    6mm? disk. The Strom is 5 and the Guzz is 4.5.

    Picked up a couple of planks from the recently demolished Penguin island ferry jetty.
    Will pass them on to a mate who most likely use them in a table 100yr old cast iron balustrade panels.

    Seems the way forward may involve selling bits and pieces.
    Old mate offered me $200 for this I countered with 250.
    Will see.

    Looks like fun Luke............. probably no pain involved at all.
    285 yrs to go on my projects........ so I am told.
    The guy did not take the bits and I have yet to advertise them so garage still loaded.
    Still again somebody wanted to know if it is possible to register the VMX hack.
    OK The Guzzi project inc pics.
    1st the Guzzi wheel came with bearings and seals for a 20mm axle.
    Also the tappers down close to the axle tube so a larger axle would not fit easily.
    I would have preferred a larger diameter but seeing as there is a steel tube keeping each bearing apart and 26mm sleeve is required to fit the dust seals each side.
    Then from an engineering point of view the effect should be one of a larger than 20mm axle especially if the nut pulls the whole shebang tight together.
    So in the spirit of using what is available rather than $165 minimum spend for a piece of 4140 bar to make an axle.
    I have these 2
    Number one is I believe a Honda axle circa 1976/7 complete with nut.
    Most likely quality steel and may even be high tensile.
    Diameter is good the reading was actually 19.95ish mm.
    Fine automotive thread for nut.
    Just a tad long.
    Will look good if the nut is used on the swingarm end.

    20mm 8.8 galv bolt.
    Length is better (shorter).
    Though size is a quarter mm small at 19.70mm (a little loose)
    Fix with locktight type goo?
    [​IMG]
    Probably have to go with the Honda axle.
    Oh and while I considered a double swing arm its not going to happen.
    Want to show the pretty wheel in its best light.

    Have been helping a mate out between mine shuts.
    Here is the frame for a church bell tower he is refurbing.
    Complete with the old white cross to the left and part of the new behind frame.
    The shed is sublet from the guy in the background.
    He sleeps in the run down house but uses the run down shed for his lounge room complete with wood fire.
    Here he is watching his big screen in the area we use for working.
    This is an area that is in the process of being redeveloped for housing quite close to the city.
    Sunrise mine air ticket booked for Monday.
    Oh Luke you would never guess what I found on the lathe in plain view???

    Has potential if a little scruffy.

    Took a while to pilot then drill a 20mm hole 110mm deep.
    Be a couple of weeks before I get back to it.
    Hopefully be able to buy some materials as the bits and pieces are running out now.
    Also need to work out how I want alignment issues to be adjustable at or near the sidecar wheel.
    I am sure there are good reasons for the 'normal' sidecar attachment/adjustabilities.
    But not on mine thanks,

    I have a number of drill bits up to 25mm collected over the years though the pilot/drill bits look useful.
    At 110mm deep and it may have been better (easier) to drill from both sides though I was a little leery of alignment issues.
    Better to keep the piece in the chuck as long as possible so everything is in alignment so to speak.
    The full length of the drill plus part of the shank was just long enough.
    Just took clearing the shank every few seconds for the last bit.
    That is the thinking this end anyway.
    Now an internal cutter is definitely on the books for sure, the set of cutters I got did not include that.
    Hmm $160 at the local (Kewdale) may have to watch Gumtree/Fleabay.

    Her you go Luke the 1st pic is showing the complete (mostly) bike on the right.
    I hope to get it up and running soonish.
    May even find a battery for it this week and give it a kick over.
    (no starter apparently).
    It has most likely new or re chromed fork legs as they look new.


    [​IMG]
    The second is the front end I pulled of the rolling frame.
    Seems straight though dirty and the chrome is not so good.
    Is there a chroming place your way?


    [​IMG]
    What bits do you need? Will have to figure a good fright/freight method.
    Dont think the guard is perfect either.

    [​IMG]

    The third frame had been involved in a sudden stop somewhere along the line and so there was only one bent fork staunchion and the head stem for it was bent as well.

    Just found this site I made a few changes from the 1st to the second pic.

    [​IMG]

    [​IMG]

    As can be seen the but and the seat are not connected. I have in mind a thicker higher seat base.
    Maybe a Russell day long when the funds become available.
    My progress so for toward acceptable ergonomics has involved.

    The bars moved forward and down ( pleased with this)

    And the pegs back and down (Not quite as well executed) May do again

    Many thanks to the one who set this site up. (http://cycle-ergo.com/)


    Now back to the lathe to see if I can set this boring bar up correctly.

    Just add a pad (or different thickness pads) to judge the improvement before spending $$ on a custom seat.

    Good idea!
    I assume you mean something like this?
    [​IMG]
    Actually it decided me on a custom seat and preferably from someone who from what I can tell does it properly.
    The old bony but has to carry much more than it used to with less muscle/padding.
    As an aside with a little too much info sitting on the gel pad for a half hr makes my little mate go numb. :confused

    Experience teaches me I don't have enough experience.
    The height of the tool post dictates the height of the tool holders.
    Which in turn dictates the height of the carbide inserts.

    Me I just measured a tool holder an said right 16mm (5/8") and bought a 16mm boring bar.
    To be fair it was the only one in the shop (in the display cabinet)
    It would seem to me though I don't know, that the cutting bit should contact the inside of the pipe near the horizontal center point?
    Comments?
    Don't all rush me now.
    I raised the tool holder as high in the tool post as possible but it still cuts a few mm below level with the center.
    Ok on larger diameters but probably not for its smaller 20mm potential.
    May have to make an adaptor?
    These sorts of things tend to stump me for a few days.

    Ok some progress.
    Some scruffy bits of pipe & bar with matching turning.

    Did you know this bench was formerly used as a jig to make shelters for the Orangutans at Perth zoo???

    Thanks Luke .
    16mm is the height of the cutting bits for mine.
    My boring bar in the earlier pic has it set lower.
    Mods may well involve judicious use of a 5".
    It is only the bottom that has to stay straight and flat.
    Will measure carefully 1st.

    Actually Luke the stub is going on the other end of the swingarm.
    Now way it would fit the Guzzi wheel.
    Been sitting around for a few years so it's time has arrived.

    On another note I have a nephew who brings things home to his occasionally.
    1st a crane then a truck then this.

    Think the wobbly is an earlier version. Only 5 tonne.
    They were 10t before the end.
    I started in an old 6t single ram.
    We then used an 8t with a winch.
    Both were a serious handful on the road.
    Don' take your eyes off the boom.
    Look at the bonnet (hood) at speed and you find yourself in the wrong lane struggling to get back in control.
    Don't ask how I know this.
    Oh and blow a steering hose while turning and life gets pretty intense.
    They were great machines that changed the industry.
    Made here in WA. Tractor and all.

    The tool tip needs to be on center for best results, and tool life. Plenty of info on the web on how to measure this, the 6” scale between the part and tool tip, adjust the tool height until the scale is vertical, good enough.

    The stock in your pic looks too far out in the chuck for good work. If the lathe doesn’t have a big enough bore then you need a steady rest. If you have neither then you just take light cuts and live with the results.

    Great advise gents.
    Thanking you very kindly.

    I was able to get that part done with relative success if not perfect but OK for now.

    Will modify the holder before next boring session I think.

    Had a scratch around in the cabinet under the lathe and found some stuff I forgot I had.
    Seems if I haven't sighted it in a couple of years I tend to forget about it.
    Sadly that is not a new trait.
    Probably got to much stuff.

    Tinkered with the idea of having the pivot at an angle for a possible steer affect on suspension compression.
    Brian/Bruce/brain started to hurt so settled for simple.

    [​IMG]

    Almost a swingarm with toe in and wheel lean adjustment.

    [​IMG]

    May fit screw/bolt adjusters.
    Hollowed the spindle as a mount point for a sway bay.
    Suspenders? May nick the Fournales of the Suzy.


    Arbor for wisteria.
    Part of the 285yr project plan.
    I love it but might scale the height back as the council will want a say in it.
    Better to fly under the grubbyminters radar.
