    Custom Japanese swingarm bobbins...

    OK....so in my additional 'Mods' thread I promised I would do a little creative machining last week as I was off work....and after decorating the kitchen for my wife I was finally free for a little lathe time..!

    I had intended to make a custom set of Swingarm spools/bobbins for a little while (and I wanted to incorporate a Japanese theme)...

    I like working in brass (my favourite metal) as it allows me to get a little intricate.....

    A strange quirk with the Kawasaki swingarm is that the location points for the spools differ slightly in that one is welded on further inboard that the other (right versus left) and as such this was catered for in the machining process.

    Anyway I trust the step by step photos will convey the story to completion..and this thread quenches your fix.

    They're too nice to use anymore Brian! You really gonna scrape them up with a rear stand?

    Beautiful work and fun watching how it unfolds in the pics.

    Re: Custom Japanese swingarm bobbins...

    Thanks Guys....as always.

    Arash...someone earlier inferred if they rotate.? Well I machined them in such a way that the 'front' section (main spool) rotates independent of the Japanese flag backing plate section.

    This is to help negate the effect of 'galling' on the 'spool' during the lfting process..... (it will rotate as the hook on the stand locates...)

    Having said that in reality I will probably continue to use my rear stand with rubber 'cups' and it will locate either in front or directly behind these bobbins which will be in place simply to fill their respective location points on the underside of the swing arm......and therefore not be used... (although I do have that option...)

    I have a few more little prices yet to machine....so no rest for my little brain just yet.!! LOL.

    Once again thanks you all for your support and very kind comments.

    Brian, what do you use to coat the plastic? It looks like there is a layer of some clear paint or something over the Jap flags?

    Very cool with the flags

    Now make it all out of titanium but in ONE piece (No need to bother with the SHCS)

    Dish and gun drill the head AND then make a tool that mates to the indents so you can install or remove the spool

    No 'coating' Jaco..........that is the acrylic 'polished' with metal polish and a cloth.

    Ok so although these custom made bobbins required a bit of work ....there was just something about them that kinda did not please me.

    I posted them up on another motorcycle forum for 'another opinion'....and although the vast majority were complementary....one member posted what I was already thinking.....and that was they were a little "Kitsch".

    I was never going to be happy having my own thoughts confirmed (despite the work I had invested)....
    So I decided to raise my game and re machine them..!

    This would be MUCH more involved than before...but ..."If a job is worth doing.,it is worth doing right.!"

    I still wanted to carry the Japanese flag theme...but tie in the Kawasaki colours..(easy to say in theory..but very complicated to construct)

    I am much more satisfied with the overall presentation now....and although I needn't cover the entire construction process (Having covered much of it previously) I will cover some of it in the accompanying photos.
