Not quite. Gary Watkins (Sierra Valley) made very nice ones. Jason at The Train Dept now has the business and sells them. They look like this.I'm guessing Gary Raymond wheels, only guy who made anything approaching fine scale.
I have never had a problem removing wheels from axles (getting them back straight is the bigger issue!) With the wheel off, you can put a shaft/bolt through the hole with a washer or two to hold the face of the wheel. Then chuck the bolt from the back of the wheel and you shouldn't damage anything. I use a power drill and a file for this kind of thing, but a lathe would work.They are a press fit and not a lot of resistance to spinning on the axle or insulator.
