I was trying to kerf 1/4" ply for a few hours on Sunday but it wasn't working out. I think the problem may have been cheap wood, any minor warp was changing the depth of cut significantly enough that it would want to crack at that location, even after soaking.
I picked up a sheet of better looking 1/4" Luan yesterday, will give it another shot

You probably already know this but make sure your kerf "grooves" run WITH the grain of the exposed side. Plywood axle strength is against the grain, like laying subfloor in a house is perpendicular to the floor joists. It will bend with the grain if laid parallel. In your case, you want the bend.

Maybe I am over simplifying but can't you just use a radius-ed corner finisher similar to used in kitchen cabinetry?
Its just a very large quadrant milled section, you can see it on the island counter in the picture below.

It makes it more bendable as opposed to trying to bend it perpendicular to the grain. If you took a 3' square piece of ply and set the ends on concrete blocks, then step on it in the middle, you would notice the difference depending on which way the grain is running.

I'm not sure Martin, we need Tony to chime in....I am a retired "carpenter" who built structures not cabinets, while Tony is a true cabinet maker. We both worked with wood but big difference in skills and knowledge. I could build you a house while Tony could furnish it

That's exactly what I'm trying to do, and the simpler the better!
Not sure why that never crossed my mind
Can i buy it at orange/blue/green hardware stores?
Tried searching and didn't find, maybe I don't know the right keywords?

It's not exactly helpful, but in the UK I can walk into any kitchen cabinetry/joinery outlet, not the generic big box stores, and pick up that part.
They come already matched to the kitchen cabinetry finish/quality

Sedona? Not for me, more like southern Colorado or Northern New Mexico

With two car ports to keep the rain off?
Or isn't there any rain in southern Colorado/New Mexico
Sorry Rob, please have your thread back!

Sedona looks nice, as does southern Colorado
Weather depends greatly on elevation and microclimate, i would definitely go for somewhere alpine, skiing in the winter, hiking in the summer
Not a lot of rain I hear, but hail is a risk depending on the location, definitely want to keep that off the airstreams

They are MDF but it looks like one of these might work if I get the proper radius measurements (which I will also need if I go to a cabinet shop)

So I did what I normally do when I have no idea what I'm doing... Wander around the hardware store aimlessly until something jumps out at me
Being a jack of a couple trades and a master of none (at least none relevant here). I grabbed a piece of double wall vent pipe that looked about the right size.
The outer wall was thicker gauge steel, which would probably work better, but i don't have the tools on hand to properly work
The inner wall, however, was both about the right size, and aluminum
I think it'll work!
