Tips needed for vertical bends of pe railings

Hi folks,
I’m slowly working on a 1/400 scale kit of the SS Sirius. It’s a coal burning side wheeler. I’m painting a little as I go so it’s taking me some time. As I’m gathering materials for the build I came across an issue for me that I have no experience with. It involves pe railings. I’ve little experience with them. All I’ve ever done so far are horizontal runs and bends. For this build I have to run railings vertically over the curved top of the paddle wheels, i.e. railing curved and stanchions vertical. Does anyone have any experience or recommendations on how to do this?
Thanks in advance for your help.
