Patience, grasshopper. Do you have it set up so that it's soaking? The ammonia will only penetrate a tiny bit each day. Rap the stem with a hammer to vibrate it. That will help.

I had a seat post that took 10 days in 10% ammonia. You are using industrial ammonia, not household, right?

No, household

The fork doesnt have a hole, so I couldnt flip it upside down and soak it that way, I took out the bolt and filled it to the top.

I used the ammonia trick on a aluminum seatpost, in a steel bike, and it worked like a charm. I used household ammonia, and did not dilute it. Pored it in the bottom bracket hole with the bike upside down, and waited about an hour, and that is all it took.

Don't leave it too long, as I have herd that the ammonia eats aluminum.

Finally got it out, soaked it in Ammonia for a few days, then froze the stem with some CO2 to try and shrink it, then beat the bottom of it with a hammer for about 30 minutes, then it finally popped out.
