thats a lot of sanding Ted...you can go slow with the planer as well....measure the depth of concave you want...as primitive as it sounds...a rusty nail works good...just push it into the foam next to the stringer to the depth of concave you want, and plane down to it...you will see the mark it leaves in the foam, plane down most of it and sureform and sand the rest....good luck
Thanks arkgee for the top tip - I will give that a crack.....I hate having to sand more than I need to but had been happy to take baby steps this early on

I will take some cement pills and harden the farrrk up.
