    The pic from sellers post before I bought it.

    Hi everyone,
    So I got this old 71 deluxe conversion last month and I been messing with it of course.
    Thought you might dig this progression.

    Am going to be fixing poor pickup routs.
    Useing hot hide glue.
    Resetting bridge.
    Fixing reamed screw holes.
    Replacing pots.
    Switching to vintage wiring.
    Doing a cleaning last resort trick (nitro finish).

    And probably more, that's why I got it, I can't mess with a cherry one ^,..,^

    IMG_0176.JPG IMG_0180.JPG IMG_0184.JPG Looks like I got my work cut out for me.
    This is how it showed up.

    This thing is filthy, the cutaway has black fingerboard goop covering it 1/16 in thick and its sticky.
    You can see a light version of the filth on the neck heel.
    It's also green with 40 years of nicotine mixed in layers of old wax.

    Time to get started.

    Cleaning this kind of gunk is a real pain.
    So I go for the zippo lighter fluid first.
    It's mostly naphtha and is a mild solvent that won't hurt old nitro.
    Three days an arm cramp and 200 paper towels later.
    Filthy WTF.
    Ok,
    This usually works but... this dirty grandpa needs something more.

    I see a stewmac video and try that.

    So I get some mild detergent (dawn dish soap) and start working lil bit on then wipe then naphtha wipe
    Wax on wax off dammit >.< this is just pushing the gunk from 1 spot to the next.
    Wax filth not coming off Mr. Mieagie.

    Next major net search.
    Nothing but snarky remarks.

    Until....

    ( I only tried this with old nitro don't know if it works on other paint)

    Daves world of fun stuff on YouTube.
    This f-in guy is too much.

    He says:
    Easy Off oven cleaner (non stinky kind)

    I'm like fk it I'll repaint it if this dosent work.

    Well 1 wipe and paper towel covered nicotine wax goop gunk all that crap.
    Don't leave it on wipe on and off.
    Follow it up with naphtha repeat buff.
    Shiny not sticky hell yeah.
    Thanks Dave ya grumpy azz.

    Keep it away from any metal like pots unless you want to age em. I don't know about plastic parts.

    Disclaimer,
    It worked for me. If you feel uncomfortable don't do it.

    IMG_0200.JPG This cutaway was black with gunk and I thought the bottom edge had been exposed to thinner but it was just filth that had blue jean texture in it.
    I think they stored it in a spittoon.
    Easy off took it right off and after naphtha buff surprised me with a shiny surface.

    I'm not done but it's useable for now.
    Sweet.

    IMG_0195.JPG So here's some bare wood.
    on this part I just used the zippo fluid.
    It took the stickyness and goo right off.
    Plays smooth.
    I'm still deciding what to put on it to condition it.

    So these controls don't work right.
    The tone only has effect from zero to one on the knobs.
    And they are all stiff and effed up.

    These tone pots are not audio type they are linear.
    This will cause the taper to be off making it seem like it's only working from zero to one on the knob.

    Time for new pots.

    IMG_0192.JPG Seems like this should be simple...

    Internet, too many aholes promising too much horse cr*p.

    Ok, so I get 4 short shaft Emerson 500k audio CTS pots from sweetwater cause they don't have regular CTS pots an the tolerance is +-8 and I got tired of looking.

    And decide to try vintage wireing.
    Which I like in this guitar.

    I looked at fancy pots and caps and all this stuff.
    I almost got some new Gibson replica bumblebee $112.00 pair caps.
    Was all caught up in this hype.
    So I YouTube em, and what do I see someone busting one open to see what's inside.

    LOL there's a 50 cent cap in there with a bumblebee candy coating on it.

    That snapped me out of it.

    I remembered that all of these paper and oil caps are made to function at certain tolerances.
    1 dosent sound better than any other if the values are the same.
    It's electronic parts not speakers.

    Now ceramic caps may not be as consistent because they can change capacitance with temp changes.

    lol I still am useing those old azz caps the values are probably off from age.
    I'll get some new ones later but I'll tell you this they will be regular old electronic store good quality $2.00 caps.
    I don't need my caps wearing a $111.00 pimp suit inside my guitar.

    Next,
    Look at this jacked up bridge and tailpiece.
    The tailpiece is flaking chrome that might cut my hand
    So time to fix that.

    I was looking at the net again LOL an 20 hours later I'm like @.@ bug eyed thinking why does everyone have to try and sell $5.00 worth of parts for $80.00 and up.

    I'm like fk-it.
    Rip this thing off grab a knife and start carving the chrome offa this thing.

    Find out it is aluminum, sweet.

    Sand off the scratches and babamba it's lookin good.

    Left a lil patina on it, relicked part $150.00 lol this is a freaking relic.

    So I ordered some maple and mohagany pieces for this dirty old grandpa cause it's been jacked up.
    I'm prepping this mess by cleaning out the holes then I carve a hole to fit a plug and get some pieces test fitted.
    I also cut a piece of hard maple to inlay into the body.
    Grab a file and start shaping.
    More test fitting an I'm ready to glue it in.

    I'm useing hot hide glue so everything has to be ready and test fitted.
    This glue is easy and cheap but the working time is under a min.
    You can get it at stewmac for cheap that can makes a massive amount.
    Just use a crock pot on high with some water and a rag in the bottom.
    Heat it to 140 it's good to go.
    When yer done wipe excess off with a moist paper towel and lid the jar put it in tha freezer.
    This glue is 10 months old it's all good.

    This glue dries in 24 hours and can glue a headstock back on like you can't even tell it was broken.

    Squirt some in tha hole or brush it in stuff shavings and scraps in there and tap plug in. Done.

    Might as well stuff some mohagany plugs in those stripped screw holes while I got the glue going.

    Above
    done, letting dry will trim and re drill after cured.

    You can use this glue with a lil tint to fix small finish chipps and to hide plugged screw holes for example from changing tuners in a headstock

    Really thinking that this is a '74 and not '71. Is the SN# a 1XXXXX series? Those caps tell me a lot. EROIIs..wouldn't be found in a '71. I bet that ONE pot is the original. A '73 pot that late would mean a '74 guitar.

    I'd leave the caps myself.

    "I think they stored it in a spittoon."

    Man that sounds really nasty. Glad you came across the advise of Dave.

    Cool project and great write-up! Have you tried playing it yet?
