones') and you won't have any problems; but remember, the torque values listed in the repair manual is based on the cast iron component!    ???
