That's all for today guys, they'll be a small instalment update in the next couple of days (maybe two or three over the next wk or so), and then a little wait for the blooming pedalPower decal to arrive before I can get on with the rear wheel.
Stay safe, and as always thanks for taking a look :radbmxsmilie:.
bobafett:
That wheel looks spot on mate fistblump 8)
Mikku:
Yep, perfect! :bow:
Picklez:
Thanks guys.
Also, a things of points I forgot to mention:
1. It's the first rim I've built without any herbal support (blinking look down). And what did I observe from that. Well firstly, the build process itself wasn't as enjoyable, but secondly, the satisfaction when looking at the rim as you finish tensioning the last couple of spokes was just as enjoyable as ever, and thirdly ... it's the truest wheel I've ever built - make from that what you will ::).
2. and I really should have mentioned this (in the true spirit of this thread). I've made quite a few points throughout the course of the thread of getting some of the parts for this build at sensible prices, mainly because I picked quite a few of those parts up over years gone by.
Well, karma and all that life balance stuff came to pay me back with the front hub of the build. I knew I wanted a female threaded axle on the front end if I was going with spokes, so that brought it down to a couple of obvious choices, either Phil's or Bullseye's. But I didn't want to get rimmed for ?300-?500 for a pair, especially as I'd be hunting down a Suntour coaster for the rear. Then good luck seemed to strike, a good condition used Faded red 36hole Bullseye on the museum for something like $90 before shipping and the darn tax man. Missing the main axle shaft and bolts. But hey hoy not bad, and I thought i could get a replacement axle from the bay or similar. At the time there was those 'rebuild' kits for something like $100 for front and rear. So, a deal was struck for the hub, and it was on its way to me. On the same day (for a different project) I also bought a set of flights from a member on the museum. Both members posted each item USPS Priority within a day of each other. Well the flights arrived fine, but after a further 4 weeks no sign of the hub, and I was starting to get a little nervous. Then 5 weeks, and 6 weeks, and nothing. I looked into contacting USPS and unfortunately with international shipments you have to ask the sender to contact them. In the meantime I'd contacted the supplier of those rebuild kits, to see if by chance they'd consider splitting a set and selling me just the front axle. Understandably they weren't interested in doing that. So, watching the exchange rate I was gambling for a good rate before pulling the trigger on investing another $100. Then, overnight, the seller pulled the listing, feck. Anyway, about a week later a front 32 hole candidate, complete with the needed axle turned up on eBay, for somewhere around ?80. Nervously watching, 7 days later I pulled the trigger and landed it. So, tax man aside I was in around ?180 for the hub. Gulb, but given todays prices I could just about justify it to myself, and I knew it would be worth it, when restored and the wheel was finally built.
Fast forward to the 6 weeks later point in time, and the blooming hub not showing up. At this stage I'm losing faith. But, given the amount of trading I've been doing back and forth over the pond over the last couple of years it was only a law-of-averages thing. Word of note for all when buying-selling over seas, the insurance CAN be a savour. The only other time I've had anything 'lost' was a set of mint gen 4 Graphite Tuffs. I sold them to a great member on the museum, a real standup guy, but blinking UPS lost them in one of their hubs. Had a hell of a time getting it sorted, but thank goodness I bent over backwards and fully insured them. As I was eventually (after about 6 wks) able to get the buyer all of his money back and my shipping/insurance costs.
So anyway, the hub, I wrote it off as a bad luck story. I'd only taken out basic shipping insurance but at least I'd be able to get about $50 back. So, I now had one useless 32h hub, one lost faded red 36 hole, and still nothing for the build. So, partly in desperation, I went again. A really nice silver ft and rr 36hole set showed up on the Bay, the ones that provide the front that I've finally used for this build, and after a 7 day wait, tracking the listing, I finally got them for the original listing price, which, for anyone just buying one pair of Bullseyes was a relatively ok price given what the last few pairs have gone for in the past few weeks, but for me emptied my pockets of a further ?239.
So, moral of the story, you can always read peoples threads, and think, lucky so and so, when they go on about "picked this up for a good price..." etc., but in the long run the scales always usually balance out.
As for me, I'm well happy with how the build's coming together, I'm extremely lucky that I had the funds to spend, and spent them fully conscious of whether or not I could actually afford to, but yes, I'm in to this blooming front hub for somewhere north of ?400 :crazy2: :shocked: :uglystupid2:
And the part I could only laugh at, otherwise I'd have cried, The faded red hub turned up last week :10_2_12:
So now I have a selection of spare Bullseye's:

But basically, in the long run, I'll build up a mismatched mint silver 36 hole set and move them on, so should recoup my outlay eventually.
You've got to laugh at this game, it's the only thing that will keep you sane.

So another little update.
The rear brake had been bugging me since I fitted it, specifically the amount of spindle showing on the rear of the brake bridge:
[ Attachment: You are not allowed to view attachments ]
Just an issue with the standard length of the rear spindle coupled with a flat brake bridge. None the less something I didn't want to live with.
So, I hatched a plan to strip the calliper down and run a die up the full length of the spindle, and then cut it down to a much shorter length. Now, not wanting to permanently alter the standard finish of the og spindle on a NOS calliper I thought I'd trail this out on a repo spindle first. Then, if it proved out ok I'd repeat the effort on an old og one I had laying around, which I'd restore to good condition at the same time.
So, first things first, work out what thread size these spindles are finished with and buy a suitable die. After quite a bit of looking around I wasn't having a whole heap of luck, but some selling sites were pushing me towards concluding it was M6x1.0mm.
So, (first mistake) I took the plunge and bought a cheap tap and die set that included a M6x1 die. Now, if you look at these spindles they do have a little issue that means running a die up the full length may be a bit challenging. Namely the lower end of the spindle that isn't threaded normally is actually a little wider in diameter than the threaded section:
[ Attachment: You are not allowed to view attachments ]
But, I thought that with a bit of 'power' I'd probably be ok and would ultimately be able to cut the thread I was wanting, that was my second mistake.
We'll the die arrived, and after a little cautious trial it looked like the thread was indeed M6x1, as the die threaded on to the spindle with little resistance. So on we go, all started well, and as it reached the end of the normal threaded section it started to cut a new thread, great. But after about one extra turn things started to go wrong. Basically I continued to turn the die but it just kept spinning at the same point on the spindle without cutting any additional thread, i.e. it started to just spin round and round at the point where the shaft broadened. Worse still, the die was stuck there, I couldn't even unscrew it back off:
[ Attachment: You are not allowed to view attachments ]
Not deterred I thought, it's ok, I'll buy a better quality die, cut the first die off of the spindle, then go gently with the new one, and if it starts to give the same problem would stop and back it off before 'losing' a second die, and work out whether I could get over the increased diameter in the non-threaded section of the spindle some other way.
So, order die #2, and one that was of much better quality.
Well, that finally arrived and I got all excited again. But on offering that one up to the threaded section of the spindle it soon became obvious that the thread isn't actually M6x1, as after literally 2-3 turns of the new die it started to 'lock up'. So, much sole searching and a little pause.
Then after picking up a 'thread finder' and checking my considerations were confirmed. The thread is imperial, actually 1/4" by 26TPI, damn near to M6x1 but minutely different.
So, outlay for die number 3. That arrived, and as soon as I offered it up it was obvious that it was indeed the correct thread size, as it ran up and down the threaded section with no resistance at all.
So, job number one, cut the stuck M6x1 die off of the repo shaft, check that the threaded area under the stuck die would actually still be usable and then go again:

After a little patience with the dremmel type tool one metric die removed:
