She's finally arrived - Changa Build
Picklez:
After that I ran the third (imperial) die up the spindle relatively gently. But, when it reached the non-threaded part it soon became clear it probably wasn't going to easily cut a new thread in the wider diameter section.
So, I'd needed a way of reducing the diameter slightly. Unsurprisingly I didn't have a lathe in my back pocket.
Not deterred I cobble a very pour mans version together:

I know, a bit outrageous but worth a try.
Well, after a bit of trial and error it looked like I might be in luck.

Admittedly not a perfect result, but maybe just enough. So, back to the die, and this time 'success'

So, happy with the outcome I just repeated the effort on the spare og shaft I had. Here's the result, after completing the same process and after 'restoring' and polishing the spindle too:

So, now just time to strip the rear calliper down and swap out the spindles:

Then, wanting to keep the rear finished length as low profile as possible I wanted to see if I could find a nice little spacer that I could use rather than the conventional idea of using two interlocking half moon washers. Here eBay came up trumps:

So, calliper with the replacement spindle fitted, and then finally mounted up:

Much happier, though I've now realised I should have also cleaned the unlock nut up as well when I polished the second og spindle. I know I'll be doing that in the next day or two. OCD :idiot2:
Ok, that's all for the moment.
Cheers guys.

This is one hell of a build "wantit" "wantit"

Another pedantic little update.
Tonight I revisit the front wheel. On completion I wanted to do something a little cleaner around the male allen headed bolt area.
[ Attachment: You are not allowed to view attachments ]
Rather than the black bolt and flat washer I was thinking, polished bolts and silver load spread type washers, so off to eBay, and today the candidates arrived:

for reference, the bolts are imperial, 3/8 by 26TPI, or 3/8 UNF in old english money.
The only issue is the load washer. Nearest metric size to 3/8 is M10, but unfortunately these load washers are only available up to M8 from places like eBay etc.
Not to worry. A bit of googling and it works out that an M8 cap head has a diameter range of between 13odd and 14odd mm, and a 3/8th cap head is between 14odd and 16odd mm. And main shaft wise M8 is obviously 8mm and 3/8th is about 9.5mm. So, considering a M8 washer the clearance hole is around 8.5mm.
So, I ordered the M8's knowing I'd most probably have a bit of 'fettling' on my hands, and of course when offering them up that proved to be the case:

No problem, using a 9.5mm drill bit easily sorted the centre whole of the washer out, then it was down to the cap head end. That would be easy with access to a mill, but like with the lathe that's not something I have :(. So, home brew time again:

And it worked quite well, about 5-10minutes on each washer & hey-presto (left 'before', right 'after'):
[ Attachment: You are not allowed to view attachments ]
and then fitted, which I'm much happier with:

[ Attachment: You are not allowed to view attachments ]
I may yet de-anodise and polish the load-spread washers, not sure at present :-\.
Anyway, the og bolts & washers, saved for any potential future owner if/when the wheels ever get moved on :daumenhoch:.

That's all for tonight guys.
Thanks for the continued (appreciated) comments & feedback.
