How about a duplicator like the ones from PSI?

Not that time consuming, Block both ends equally and run a pencil standing at 90 degrees to the profile. I done multiple ballusters for doll houses several times, when they are only 1.5 inches long, a mistake stands out like a flashlight at night. But I used that as a guide to cut plexiglas for a homemade duplicator.

For a treehouse, I turned ballusters for the stair case using the same system, these were 2x2s that 2.5 feet long. The customer brought a picture, together we turned one, then I made a pattern. Then for a couple of days I turned the rest of them. As long as the guide point moves in the same plane as the cutter and the guide stays on the profile, they will match up.

I considered these jobs as easy money, because I also charged for making the pattern and the duplicator. Half the dollars up front, the balance on completion.

That one is a knock of the Ankar duplicator, it was designed for miniature makers, as in small scale dollhouses. It works, but for just a onetime deal, it is easy and cheaper to make one following some plan on Google. If you want to have fun with miniatures, search "Tom Walden miniatures", warning that can be a bottomless pit. both money and time.

I have used a storyboard to mark my high and low points. Calipers for measuring them.
Hold the caliper behind the blank where a low point will be then turn it till the caliper or open end wrench slips over the blank, then turn your high point to match that. Do same for the lows and connect the two. The needle like profile transfer things can be somewhat helpful when you get it close. If you are the one turning the first one remember you have to make others to match it and don't make it harder on yourself than you need to. I made this sound much harder than it is to do, it is a lot easier than it seems like.

My sister-in-law once showed me her set of beautiful set of hand blown wine goblets. She told me she hated them because if you looked closely, each one was slightly different. Indeed they were. Dinner was later served with very ordinary wine glasses that could have come from anywhere, but at least every one was completely identical.
