Homebuilt Stevenson Screen / Sheild

Hi peeps I am towing with the idea about building a Stevenson Screen ( shield ), not 100% sure yet as my DIY skills are not the best, more so when it comes to wood :oops: Are the proper screens fan assisted? Are the louvers specific dimensions? Do they have to be a specific size? Has anyone had any experience in building these? how hard was it? did you have anything to work to?
