You can make the string of vertical fillets with the script found here
The script works because all the fillet surfaces on either side are tangent which is what the script is designed for. In the enclosed file I did one side of the model. You can do the other side by picking two of the surfaces that will be connected by a fillet just like the FilletSrf command. The script will make the rest of the fillets and do the trimming and joining.
The two red points are the easiest places to pick when the script asks you to pick the first and second surface with 1" radius.
