I've done it. You don't need the park tool. All you need is a cheap 1" x 24tpi die. I got mine on evilbay, I think it was $13 for the die and another $15 for a die stock (die handle). There was no guide, but I felt it wasn't necessary, as long as you're starting from established pre-existing threads.

Here's one!

Many forks' threads are a little oversized compared to 1-28 UNS. Your die may take off some material from the existing threads. It's OK. If your die is the split kind (nicer) and has an adjustable screw, you can expand it a bit to stop this happening so much. Mine did not, and it was fine. Maybe I will cut a slit in it with my grinder for next time.

Yes, the park tool's better. But you're not doing this every day. So don't worry, be happy! It was worth the $35ish in tools, not to have to bug a bike shop about this. They are more interested in selling rich people ebikes anyway, and that's fine.
