Thanks,
Same guy who did Glynn's Dp, member here called Jonnyb. Though he only does it in his spare time, he also has quite a backlog at the moment, and so isn't taking in any new work for a little while... I guess I got lucky with the time that I asked him.

Sorry, being lame on updates, now I'm up and about mobility wise my wonderfully tolerant good lady is expecting support, help, and chores doing :idiot2:. Shouldn't grumble really, she's been amazing whilst I've tolerated 12 wks of24-7 immobility & pain.
Anyway, today's update is really more of a parts presentation than build update, for the reasons mentioned.
So (hoping the conventional image uploading works well), here's the current consideration for wheels for the build:

NOS Zeds from Rainers. Now, I'm not 100% on these yet, but I'm trying to steer clear from my go-to choice for this build, which would be gen2 Skyway Graphites. Purely because whilst a very nice and natural choice for me (nearly always rode tuffs BITD), I wanted the build to have a predominantly chrome aesthetic, and feel black tuffs would distract from that. So, next choice for me personally is Zeds. But, black again. So, I'm planning to progress with these at present, but may also offer up some chrome/silver rims later. If I ultimately decide on changing it up on the wheel front I'm thinking it would be similarly spec built silver Araya 7X :-\.
Both wheels are going to be built with new DT Swiss Stainless steel spokes, and the as-supplied 12mm nipples are making way for 16mm options.

Up at the front I've located a "never laced" Bullseye:

But, due to the chrome black theme sourced a reproduction chrome-black decal to replace the og red one, don't shoot me.
On the rear I'm going to run a Suntour coaster:

Tyre wise I'm having a little trouble at present. I'm obviously wanting to run freestyle tread pattern, and want black-tan finished period correct examples. But, all I've currently got in stock is later era (late 80's) CompST's. I know some may think this too OCD, but it's not as harsh as "everything on this build has to be 84'" or similar, but within a 2-3 year window, and the ones I have are more like 88' onwards, or around that date frame. So, they'll be ok for now, but I won't be happy that the build's complete until I source something along the lines of earlier ST's (green/blue or yellow/red labels), Panaracer Freestyles, Maximisers, Early label GT freestyle, or something of that ilk, but man it's challenging, I've been scouring eBay & the Museum for months - don't do social media.

The coaster was proving quite a challenge to source. It's not that they're overly rare, more a case of see loads when you don't need them, then when you do want one there's none of suitable condition around.
I was wanting a mint or easily salvageable one, and there just didn't seem to be any around for realistic money. There was one on eBay but the guy was selling it with a random front hub, and wanting 80+ for it. Condition wise it looked fine, but I just didn't want to weigh in to around ?90 when all I wanted was the Suntour.
So, after not seeing anything of certainty for a couple of months I took a plunge on one listed by a US guy on eBay, much better price, but a bit of a risk on whether restoration would be just a good clean, or strip & polish/rechrome requirement:

Thankfully, after stripping it down and giving it a good clean it appeared the 'gamble' had paid off, not massive amounts of rechroming required:

As I've got a nice female axle Bullseye on the front end I want to run the rear with trimmed down axles and Suntour domed axle nuts. So, to start with I'm reassembling the coaster devoid of much grease, just enough to get it together, but appreciating once I mock it up to the F&F I'll be marking off the final 'built' axle length & pulling it back apart to trim said axle to length before final assembly:

And, like Chilli Rinse, I actually get more pleasure sourcing NOS examples of the smaller parts of a build, so was able to reassemble with some lovely NOS Cone Nuts:

Now, the whole 'idea' with the rear hub is a little homage to Woody Itson. I'm not mad enough to spend north of 5K on a beautiful Race Lace Coaster SST setup :idiot2:, so the next best thing for me was to recreate earlier examples. In the Summer 84 edition of Freestylin magazine there's an article where the publication interviews Woody and Buff when reviewing the soon-to-be released Trickstar, and they do bike reviews of Woody and Buff's rides. In that review this is woody's rear hub:

So, first off was to hunt down a pedalPower decal. But as Del's currently offline I had to resort to offer avenues. It actually proved relatively easy in the end, found one with that guy from OZ on the bay selling loads of repo stickers. So, after waiting over 2 months for it to arrive I finally got it in hand and offered it up to the hub, only to realise it was about 30% smaller than the one woddy would have run back in the day. It just didn't fill as much of the hub body as the one pictured above. So, thankfully, it's subsequently been sent off to Steve at esemdesign (good guy actually), who's kindly scaling it up by 39% for me.

Coaster arm wise, well, that was one part of the hub that does need a rechrome, so I'm currently waiting for that to come back, but at least once I get the larger sticker (should be any day now) I'll at least be able to build the wheel.
Reading the above article it became apparent that Woody used std 14g spokes on the rear, but laced the hub race-lace, so I'll be doing likewise, but also fitted small washers to the head of the spokes to provide a wider interface surface area between spoke head and hub flange interface. So, next was to hunt down some suitable washers.
That proved more hassle than needed. 14g spokes are around 2mm in diameter, so I initially just ordered 50 M2 washers. When they arrived they fitted over the spoke body well, but at the head end just didn't sit right. So, next I order 50 more, but M3. When they arrived they fitted the head end fine, but just didn't look right (compared to the original mag image), they look too large at the hab-flange interface. So, take 3, I order 50 M2.5 washers, and thankfully they look about right :crazy2:.
