Any pics of "guzzied up" 70's NR FDs and RDs out there I can look at??
I've been stuck for a while now with what to decide to do with the NR derailleurs (especially the FD) I got with my latest project bike from 1972.
I keep looking at these 1st gen NR derailleurs that came with it and they just look very crude with their kinda lumpy castings and their very dull anozised finish. Frankly, they look like pot metal items to me and not what you'd expexct from Campagnolo. Would it be blasphemouse to remove the clear anodizing on them and polish them up to a smoother or maybe even mirror finish, or would that look tacky. Might refinishing these components have been a common thing to do back in the 70's. I just never realize how inferior the finishes on these would be compared to what I have been used to expect for Campy stuff from the 80's.
Maybe if some here can post up pics of NR componentes that they have polished up, I can make that decision to do so easier with the inspiration they could provide (just a link to a pic library you might have will be great too!).
Another solution might be for me to just mount on later NR derailleurs from the 80's instead.....anyway, NR's NR....right?...but then the original derailleurs will never forgive me for separating them from the 40 year old bike!....drat!

You can definitely polish them and I don't think they are anodized if I am remembering correctly. It can be a bit hard to get into all the nooks and crannies without disassembling the bodies (which I probably wouldn't do as they are held together with pins). I think the "crudity" of their appearance is a part of their attraction. They are more interesting in some ways. Look at any of the pics on my website (in sig), I usually have one closeup of the rear derailleur and they will include polished and painted NR rear derailleurs.
Here is one in particular:

They are both anodized and they'll clean up well - however, as BlueDevil63 points out, you'll have the devil of a time getting to every nook and cranny without disassembling the works. You may not want to in the case of the RD - just ask rootboy
This can be done on the RD, however - see below - but you'll still have some areas you're just not really going to be able to get at.
However, you can get great results by simply stripping the anodizing in a bath of Jestco Products anodizing remover, clearing the residue with 0000 brass wool and then taking the body to a buffing wheel.
Yes, the below NRs have been drilliumed, but you get the idea:

As far as polishing: anything can be polished, but not everything should be.

I'm just a novice at this Campagnolo thing but I like the satin finish.

Drillium, your derailleurs are gorgeous! Do you apply a wax or anything after polishing them?

For the record (no pun intended) the rear derailleurs are anodized, the front clamps and pivot arms are not anodized. Here's another "smooth" one to check out.

I reckon Chombi meant "gussied up".
Does gussying them up make them shift any better?

I held the opinion that the rear derailleur got more attention prior to 1971, the transition of the surface at the top pivot was hand dressed often to an organic surface flow, the later ones were not dressed.
On the front mechanism, Campagnolo did it appears make some process change, material or casting method or post casting finish that leaves the body and clamp on the earlier units (before the extension to beef up the top pivot root)
dull and sometimes rougher.
It was the lack of a cir-clip on these intermediate pieces with no screw retention that caused more than a few to bend the upper pivot, I had to replace the body on my 1971-72 production front to fix this. It caused slow downshifts as the pivots were no longer parallel.

Thanks guys, for posting the pics!
The pictures remind me of how a component can be made so beautiful and intricate to compliment a bike aesthetically, but after seeing the pics, I think such elaborate looking mods will work best only on certain bikes. Such elaborate "filligree" work might look lost on bike that have plain graphics and lugwork.....Which is the case with my project bike that has plain (but chromed) lugwork without any cutouts, but the paintjob on it is a very deep looking clear Imron finsh over CF (which I think what clashes with the crudish nature of the finish on the original NR derailleurs that came with it). The frame looks really slick, but does not have enough elaborate detail like cutouts and pantographing to match up to drillium and cutout mods that one might do on the derailleurs or crank...except for maybe polishing to mirror finish.I think I will just short cut the process by just mounting my better finished Pat. 83 NR RD on the bike and look for a similarly newer FD to match it. This, with a Campy SR crank will complete the cleaned up picture for the bike, drivetrain-wise. The 1972 bike would still look correct generally with the newer NR/SR drivetrain. It won't take any elbow grease on my part but I guess it will be hard on my wallet. I'll just keep the 72-pat RD, FD and the odd custom drilled 1st gen DA crank that came with the bike stashed away, so they can be reinstalled back on the frame as original, if I so desire one day.

Just wondering DD, what are your basic tools you use to do your fantastic drillium work. Other than exceptional artistic talent, I'm just wondering if it takes something more specialized than a nice drill press and maybe a Dremel set?
That De Rosa(?) FD looks just perfect!

I just use a Dremel - along with a boatload of pre-prior-planning and patience
One day I will get my lazy arse in gear and finish up the third installment of my tutorial thread. For one, I need some nice weather and for another, I need to feel I have crappy legs on a beautiful day for riding.
Watch this space; I have a small pay-it-forward drillium project that I may just be doing this weekend. I'll take in-work pics to give an idea on how I do some of this stuff.

Drillium Dude, You mentioned a "tutorial thread" in post #19....is that for real? If so, can you give a link for it, or tell me how to find it? I love the DIY info even if I can't do it myself. Thanks!

I did these two tutorials about a year ago - unfortunately, most of the pics are gone because they were hosted to my Flickr account before I went Pro (and there wasn't room for everything before going Pro).
But the writeups may still be able to tell the story
Part One: https://www.bikeforums.net/showthread...%29?highlight=
Part Two: https://www.bikeforums.net/showthread...%29?highlight=
The biggest issue I've had with the drilling part (Part Three) is the need for a second-party to take the photos while I drill. I only have two hands, you know
I suppose I could go back through my archives and see if I still have pics to update the two original threads again - or take new ones. But I'm really stuck with the drilling issue unless I take photos with the part/Dremel in situ and not actually doing the drilling at the time.
Would that work, do you think?

DD, THANK YOU for the links to your first 2 writeups. They're fantastic! I would love to have seen the actual photos, but you give such clear and detailed information in your writeups that it's easy to visualize most of what you're doing. I would never ask you to go to the time and effort to repost your original photos just for my interest. I'm grateful you're willing to share your talents with all of us here on C&V.
I wish I lived near you, I love taking "action" shots. I think your idea of taking photos of yourself with everything in "situ", as if you were actually doing the drilling, would work fine. I don't think there would be significantly more to see in a still shot even if you actually were drilling. And your so very professional descriptive writing of what you're doing could cover whatever little that might be missed.
You might need a tripod or table, etc. to hold the camera and use a shutter release "timer" on the camera, but I think it would work out fine.
Thanks again!!
