"I know Ah Clem uses an arbor press. I put one on my Christmas wish list because it seems like it'd be something with many possible uses."
You do realize that you will have to start running and restoring antique toy trains if you get an arbor press, don't you?
I got mine years and years ago to press on pot metal wheels and have used it on many things (including full sized automobile parts).
I did recently purchase the MA tool for doing this, but have not tried it yet.
