I will have to say I have to admire someone who treats frame brazing the way most of us treat cone adjustments or parts replacement.

Thanks, I have a set of those in the parts box but they look a bit "barnacle" like I think. Cable guides are a cleaner look in my opinion.
. Besides, who can pass up an opportunity to play with fire and get metal red hot!

While I don't entirely disagree I think they look ok, serve their purpose and provide some on the fly adjustment.

And now that you bring it up, maybe I will paint some to match just to see if it works, maybe.

I am very proud how this bike turned out, and will be posting more photos and details soon. Seeing all these great builds on the C&V forum here has been very inspiring.👍🏼
Love the patina and I bet those brake pads rock.

That's fair, but since I look a bit barnacle myself these days, it's a good fit for my bikes.

I tried enamel paint on some bolt heads and it turned out OKish, though it's not very long lasting. Pretty good on fluting (crank arms and seat post) as these are not things one tends to touch with any tools. So I'm interested in seeing what method you use and what's the result. For my next build I'm thinking about getting some Alu components black anodised (quill stem, shifter levers, hub shells).

Just dropped off those bikes I fixed up at the nonprofit's storage space.

Good news: they got some new kid's bikes donated from a large distributor.

Bad news: "Some settling may occur during shipping & handling."

I have some touch up paint and a spray can of 2 part for frame in question.

Would probably wait and touch up the tool socket after or leave it depending on how it looks.

Finished (for now) the rebuild of a '91 Bottecchia SL, basically just moving most of a Campy group from a donor over to this one.



Wrenching notes ... I moved the Triomphe crankset from its Triomphe bb (114mm BSE) to one a little shorter on the ds for this Italian frame, a symmetrical 116mm Shimano 6400. The chainline is in that reasonable/happy range, but the small ring is pretty close (3mm) to the stay.

Shifting was a little noisy in the stand until I removed a link of donor chain. The chainstays here are almost a half inch shorter than the '87 Falcon donor. From the middle of the dropout here, they're only slightly over 16", preventing the wheel from dismounting with an inflated 23.5mm tire.

But I'm very excited about the shifting on my maiden voyage. I was especially concerned with how the braze-on fd would work out after I had trouble with the same issue with an '84 Pinarello a month ago. Here, I left the old Shimano 6400 fd in place, but removed the labeling. Setup gave me all the adjustment options I needed. It's a joy to shift, sounds great, and doesn't require any unnecessary trimming.

For now, I'll be content with the old (1985) look of the non-aero Triomphe levers paired with the bike's (1991) aero top tube routing ... at least until I find some beautiful Chorus/Athena replacements.

Anyway, it turned out to be a great decision to "upgrade" to a bigger frame, and I'm fortunate no one else had the good taste and forethought to snag a $300 classic Italian that sat all sad and lonely on Craigs for two months. This is the biggest frame I've ever wanted to keep and am very happy I'm just tall enough to make that 6400 aero seatpost work.

More pics in the Bott thread here.

Now working on rebuilding the Falcon. Started off by destroying my poor little plastic under-shell cable guide after realizing the right side cartridge bb threads were just fine -- it just couldn't go in straight due to the tall ass overkill rivet holding the guide in place.



Suggestions? Off to eBay for a replacement, I guess.

This beautiful Red Rocket is from the Wildwood collection.
The Falcon gets my first ride, I put a new saddle the San Marco Concor Light with titanium rails. A slight tilt up on the bars. I still have to fit this for me but that shouldn't take much. Right now this bike has Modolo brakes and levers, Nervar cranks Campy hubs on GP4 tubulars.

Keeping with that of the Union Jack

The Raleigh Competition has gotten it new lease on life. Fork alignment successfully set, front triangle checked seatube checked good down tube and headtube needed (ahem) extra polishing are now spot on, rear triangle was not touched



The Raleigh is in the midddle of a hub and rim swap, the original wheels concave Weinman and Campy GS have broken spokes front and back. The wheels pictured are Mavic Module 3, the rear has Campy GS hub the front has a Shimano Arrow hubs that will be replaced with Campy one I get preferred spokes.

In case someone was wondering what Selle Italia Turbo looks like stripped to its shell, photo below. I had this saddle for a while and the padding and cover were mangled already. So I thought I might as well learn something new and see if I can modify it a bit, get new padding and new cover for it. The idea is to drill some holes along the centre line to make it more flexible, then glue on foam (of camping mat variety, most likely), but thinner than the original one (Turbo saddles have quite a lot of foam). Then sand it down to give it the right shape and cover with PU leather or a piece of suede. There's no particular purpose to this project, though I'm curious to see if I can make it a bit lighter and look nicer. Right now it weighs 275g. It will be a slow project though, I don't particualry need a saddle urgently.

Today's post-ride project was this Sun 3-speed that's been languishing in a half-rebuilt state for a while. I had grandiose plans to do a thorough de-rusting, but the oxides won this round and I just reassembled it into fully functional if not cosmetically perfect shape. Now I just have to decide who gets it, given it's a bit too beat up to sell and too much work to get pretty for a foster kid - so it'll probably go to Rusty Spoke for work trade or perhaps another bike-related nonprofit.



Now I'm getting around to dismantling a 700C wheel with a little teeny issue:

Defanging a chainring

On my Lambert, I have one chainring since I am using a hybrid gearing set up, Sturmey Archer AW + a derailleur. I had two 52 tooth chainrings available in my spare parts stash, so I thought I would turn one of them into a outer ring, pants leg protector.


Before


Almost there


Complete with sanded edges

Sans teeth it is down to only 86 grams now.

There is no such thing like too many freewheels one can have. Especially Suntour ones. And it's also a cautionary tale, so I thought I'll share.
The one in the first photo, with the freewheel body still on the hub shell is what came with a bicycle I got about a year ago. Hub is Maillard, freewheel is Suntour NWN and the rim was Weinmann of the concave variety. Back then I didn't care about the freewheel as much as now and it was stuck and wouldn't come off. The spokes were dreadful and what I really wanted was the rim. If that happened right now, I would deal with the issue in a different way and that that stubborn freewheel off and have the whole deal: hub, freewheel and the rim (not the spokes, these were beyond unusable). Back then my solution was a wire cutter. I got the rim alright and still have it (together with the front one), but as I found out, both rims actually need some rounding before they can be successfully built into something useful. The lesson here: don't be impatient. You might think something is stuck without hope, but there's a good chance a bit of gentle persuasion and time will solve the problem.

The rims ended at the back of the rim cupboard. The hub and freewheel ended up at the bottom of the junk pile. Until recently. I had another Suntour NWN with NOS sprockets (and the body wasn't used much, if ever), but unfortunately only 5 sprockets. So I decided to dig out that hub shell and see if I can get the sprockets off and re-use them. Surprisingly, that stuck freewheel is quite smooth. Must be ages of soaking the darn thing in WD40 did it some good. And the sprockets came off no problem. As a result, I now have another fully functional 6 speed Suntour freewheel I can actually use (second photo). The gearing I'm not sure of yet. It's 13-24. I'm getting used to 13-21 right now and that works pretty well for me, but good to know I have another option available.
I decided I'm going to recover the hub and freewheel body as well when I have a moment. The plan is to remove the outer freehub body and bearing balls, lace the hub into a wheel with inner tube and tyre, soak the freewheel body / hub shell thread with penetrating oil for a few days and get the freewheel body off. Interestingly, I got recently Shimano 6207 hub with the same problem, so I will actually get to try this approach sometime next week.

I have finished the bike and also refurbished the original wheels. 40 spoke Sansin rear and 36 spoke Sansin front. The rims are Arya, the rear is wider than the front. I replaced the original Deerhead derailleurs with Suntour 6 speed Accushift. Now to do some riding.

I bought a 2000 KHS Flite 300 steel frame awhile back. I had to deal with a lot of small rust spots and found some Rust-Oleum that matched the original red paint. I picked up a used Cannondale R300 last week and am using the derailleurs, brakes, and wheels (the rear had broken spokes that I'm having fixed). It's a 97 R300 which had 7 speed downtube shifters. Catalog indicates RX100 8 speed for this year but it has all Exage 7 speed. I want to put the shifters (7 spd indexing Shaimano) on some sort of flat/city bars. Any ideas about adapters out there? I'm also look for new home for the Cannondale frame (small R300 CAD2
Thanks,

For your fork. Heat may help, a clamp or two a board and picnic table or bench. In some fashion the fork sandwich between the board and table clamped could secure things for man handling.

Probably I’ll start with a heat gun this evening.
I stuck a 2 x 4 in the fork blades for some leverage- while standing on the handle bars.
But obviously didn’t want to go gonzo with that bad idea.
I’ll try your suggestion before I apply a torch to the stem. It’s specialized branded. I’d like to use it.

put the bolt back in, slam it to make sure the wedge is loose and up (or down if the bike is right side up). Add your various oils and lubricants and let it seep in, and then pound the stem in (not out- luckily you seem to have a lot of room) FAR easier to pound in than trying to get leverage to pull out. the point is you are now pushing the penetrating oils into the trouble spot. let sit, then pull out!
