Before routing make marks on the shaft where the shaft meets the point of the end panels.
If you want to stop the routes at the top or bottom of the column be sure to set stop blocks at the beginning and end of the router path.
After routing loosen the clamp and rotate the shaft until the the first marks you made align with the the next points on the end plates. Then tighten the clamp, make new marks on the shaft and route. Continue this until complete.
