Scott...I've been working on my edge trim the last few days. I'm shooting for a 1.5" radius rounded solid ash edge, so it may be a lot more than you want. Looking at the curves on your profile, you can easily trim that out with wood should you just want to rip some strips and glue them on....here's what I'm doing...
First off...to round over such a thick piece, I first had to lay out where I wanted it to go on my profile...and give myself something to clamp to.
I planed to steam bend 5 strips of wood and glue them together. There are lots of ways to bend wood and set up a clamping form. I used a big dowel that I cut into pieces and knocked off one edge with a chisel to give something for my clamps to rest on.
I steam bent the wood on a teapot setting on a Coleman stove. I use a reclaimed piece of discarded gutter for the pipe stuffed with a rag in the end. About 15 minutes per 1/4 inch of wood thickness...
Clamp it up, let if dry for a day or two, then glue and reclamp. Your in business for a solid edge.
This is overkill for most. Depending on the type of wood you want to use, you can probably bend a 1/4 inch strip of wood around your radius without any steam bending...Hope that makes sense...
