    Default Workshop happenings

    The top plate is 3/4" wash ground plate and the other piece is a scrap block of alloy.





    The dowel is coated with red texta. I use it as an edge finder.

    That is the nicest 4 hole, slotted hunk of steel I have seen today

    I never thought of making one myself, but I do have a motor to do in the near future. You are always an inspiration Steve.

    Thanks Eric. Nice to hear from you.
    There are times I think about posting some work I am doing, but once I'm up to work speed and concentration, it's distracting to slow down for pictures.
    You and I have mentioned in the past that the forum needs a shot in the bum.
    Here's a 10 cc of Australian git it dun.



    I had to take a cut off the side for clearance for the lifter block. Maybe another cut at some time in the future. But a miss is a miss.



    Some nice washers to stop the nuts from leaving a burr on the nice new tool. I used a wet stone to take the manufacturing burrs off the bottom edge of the washers.

    Need to machine out the radius in the angle iron to allow it them to sit flat on the plate.







    They sit nice and snug now. I added some pinch bolts on the side.
    Doesn't look like I took pictures of that sequence. I was probably on auto pilot during that stage.
    The angle iron buffer function will become evident in later posts.
    Apollogies for galloping along. I would have liked to have added these shots in a slower progression to give the forum a bit of continued interest.
    But wife is dragging me out of my work shop and making me go on a holiday in two days.
    My protestations of : (Honestly, I'm relaxed here. I like my workshop)... didn't work.
    She's dragging me onto a 12 meter catamaran to sail around the Whitsunday islands for two weeks.
    I'll post the rest of the job tomorrow.

    So I expect you're getting up at 4 am, slurping coffee, and keyboarding this thread (while she sleeps?), so's we don't die of suspense wondering what the heck?.....
    I love fixtures, and tooling up. (this should be in custom tools thread?) It has always seemed so archaic to have extra hands on standby for landing cylinders while the blind guy with arthritic fingers did the lost-and-found thing with the keepers.
    May I presume that the plate/clamps are for steadying the rods while the hovering cylinder/piston heads for home?
    This after tweaking the rods?
    More, more, now, now!

    Looks like a copy of the HD fixtures for straightening con-rods to me

    Thanks guys.
    Fitment to front cylinder deck. Check!



    Machined a pocket in the middle of the plate to allow the hole of the little end bush to come down level with the plate.
    The front cylinder checked out good. The rear cylinder... not so good. 019" out.



    I needed a better - professional tool than I have been using over the years. To date, my conrod alignment tool has been a 2' shifter.

    Milled the edges of the piece of scrap alloy to square it up.





    Then cut it in half.

    Ran the mill over the pair to match them up. And then clamped them on top of each other to drill and tap them together.





    Once that was done it needed a slot cut all the way through.



    And a hole in the end

    Needed a handle so I used a bit of 1 3/16 alloy round bar.



    Test run on a 46 FL Knuckle fly worked perfect. The story behind these flywheels, I bought a 1946 Knuckle bottom end thinking it was just original.
    The rods had been polished, it had lightning gears and a 36 cam shaft. I guess it was someones hot rod back in the day. Any way. My tool worked good on the sacrificial rod.



    Hi Thomo.
    I didn't know H.D made a tool tool like this. I've seen a rod holding tool in the service book, which stops the flywheels from rotating.
    I've also seen the tool that slides into the wrist pin bush to straighten rods.
    I didnt like the idea of the wrist pin tool.
    The angle iron parts of my jig are used to wedge hard against the rod before trying to bend them. This takes the load off the flywheel and stops any misalignment. After correcting the rear rod of my engine, I put a dial indicator on the end of my pinion shaft. It has a run out of 001" so I am happy to call the tool a success.
    I look forward to reading the work of someone else.
    Message to the Mod Squad, please push some buttons and throw some switches and move this thread to "Custom tools". Appologies.
    Gotta go pack my bag
    Regards Steve
