Trying to add a crown to a cylinder so that it is 25mm dia on ends and crowned to 30mm dia in middle. I am sure there is a simple way to do this?

Look up the tutorial on using the loft command.

Sketch a 25mm circle

Copy it along a line as many repeats and spacing as required for your desired length.  
Increase diameter of the centre circle(s) to 30mm  
Use the loft tool to join them.  
Use shell tool if you want to make a hollow form.
