Nearly done

The Flite 300 is nearly done. Got distracted by the fixies at the co-op....and went over to the dark side (lol). Bought a fixed gear, put new a new chain, bars and a front brake and ...

Re-did my hodgepodge friction shifted Victory/Ultegra/SR drivetrain on my Nuova Strada to a Shimergo 8 speed setup that I had laying around. Pretty fun making Campy Avanti levers work with a HG-51(11-32) cassette mounted on my lovely 600 Tricolor wheelset.

I just picked up this Colnago Master Piu frame and I am going to send it out to be chemically stripped lugs and stays polished and powder coated and clear coated and then it will return. Have several other small projects to finish so I can devote my time to this when it returns

The Serotta is making progress, the dropout faces have had the paint removed then the faces have been stoned to true them up in preparation for spreading the frame to 130mm, aligning the dropouts and verifying the frame is correctly aligned. The goal is to have the headset and bottom bracket installed by Sunday evening.
Now a preview of coming attractions...

The Serotta frame was successfully cold set to 129mm, all dropouts were aligned, frame rear triangle required a minor tweak to bring everything back to square, we have a green light for assembly... WOOT
So next up is a final clean of the seat tube, bottom bracket, and steer tube. Facing of the bottom bracket then fitting of the headset will be the first tasks in the morning.

The dropouts after rework with a 600 grit diamond stone. still a bit of clean up to do...

Today I was sitting puzzled with the scales and hubs. 2 Ultegra 6400 hubs (to represent higher end of the 80's technology), with QR skewers and a generic 7 speed cassette turned out to weigh 885g. Out of curiosity I tossed two cheap Maillard hubs, both with solid axles, and a Suntour 6 speed freewheel. The combo weighs 775g. This exercise is because I'm planning to build another wheelset at some point and the idea is to see how light I can get to with a set of clincher wheels. Haven't figured out the hubs yet, I know I want them to be late 70's and 32 spoke holes each. I would even go for 28H, but finding a reasonable rim for that could be more painful. Anyhow, one idea was to look for Pelissier 2000 and the info I found was that a set weighs 450g with QR skewers. That basic Maillard (and I mean the cheap and cheerful model available everywhere for peanuts, be it with Maillard or Pelissier branding), with solid axles and track nuts, without the freewheel, weighs 455g. So as much as I suspect the 2000 to be of better general quality, I was expecting them to be at least somewhat lighter than an entry level hub. Oh well, thankfully not something that I have to sort out soon...

Last wheel for the time being has been completed. This time Exage HB-RM50 laced onto Mavic MA3. And that means I've used up most of the stock of spokes, nipples, hubs and rims I had and hopefully will manage to clear some space. That was quite a lot of wheel building over the past few weeks, I think I will need some break from it for now.
The rim itself seems fairly reasonable for what it is (an entry level rim) and looks quite alright. Holding it next to Ambrosio 19 Extra Elite I have on one bicycle, it's very similar. Don't know about its durability and read about the spokes pulling through issue back in the day, but all seems fine. I did definitely pay more mind to spokes tension when building this one up and looks quite solid. I'll probably try to find some time tomorrow to take it for a spin. I'm still not entirely sure whether to sell it or get another one in decent condition. Because it seems like MA3 might be actually a reasonable solution for a commuting bike.

Progress on the Serotta... Bottom bracket chased and faced, head tube faced and a corner radius was cut so the headset cups actually sit flat on the tube, it's all about the details... I have changed my mine on the brakes, I'm going with silver 7800 Dura-Ace brakes and not the black set of 9100's shown in a previous post.

More Progress on the Serotta, the seat tube and bottom bracket were cleaned out, gook and minor corrosion were removed, the headset got sorted with two headset washers, so I didn't have to cut the steer tube, yea.
The bars got wrapped and the good news is I did not screw it up. Next up is taking the AlAn apart so I have room to put the Serotta together.

Lug Lining: The final result.
Took a while to find a method that works for me, but I think this is ok.

DecoColor Liquid Gold (extra fine) paint marker with 1 layer of UPol clear#1 over it to stop the solvent varnish from smearing it.




Paint process:
2x etch spray primer
2x white undercoat brush enamel
2x red brush enamel
2x red small metal flake in brush yacht varnish
DecoColor Liquid Gold paint marker (extra fine)
1x UPol clear #1 spray over lug lining
2x brush yacht varnish
That should be fairly well protected - I count 4 layer of 151 Yacht Varnish

I decided to see if I can do something about the amount of play in the rear derailleur (at the mounting bolt). For the time being replaced it with RD-6500 I had around.
It would seem play in the RD-6208 stems from the amount of space between the mounting bolt and aluminium bushing / collar it goes through, as well as probably general tear and wear of the plastic seals in that area. I guess it's something to be expected after 35+ years of use. It's not tragic, but noticeable. Of course, there's no way really to put some shim around the bolt. And no chance for finding a bolt that's just a small fraction of a milimeter thicker (without going through a bin of old derailleurs and trying bolts from each of them). One possible solution could be a very thin washer under the head of the bolt, so I guess at some point I will have to go through the box with old and cheap friction shifters and try to find something. The other option, I thought, might be finding a slightly thicker E-clip to hold the whole mounting bolt assembly a little bit tighter. It appears that hoarding weird parts did pay back. I found an E-clip that's 1.5mm thick, compared to 1.4mm of the original one. I think it actually came from a faulty Sachs/Huret Aris (or was it Rival?). It seems to be keeping the mounting bolt assembly a bit more snug, There is still a tiny little bit of play, but it's definitely an improvement. I guess I will have to look for that very thin washer to put under the mounting bolt head.


RD-6208, mounting bolt assembly parts

And put back together. Old E-clip next to the derailleur.

And some cleaning. I got this set of levers some time ago, but haven't had time to clean it up yet. I was planning to use it for the next project, but it transpired Weinmann Carrera levers are 20g lighter, so I'm going to use those instead. Superbe ones will have to wait for now. I was thinking I should actually polish them, but for now taking them apart and cleaning has to suffice. At least all the gunk was taken care of, perhaps I will make them shinier some other time.


Scratches!

Both brake levers taken apart

AFter cleaning. Slightly better

primer on the Allez Catastrophé

I think I’m supposed to wait a week for the primer before color coat.

any thoughts on that?

The instructions on my can of Rustoleum primer says you can either apply the top coat right away, within one hour, or to wait at least 48 hours. So waiting a week isn't necessary, but it wouldn't hurt anything.

Right! I've used that many times.
This time I thought I'd try whatever Spray.Bike primer is. The website says 20~30 minutes dry time, and doesn't say how long to wait between coats. I've read other stuff on the internets that talked about really long wait times if not baking. So that's why I said I'd be waiting a week. Then another week after color.
I haven't picked up any decals. I'm debating between no decals or possibly some kind of "Shazam" decals, that would make the bike completely un-saleable. With VeloCals gone I have been able to find duplicates of the original Specialized Allez branding. I've used DIYLettering for other stuff. No complaints about them. "SHAZAM!" -- dunno, seems really funny to me.

cheers!

I'm guessing that the drying time would be similar to other spray paints and primers. So probably a week is a bit excessive. WHat I'd say matters more is how much drying time you allow for the main coats and clear. In my limited experience with repainting bicycle frames with 1K spray paints (mostly RustOleum Automotive range) I'd say that the "real" drying time is much, much longer than what it says on the tin. For example, all scuffs I managed to get on one frame I have here now were done within a couple of weeks after repainting. But when I was stripping the paint a year after the previous repaint, it was real pain in the backside to remove. So if I'm ever repainting any bicycle frame again, for sure I will allow lots of time between the coats and as soon as I can touch it it will get stored away somewhere warm and airy and not touched again for months.

As for the pedals, I'm assuming you've tried extensive soaking in some sort of penetrating oil. I had a similar problem with FC-6400 a few years back. I cut the pedal spindles (not fun) because I didn't care about the pedals anyway, and then drilled them out from the crank arms. Starting with a smaller guide hole and then going for progresively wider drill bits. Eventually the spindles budged. There was some cosmetic damage to the crank arms due to my slightly ham fisted treatment of them whilst cutting the spindles, but could be prevented by taking more care. I only tried because I was sceptical about my chances, but it turned out to actually do the trick. The idea was that eventually the structural integrity of the spindle is going to be compromised enough for it to twist, collapse or budge but probably what got it out eventually was the heat from drilling as well. I think I got to 8mm drill bit before I was able to get them out. Most likely you'll have to wave the drill bits goodbye though. YMMV

I placed the cranks pedal down and soaked the non-pedal side with penetrating oil for a week or so. I would once a day or so heat everything up with a heat-gun paint stripper deal.
I also got out the rubber 4lb mallet, and placed the pedal on the work bench, and started wailing on things in a kind of unsafe fashion, trying to get a 15mm wrench and crank arm to move - picture a triangle between the 15mm wrench, crank arm, and bench top, and I'm wailing on the peak of the triangle. Surprised I didn't bust a finger or something. Probably would have if the pedal spindle and finally loosened.... God works in mysterious ways to keep babies, drunks, and selected incompetent bike mechanics from great harm..... I guess being a drunk bike mechanic must give me some kind of double protection! (haha- take that, Satan!) I should really digress.... Let's be careful out on the roads and in the shoppe! Cheers!

After messing up a few things due to impatience I decided to always take the longer route now. On one side, every time I start working on something, I'd like it to work great as soon as possible, but on the other one, I have bicycles to ride, so if I have to wait to solve some problem, so be it. I think it works better than brute force Thankfully, FC-6207 are not exactly rare, so worst case scenario you should be able to find a replacement in a good shape. And the frame certainly looks well made, so it's always a win.
Good luck with re-painting!

You try putting a long pipe on your wrench? A lot easier getting them off with the bike fully assembled.

Wait at least a week between coats or you end up with soft layers under the top layer and the end result will take forever to dry hard if it ever does. Put it in your car parked in the sun between coats. Patience.

Finally got back to this for a few minutes this morning. Mounted the BB, crank, FD, and RD. Now I have to do a final decision on wheels and figure out a better solution for the handlebars. I'd like a bit more drop so I might have to go source another stem.

I'm either going to use a set of Zonda's on this or maybe I'll desticker the Fulcrum Racing One's and use those.


As far as I've gotten right now.

Do you have a digital caliper? Wondering what the tire width measures mounted on the wheel.
