Just a suggestion.

Thanks, DD. Not sure why I just assumed everyone uses enamels for paintfill... Shopping list has been updated. Do you hit the paint with Goof-Off once cured or before?

Yes, I use oil based enamel. I think it adheres better and is more durable. Yes it takes much longer to dry but I have the time. I've had good luck with modeling (e.g. Testors) enamel though that's not as durable as the 'real' stuff like tractor and equipment enamel but there sure are more colors. I'm going to line the lugs on my Frankenbike with Testors enamel. Real easy to wipe away if I slobber it but I have the right brush so it should go OK.

I let it cure at least overnight these days, but I've allowed it to dry for a couple hours and then removed the excess back in the past. Seems to work fine either way - I'm just lazy these days :)

I Thanks for the paint tips P & DD.

This evening was spent toying around with hub/axle spacing - I think I've got things just about where I need them. Close enough until the wheels are built and I can install the freewheel at least. The rear DOs are spaced at ~120.08mm where it counts, the hub below (eBay find, not the hub that came with the bike) was originally spaced at ~127mm. The dropouts are thick enough that I wound up reusing the axle, replacing the 10mm spacer for a 4mm and adding a 1.5mm washer. Nice and simple. I plan to use a Regina CX-S Ultra 6 freewheel @pastorbobnlnh rebuilt a year or two ago. I am casually searching eBay for 5 speeds as well - just in case... (drop a line if you have one you can part with, Itl. thread)

Parts still need to be cleaned and polished. Hub flanges will get black paintfill.

http://i.imgur.com/ZSda1lG.jpg?1

The space from the FW thread stop/shoulder on the hub body to the outside face of the locknut measures at 29.71mm. I can squeeze in another 2mm spacer if needed, but things may be good as-is due to the shape of the dropouts. The freewheel measures 27.8mm at the widest measurement. The portion of the freewheel body that extends over the hub body (i.e. past the threads toward the centerline of the bike) is somewhere around 1.5-2.5mm depending on how I measure it. That may be enough to give the (9 speed) chain some breathing room to the DO (i.e. there should be a gap of ~3.9-5.4mm between the outside face of the freewheel and inside face of the dropout). Small sprocket is 13t. I haven't tried to estimate the chainline yet, but should.

http://i.imgur.com/CLwFw9U.jpg?1

The longer (i.e. meant for 126ish spacing) axle measures at 134.3mm, leaving 6.5mm exposed beyond the locknuts vs. the 7.5mm dropout thickness.

http://i.imgur.com/4xbU3Kw.jpg?1

The rear hub is 32h, I'm looking for a 32h low flange front to mirror the wheelset that came on the bike - I like the touch of high flange rear, low flange front. A set of 32h GP 4 rims might get built first - there's also a set of 36h Arc en Ciel that I'd love to trade for a set in 32h (black) and use may get used instead.

http://i.imgur.com/NGeX4aN.jpg?1

http://i.imgur.com/YTNM4Q4.jpg?1

EDIT: Looks like the Arc en Ciel only came in 36h drilling for road, explaining why 32h was so tough to find... The track spec'd rims are lighter than I want to go at 310g. Still, according to velobase, 36h for Arc en Ciels are lighter than 32h GP 4s by 0.22lb. I'll weight them tomorrow. I really like the Arc en Ciels, decals on their way. The Arc en Ciels may build into a stronger wheel without much of a weight penalty over the GP 4s using modern swaged/DB spokes. The weight penalty will be closer to the hub anyways considering the lighter rims. I have a few more 4mm Campy axle spacers, and the wheelset that came on the bike has threads showing, so I could always build the AeC's for every-day riding, and re-space the original 28h wheels (which were built at 127+mm) with new spokes and a 5sp freewheel for weight weenie-ism. Decisions decisions...

Sir_Name 10-02-15 08:32 PM

Front der. also arrived today - it may get switched for pre-CPSC if I find the right deal before I get too far (crank arms are '80).

This should be interesting - clamp diameter is designed for 1.126", the seat tube measures at 1.25". Check out the modification to the original(?) Cyclone to accept the larger ST - a link was added between the two halves of the band clamp to spread the diameter:

http://i.imgur.com/T3uH1aL.jpg?1

http://i.imgur.com/gD1JQ26.jpg?1

http://i.imgur.com/OAUDNWZ.jpg?1

http://i.imgur.com/rxUb5nn.jpg?1

In order to get a Campy FD in place, the first idea is to do a slight amount of bending and some file work to convince the FD clamp to work with the thicker seat tube. The second idea is to work with someone who has the tooling and expertise to fabricate an extra link similar to the Cyclone above. The second option is a bit more complicated for the Campy than it is for the Cyclone due to the location of the band clamp pivot with respect to the derailleur body.

http://i.imgur.com/TPnxi7B.jpg?1

http://i.imgur.com/wi8GlBm.jpg?1

The only way I can see to add a link to the Campy. derailleur would be to (destructively) remove the front face of the band clamp, remove the pin, then install a new front face plus extra link with a new pin. Beyond my equipment. Either way, I hope to find a few junked derailleurs I can experiment with first. Cyclone may go on in the meantime.

Any other ideas? Of course, I could stick with the SunTour....

Sir_Name 10-28-15 10:36 AM

http://i.imgur.com/FO54P1o.jpg?2 http://i.imgur.com/wauA5I7.jpg?2

Slow going. I've got most of the parts together at this point, just need to make the time to freshen everything up and then build it up. Still need spokes, tires, front Record hub, and a close-to-NOS 42t inner Campy ring. Let me know if you can help with that last item...

I'll be building two wheelsets for this bike, mostly because that's just how things worked out. Both will be built with Arc en Ciel rims, one 36h set in black anodized laced to Weyless hubs (thanks rhm), one set polished Al to 32h Record hubs (high rear, low front). At some point I'll also re-space/re-dish the 126mm 28h rear that came with the bike to 120mm spacing (the frame was spread to fit the larger OLD when purchased, I'd rather not do that).

RobE30 10-28-15 06:26 PM

I'll go check my boxes for a NR inner ring

RobE30 10-28-15 07:28 PM

I have a 42 and 45 inner ring, unfortunately they both have tooth wear but are still presentable. Let me know

Sir_Name 12-18-15 08:44 PM

Welp, update time.

Drillium Dude helped out with a few items which got my arse in gear on a bit of cleaning and assembly. Most of the other parts are good to go or need just a bit of detail work. Black paintfill on the chainrings and high flange hub is next - I already hit the flutes on the seatpost but need to clean up the overflow.

http://i.imgur.com/zCxPMrh.jpg

http://i.imgur.com/xplDJT6.jpg?1 http://i.imgur.com/WtPwvoQ.jpg?1

Getting the wheelset together is the final big project. And selecting tires. Things kinda worked out (i.e. I went overboard) and I'll end up with a ~heavy duty set of wheels for everyday use and another lighter set for special occasions.

The everyday set will be black anodized 36h Arc en Ciels front and rear laced to weyless hubs. Those'll have the fattest tires I can fit, looks like 27-28mm. I need to come to a decision on the light use set...I'm thinking 32h polished AeC to high flange Recod hub rear and 28h Performance rim to low flange Record front. Tires will be 25mm max. Double butted spokes for both sets, not quite sure on gauge/mfr. yet. An ultra-6 Regina CX-S will probably go on the 36h wheelset, with a 5sp of equal gear range on the lightweight set.

The one holdup with the lightweight set is that the finish on those two rims doesn't match (at least not on the examples I have). That'd bother me. Assuming it's possible, I'd consider stripping the anodizing from the Performance rim and polishing the Aluminum to match the AeC rear (though I doubt that the polished AeC doesn't have some sort of clear anodizing or finish for it to still be looking this neat). That sounds like quite the project (esp. at the eyelets), but this wheelset won't see much use, so at least time isn't much of a consideration there. I'm not a huge fan of permanently altering the otherwise ~fresh Performance rim, especially since that'd mean separating the matched set. Not sure yet.

http://i.imgur.com/EgVbNg1.jpg?1

The Performance rims arrived today - the packaging could've been a bit more robust... :twitchy:

http://i.imgur.com/2cCXDfT.jpg?1 http://i.imgur.com/LbIH0lT.jpg?1

Both rims are flat enough, but it's tough to tell if they were ovalized on their trip to me. There's no immediately apparent damage at least. Tomorrow I'll cut a length of cardboard to match the ID of the rims to check how consistent the ID is at each eyelet.

Drillium Dude 01-27-16 04:34 PM

Well, I missed out on the most recent addition to this thread. Lookin' good (and I'm not just saying that because there are some parts on there I had a hand in, either). How are the wheels coming along?

I also don't know if I missed it the first time, but neat gear cable guides at the headtube. Looking forward to new pics of the black infill on the post and rings.

Ah, thanks guys! Yes, I stalled a bit...busy with work and a long commute. Hopefully that'll change soon with a possible position in the industry... :)

Paintfill on the post is complete, but I think I'll redo it due to some runs in the paint (was messing around with thinning it out to smooth into the contours more quickly and evenly). Still need to add some fill on the excellent drillium (can't overstate how pleased I am with that bit of work! Thanks yet again DD.) - I'm thinking black fill on the inside surfaces of the factory cutouts in the chainrings, leave the drillium on the rings alone for the bling in the sun. Same on the FD clamp.

Wheels are almost set, I think I've decided on spokes, but want to re-read some material and watch some new-to-me wheelbuilding DVDs before I fully commit and start the build.

The front Weyless hub is a little tight, too. Not sure if that'll loosen up with use or if it needs a rebuild (not easy I'm guessing). Might wait until it's built to decide on that.

Other than that...tires are still needed. An some dry, salt-free roads. This served as a kick in the pants to get moving on this again...!

http://i.imgur.com/rMO0zgU.jpg?2
(thanks again for the hubs, R. They're perfect for the build IMO and polished up beautifully)

Not period correct, might use it anyways:

I had this set of red anodized RINO chainrings- I was trying to find someone to trade with me. I ended up stripping the red anodizing. :(

Ha, you know, I remember seeing those when you were looking for a swap and thinking "those are interesting, but what would I use them for?" Oops. Pretty sure that was before the pictured rings were even a thought (and I wanted to keep the Sugino rings that were on the bike when I found it).

Neat crank arms and rings, I esp. like the Avocet. Really cool stuff.

I'd hold them against one another, compare their diameters at that spot. Then rotate one a bit, check again... repeat. Turn one over, check again. If you don't find obvious flat spots, you're probably good to go.

Good idea, thanks. Much better than my original thought. To take it a step further, might as well confirm radial true of a built wheel and compare both against that. Guessing the light packaging was a result of my offering 'full price, seller pays shipping' on the BIN/OBO auction...lesson learned.

Thank you very much! The Stronglight looks "right" on the 70s bicycle- something about it just didn't completely click for me on the 80s bicycle with the 80s/90s parts. I went back and forth, but it's currently wearing the Avocet. BTW- those were made by Ofmega- and are apparently the same as the Ofmega touring cranks.

Huh, the more you know...* Thanks for the kind words on the Klein, I feel fortunate to have found it. Pretty bikes of yours above. I have one touring frame that I love but has some significant damage to the DS chainstay (Pro Tour 15). Some day I need to have it repaired or admit defeat. Hopefully the former.

I have a soft spot for Kleins, I remember seeing my first one, in print, a copy of Bicycling magazine, in 1978. This one is going to be righteous, Sir_Name. Your diligence in finding the right parts for the bike are commendable. Enjoy riding this beautiful bicycle, well done, sir, very well done.

Bill

This is going to be gorgeous when it's done.
