having recently bought a frame sans forks I have now acquired a suitable pair that will be just the job if I can extend the thread on the steerer tube by about an inch further and then cut the surplus tubing off.....can this be done with a suitable die at home or is it a job for the professionals, also it's a standard 1" head tube with British threads so am I right in thinking 1" - 24tpi?
cheers

Its easy to do. But the only people who will have the tool is a proper old school bike shop. If your friendly with them, go in and ask to use it. Just screw it on following the existing threads and slowiy, gently work into the new area with several passes. Ive done it before, was no problem at all.

Trying to cut a fresh thread where there is nothing to start from however, now that is horrible.

^ why so horrid to start off a thread? Unless you are using a bottoming-out die, in which case there is no taper to lead in.

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.
