  1. Love a good morry, and yep keeping it sv is great idea as they've all had swaps...

    On my old sedan I installed a brake lamp behind the rear boot emblem. A sympathetic mod to stop numpties driving up my arse, though ironically enough I ended up using a bloke in front of me to stop after some serious brake fade down a long Dunedin hill...

  2. ^

    So figured out why my results were slightly skewed... :-D

    Repeated the test but did it in reverse. Set wrench then positioned weight/s along shaft until it just clicked, and measured the distance.

    Then maths (adding 0.8 kg to account for weight of toolbar) and looks like we're good to go, the numbers line up well from 15 - 90 ft-lbs. With my nerd on I get an average error of 1.0207% over that range.

    Quite an interesting exercise really...

  3. In between paint coats I thought I'd check out my torque wrenches before reassembly (both Sidchrome clickers, one newer than the other). Last time I used the newer one I could have easily boogered a thread but I realised it was WAY out of spec doing it up (just didn't feel right) so I backed off and borrowed another tool. Then I picked up an older one (long story, but basically me taking stuff as part reparation from a loser who owed money) and thought I'd compare them to get some confidence in my tools...

    lbgijv5f.cij.jpg

    Testing these together the older one clicked at much less effort, so something was wrong, I thought mine may have siezed up through lack of use, but couldn't see any way to get it apart without drilling out the rivet, then I realised I had lent it out, and that someone may have overwound the setting dial. Sure enough, turning it as high as it would go, and keeping going resulted in a click as it overwound. I did this twice and tested it again - felt much better...

    So calibration - I asked at our depot (where the proper workers live) but they send theirs out, so looked into doing it myself. Basically did maths to see what the torque relation was to weight applied at a certain distance from the socket... :study:

    • Torque = force applied x distance of lever arm
    • 1 kilogram-force metre = 9.80665 N·m (actually easier to work on kg-cm)
    • Calculate for Newton metres then convert to foot pounds

    So with a handy dandy excel chart and some test weights I marked distances on some tape and set to, basically hanging 10kg, 20kg and 30kg weights at certain points to see where it operated. It was still out on the first try so overwound it another click, and it went bloody well at the 10kg settings (15, 18, 20 ft-lbs were right on the button). Changing to 20kg it was correct at 30 and 40 ft-lbs, but seemed out any higher, but at 30kg it was spot on at 60 and 90 ft-lbs.

    So a little confused but much happier. Initially (doing some reverse maths) it was operating around 1.5 times the setting so seems some ham-fisted lunk overwound it when returning to zero, not once, but 3 times over.

    (lending tools - Gah)... :scratch:

    I'll redo the tests with both wrenches as I'm not sure why some readings seem out, could just be the vagaries of hanging weights along the shaft (or my dodgy maths). Ideally, hanging a known weight from the middle of the handle should coincide with the expected setting, it seemed ok across a fairly wide range though and if I get some consensus between the 2 tools I should be pretty much right...

  4. So busy day yesterday, got a bit more painting done.

    I looked at getting the brake booster out, but from memory these are a bastard to get at, so painted it in situ...

    lnybmwrt.nnq.jpg

    Came out pretty well, not perfect, but far better than it was, I'll paint the master cyl cover grey when I do the grille surround...
    2seggnl3.x2l.jpg

    And got lots of fiddly bits done...
    ntofi3jk.osa.jpg

    And the front end looks pretty good with the masking removed (did this at 5:30 this morning, visions of overspray on the guards were keeping me awake)... :)

    ezowcohb.4vz.jpg

    And it'll be nice to put this together when the paint has hardened a bit...

    Quite pleased with the durepox finish, although I have no idea how it'll last - should be ok under the bonnet as it won't be exposed to UV, although I expect I'll scratch it to buggery lifting the engine back in... :-D

  5. Been putting some hrs in commissioning at work so not a lot of progress, but today I was home and weather was great so I stripped a lot of the front grille area parts. These have suffered many years of exposure to the elements plus the odd immersion in rusty radiator water...

    Sanded the bits attached to the car, and began masking...
    l2jhalq0.nwq.jpg

     

    And laid down some epoxy, looks much better already...

    Also got a lot of little bits painted, will try to get another couple of coats on tomorrow...

  6. Oh and I picked up the headlight buckets. I grabbed these off the Bay as they were cheap enough for a punt (came to around $35 delivered). Donated from a F100 of unknown vintage (picking mid 70s) and arrived 90% blasted clean and very sound...

    And just needed a slight mod to fit, cut a shaped slot, tapped in a recess with a punch and drilled it for spring attachment...

    and ready for paint...

    They will sit around 5mm further out than the originals but that won't be noticable, and I quite like the thought of these things travelling from Robinson, Crawford County, Illinois (pop. 7000) to Invergumboot (pop. slightly more) to be used again... :)

  7. Too buggered to do much today, plus had surf to city with the kids. But did give the shed a real good tidy up this morning as it was a tip. Tools, rags, oil and rubbish everywhere (a consequence of fitting in bits of work when I get the chance). Floor is now spotless, makes it easier to find bits when you drop 'em...

    3hdoy1co.gyv.jpg

    And put all my painting stuff in a surplus packing crate I scored from work. One of my best purchases was a bulk load of measuring cups, about 20c each and really make mixing ratios easier...

    5a2waqzd.rje.jpg

    And pulled some more bits off the front and waterblasted some crud off in prep for painting...

    pr5m5v2s.jsf.jpg

    And tidied up the timing cover. I was concerned about the state of the water passages, but they cleaned up ok...

    53aaljkg.jrx.jpg

    So now just gotta paint random bits etc while I'm waiting for parts to arrive, so's can begin the fun stage...

  8. Being time-poor (as well as poor-poor) I was up at sparrows this am getting some time in. Was dark and almost frosty when I started but was rewarded with this about an hr into it...

    Made up a harmonic balancer puller (the benefit of welding on cold mornings is you get nice warm hands, wifey wasn't so pleased with me using a cut-off disc at 6am) Just a simple pulling bar pressing against the partly threaded in main bolt. I used heat gun on balancer and a lot of grease but had fears my main bolt was a bit girly...
    hqzgqiru.ljf.jpg

     

    It was, stripped out almost immediately so upped the ante a little...
    05docevi.01h.jpg

     

    And great success...
    g0ol0m2t.slu.jpg

     

    Timing cover off and the chain seemed really loose, but was still within spec, go figure...
    mt0qwvjn.ma3.jpg

     

    And ready to slide the old cam out...
    cqpsucxj.c1j.jpg

     

    Might try to mask off and paint the block today if I get the chance. Nice to make some progress by 8am...  :)
