Heck, I'm not shy;

Here's a more recent pic;

My 70-ish Ganna has some chrome.

My burgundy P13

I built this in late 2009.

So, thanks to this thread I have made up my mind about painting my lugs on my project. I am keeping them chrome even though the chrome isn't perfect. Nice thread!

chrome vs stainless? what's difference

....you can't cook out of chrome?

I can't compete with a lot of the lugs that have already been shown, but here are my entries:

I call shenanigans...that's just about cheating isn't it?

My Privitera (Pinarello clone) - excuse the crappy photo...

The Nervex Professional lug on the left is chrome plated mild carbon steel stamped from sheet steel, while the Newvex lug on the right is investment cast polished stainless steel.

It's not easy to tell the difference, but the stainless steel lug won't ever pit or lose its luster when exposed to the elements while the chrome plated carbon steel will.

Love that Cinelli, Robbie!

Circa 1960 Capo, anyone? (Orange one belongs to a friend in San Jose, who bought his new in 1961. Capo #1 included only to show the shape of the unique Capo lugs of that era.)

Stan, I never knew the Nervex lugs were stamped. I always assumed they were cast and were some of the top quality lugs in their day. Thanks for the clarification.

I just had to comment- when the second page of posts loaded and I saw that this was at the top, I spat out my orange juice. Hysterical.

Nervex pros of course go back a long way. They were actually more or less designed to be a labor-saving alternative to hand cutting fancy lugs. They still require quite a bit of clean up and file work to look really, really nice - something Schwinn never did. There were cast lugs at the time - Hetchins used some on at least one of their fancy-lugged models, but most lugs were stamped ("pressed" being the more common term) and required considerable hand work. The Nervex Pros were considered to be of high quality at the time - and were put to good use on high-end models by a number of builders, Masi and Flying Scot providing some very nice examples. Cast lugs really started to come into greater use in the 70's - Albert Eisentraut had his own design made for his use. But they only really proliferated when Microfusione started really cranking them out in the 80's, and everybody had a set made up with their own name and logos cast in. The vast majority of the lugs of the post-war era into the 80's were pressed and had to be worked by hand - only in the 80's and beyond did cast lugs become the "industry standard."

Edit to note that in the immediate post-war era in the UK at least, cast lugs were common, and were superseded by stamped/pressed lugs in the mid-50's. They were of course very different from the precision castings that became available from Microfusione and others in the late 70's-80's.

The lug stamping process is beautifully explained in the 1994 Bridgestone catalog posted on Sheldon Brown's website. It looks like Grant Petersen's work.
