Milling out the butting on a head tube

Hello!

I've just got my hands on a LeMond Alpe D'Huez, 853 steel 57cm etc. There is currently a appears to be a 1" headset, but the butted walls where the cups fit are really quite thick whilst the main tube is considerably larger. I was wondering if it was at all possible to take out 3mm of the butting in order to accommodate a larger 1 1/8" headset. This may be a really stupid question, but my older Raleigh frame has a straight gauge head tube and I've never had any issues with flex etc. As to why I'd want to do this, simply I have a bunch of 1 1/8 carbon forks which I'd like to utilize, otherwise I'm looking at some Columbus minimal's which are 150+

Cheers,
Joe

No, don't do it.

If you have to butcher it, I think a better option would be to swap the headtube out completely. Really though, just sell a fork to buy a 1" fork.

Inverse shim?

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
