Ive got an infamous Dolan Crack champion frame that cracked at the seatpost collar. After exploring multiple possibilities (custom quill seatpost, milling it down into a new seatpost collar...etc) ive come to the conclusion that the cheapest/most efficient way to fix this would be to grind/file down the top of it, and glue in a long insert for 25.4 seatposts with a clamp collar on the top of it.
Quill seatpost would be nice as I very likely wont be reselling this frame so adjustability is not that important, but its only got like 10cm of round diameter in the seattube, after that it expands into the aero shape, and the quill would just further reduce the contact (?).
Hence glued in insert with new standard round clamp. My problem is that in London I dont have access to any workshops. If I take it with me to Hungary (where ive got access to workshops), the price of luggage will be more than buying a used frame. The moment I pay someone labour to do it for me, same problem occurs. I have contacts to make the custom insert for me.
Is there anyone with a workshop who wouldn't mind having me around for an afternoon in exchange for a few bottles of their favourite craft beer, and the fact that this frame wont be binned but gets a new life?

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.
