    rewire - square headed nuts?

    I'm rewiring my Champion, and I'm in the middle of doing the "behind the dash" wiring. I've never seen so many square-headed nuts (#10 x 32) in my life, used for wiring terminals. Makes it very hard to take off/put on the nuts since they are so close together. Did they do this to keep the mechanical guys (with mechanic's tools) away from the electrical stuff during assembly/repair? The assembly and repair staff must have had some sort of square socket to deal with so many of these.

    I'm tempted upon reassembly to substitute normal hex #10 x 32 nuts. Anyone else see a problem with this?

    Anyway, rewiring is going well, and with any luck some of the car will work upon first attempt after I'm done.

    By the way, while the instrument cluster is out, I'd like to do some internal clean-up inside the glass. Any suggestions on how to do this?

    I had no idea that they were not hex, are you sure they were not swapped at some point ?

    Could have been swappped by PO, but the harness is original (deteriorating cloth insualtion, frayed copper showing everywhere - amazing it ran until now). Nothing else looks swapped out behind the dash. I can't imagine why any PO would swap these, but I just bought a box of hex #10 x 32's and they're going in. My fingers are all cut up from manually twisting these sharp square nuts off.

    JDP - do you have any suggestions about cleaning up the speedo and guage displays? I'm going to take apart the insturment panel tomorrow, and clean the inside glass, and shake out some of the dust. The black background for the instruments has some discoloration and/or rust (strange, since the entire car is rust-free). I want to spiff this up while I have everything apart.

    Yeah, I've never heard of such myself! Of course, hex will do fine.

    "By the way, while the instrument cluster is out, I'd like to do some internal clean-up inside the glass. Any suggestions on how to do this?"

    CAREFULLY! Be careful not to touch the faces of the instruments, it could cause the color to deteriorate or discolor over time. I HAVE taken one of these clusters apart and sucessfully reassembled it, Just be slow and meticulous about it. There may be some paper gaskets between glass(es) and case that will turn to itty bitty pieces when distrubed. Are you good and cutting out paper dollies???[}]

    Speaking of hex nuts, if anyone needs them, I bought a 1000 10x32 nuts on ebay and that might be more then I need.

    John,
    Do not let your nuts go to waste. You may feel you don't need them now but the time will come when you will wish you used them more.[)]

    Sounds like one of my staff meetings... start out with a serious topic and in 5 minutes somebody's bragging about how much "nuts" they've got! Thanks for the warnings/advice. I'm going to try to get some of the collected dirt/dust out of the instrument cluster. I'll try camel hair brush and I'll wear gloves so I won't leave any oils as Mr. Biggs suggests. Sounds like a CSI job...

    The last wiring job I did was on a '51 Commander. All the nuts on the back of the guages were hex nuts as they should be.

    I think there was a time when four sided nuts were the standard in hardware. I have no idea if 4,6,or,8 sided nuts were or were not used as original equipment under your dash. I do know a Model A man who needed SOME 4 sided nuts in a restoration to be authentic.

    All the nuts in the body of my 27 Dictator are square. All the mechanical stuff is hex. I think they stopped using square hardware when they went to all steel bodies. Incidentally, you would not believe how hard it is to get a slotted head screw out of an 80 year old piece of wood suffering from terminal dryrot.

    Square nuts were easier and cheaper (less expensive) to stamp out. Most likely thats why they were used in many applications.
