Just to understand what you are saying, you plan to use an ahead stem on a threaded fork?
Your goal is to build a cheap bike. Making bad decisions from the start usually makes the project more expensive in the long run.
Have you put a wanted post for 1 inch fork and seen what people have to offer?
Tifosi is a cheap option for 1 inch carbon fork. I can't give a review of them but they should be easy to find for you if cheap carbon is what you want.
I've seen it done (clamping on the threaded part) but I understand it's not recommended. Thanks for the recommendations anyway, I'll be looking for a fork on the internet and on my local second-hand site (I'm from Belgium).
