    Well, today I spent all the morning figuring out the parts catalogue is wrong in another couple of places where it numbers the spokes in both front wheel and back. Not a show stopper but again was confusing me.
    It wasn't clear in what direction the spokes face (ie do the outside spokes lean in the direction of rotation of the wheel?)
    I figured the front wheel outer spokes would lean backwards (against rotation to allow for braking) and the rear wheel outer spokes would lean forwards (with rotation to allow for the massive acceleration). This is how the tyre tread patterns are on motorcycles and made sense to me but the drawings don't really confirm that.

    Look closely at part #6 in the rear wheel drawing. It's passing inside other spokes but it's listed as an outer left spoke. On the front wheel drawing the outside spokes are leaning forward in the direction of rotation. So, me being a learner and not really knowing what I'm doing was looking really hard at the drawings to try to figure it out.

    Aha, I know, I'll look at the back wheels in the garage. Obviously the Hardley Movingsons and Chops weren't going to help (little did I know that I should've looked at them as well) but the T140s will:

    Rear wheel from the disc side shows the outer spokes leaning forward.

    This one does too.

    Even the rusty one that needs rebuilding has them facing forwards

    4.jpg

    Bugger me, the one I'm working on has them facing backwards against rotation

    5.jpg

    Well, that's bleedin well annoying :confused:. All of the T140s in the garage, however, on the front wheels have the outer spokes leaning backwards against the rotation. So, I reckon, all is good other than the back wheel on this bike. The rim is a bit rusty and the spokes aren't good either so good job I'm building a new wheel for it.
    I also had a look at the hub I'd be working on as there's 'bruising' showing where the spokes had been positioned. This is looking from the disc brake side

    1.jpg

    So, whatever wheel this had been in had the outer spokes leaning backwards against rotation. FFS maybe that's why it was spare - cause it had crashed due to the wheel being wrongly built. The wheel obviously just ripped apart under the load from the humongous acceleration forces. Poo bears :grinning:
    Fuck it, I'm gonna build it like the tread in the tyre - with the outer spokes leaning in the direction of rotation.

    Just flip to the end if I'm going on a bit and a warning there's going to be tears in the twist at the end of this riveting instalment. :confused:
    By measuring the length of the spokes I labelled them up

    1.jpg

    Sitting the hub with the sprocket side up, insert 10 of the inner spokes in every other hole (I figure inner ones first as they may be harder to get in if the outer ones are already in)

    2.jpg

    Turn the hub over to the disc side and spread out the spokes already in

    3.jpg

    Inspecting the existing wheels in the garage the inner spokes on the disc side are slightly "ahead" of the inner spokes on the sprocket side as the wheel rotates so thread in the remaining 10 inner spokes and position them accordingly

    4.jpg

    The inner spokes run against the wheel rotation or anti clockwise as seen from the disc side so move all the spokes as far as they go in that direction keeping them in pairs

    5.jpg

    Then positioning a couple of wood blocks to keep the rim up and allow some working room lay the rim over the correct way round. In this case the Akront stamps on the sprocket side * later edit* well that's wrong - it should have been on the disc side to match the other bike but no matter now

    7.jpg

    The rim has holes in groups of 4 that point towards a similar spot in the centre. Checking on the other rear wheels the inner spokes connect into the 'first' two holes in the group of 4 looking at them as if they run clockwise

    8.jpg

    The sprocket side inner spoke goes in the 'first' hole and the disc side inner spoke goes into the 'second' hole. Apply some copper grease to the thread (as stainless spokes weld themselves to the nipples apparently) and lightly screw on a nipple to hold in place

    9.jpg

    Work all the way round the rim threading on the nipples in pairs

    31.jpg

    Now move the whole thing to the edge of the workbench to allow the right outer spokes (the shorter ones as the rim needs to be pulled that way away from the sprocket) to be threaded in from below. These go into the 'last' hole of the group of 4. Thread on a nipple as each one goes in all the way round the rim moving the rim as required.

    Turn the whole wheel over on the workbench and thread the left side outer spokes in. Follow the angle of the other side's outer spokes and thread on the nipples all the way round the rim. These go into the 'third' hole in the group of 4.

    33.jpg

    Once they are all in you then have a complete wheel all laced up. Hooray.

    34.jpg

    Here's the twist. In this case there's obviously a problem with sizes. What?!! WTF.
    It's an 18" rim the spokes are the correct length, the hub measures the same as those on the other bikes. :confused:

    Of course, what a bloody tit I am. Knowing where the rim came from (the custom shop down the road) it's off a bloody Harley Whatsitmaface chopper 'aint it. That's what he builds down there. I, wrongly, assumed an 18" 40 holed rim would just fit. Harleys have different hubs. The rim is deeper at the rim centre. It's exactly the bloody same as the one I've got sitting in the chop in front of me in the garage.
    So, I could cut the spokes and thread them to suit but I still don't know if I could make the thing work for the T140 rear. I could try that with the old spokes and see if that works as I've got the hub etc.
    Ok, I give in. I'm gonna buy a new WM3 rim to match the rusty one and use these spokes to replace the existing rusty ones and go with what I know works. Ah well, another tyre to get off and wheel to build. As that wheel is wrongly built it needs doing anyway.

    But, essentially, it's done. I can start the taking apart, powder coating, painting. And the rebuild electrics, brakes etc etc etc. That's that then......:)

    Wow, what a project and puzzle, @Iron. You are a man of persistence, that's for sure! Love the photos. The parts in some of the earlier ones today look like space ships or metal insects.

    I’ve built up one front MTB wheel in the dim and distant... but repaired many front and rears! I totally feel your pain. Well done on your persistence, and elevation to wise village elder!

    ".... elevation to wise village elder"?

    Heck, DCS, Iron passed that stage about eight or nine bike builds ago ...........

    He's currently somewhere between demi and full BIKE BUILDING GOD. In fact, I'm considering writing to what3words and asking that they officially appoint that combination to his home/workshop address.

    @darkman already has ///TRIUMPH.CREATING.MESSIAH :triumph:

    Blimey Gents!
    I'm gonna ask the Admin Staff to read this, I've been tellin' her for ages that the bangs, crashes, loud music and hearty swearing is an artist at work. Then I'm off to lord it over the HOG guys at Riders to tell them about the blue plaque that's about to be positioned at my halls of residence (garage).
    I think I need a new hammer :)
    Cheers Gang......over....

    All coming apart now, so tins to paint.

    8.jpg

    7.jpg

    I was considering getting some gold pinstripe tape and burying it in the lacquer or maybe just brush them on like I usually do. But there's loads of them in the 1966 TT design.

    Then @Tigcraft reminded me (on the XS650 thread) that there's another way. This is the way, put some gold on

    1.jpg

    Mask that up

    2.jpg

    Put some red on

    Move the masking

    4.jpg

    Put some white on

    5.jpg

    Take the mask off

    6.jpg

    Not your usual TT design but I wanted painted mudguards rather than chrome. I'm also gonna paint the side panels rather than black.
    There's a few touch ups and a spot of lettering to do before the clear. Thanks @Tigcraft

    Beautiful, @Iron! It's all coming together. :) Would you mind fixing the paint chip on my Street Glide fender while you're at it?? ;)
