So I am retired and exploring different stuff. I recently glued up a curved panel. Finishing the outside is easy. How about the inside. I prefer to use hand planes. That seems out of the question.

Thank you so much for the link.
I have tried the scraper. If you saw the inside of this door, you would realize I don’t have a year to smooth. Ideally I would like some kind of plane solution. I even considered making a plane but I have no idea how I would construct a chip breaker.
I guess I could uses some type of sander/grinder and then move to a scraper. I was thinking some type of plane curved across its base.
How did Krenov do it so often.
A scorp or a compass plane.

In shave seems like the best bet. I have a compass plane. Can’t seem to operate it properly.
I don't know, but isn't that what a curved bottom spokeshave is for?
I was watching an ENcurtis video this morning, and he was doing basically the same thing.
I have never seen a curved bottom spokeshave

You want the convex bottom 'un.

I built a bed with a coopered headboard. https://www.tailspintools.com/how-to-join-long-boards-with-dovetails-bed-frame-followup/ (sorry for the link, could not locate the JPG... scroll down a bit for the headboard)
I bought a #35 burner plane, ground the iron to about an 8" radius, and hogged open the mouth. Effectively a wooden scrub plane. Starting with snapped lines I went deepest down the middle of each stave, then a bit less deep beside that cut until it was curved but corrugated. I got off what I could with the 35 by moving the iron in and out while resting against the scallops.
I followed up with the scorp at 45° to the length and smaller scoops / travishers, finally finishing with scrapers and sanding. I did not go for a perfect curve in the back because it's always gonna be against the wall, but it would have gotten me there.
Fabulous. I knew guys with great suggestions were out there! I really would like to try building a plane similar to what you have shown. I have a standard plane I made years ago.
You could make a gutter style plane with a large radius. However, you would need to be able to adjust or make a chipbreaker to that radius or you'd be asking for trouble. If the planing is light, you can make a single iron plane to do the same bedded at about 60 degrees.
Presumably if this was done by hand, the planing would be close a radius tighter than the inside curve and then cleaned up with a scraper.
Look where your gutter plane took me: http://www.crownplane.com/catalog.html
You are a genius!!! I have wanted a plane like this forever but the chip breaker always discourage me. These look like the ticket!
A world of knowledge at my finger tips. I just have to ask
If you wanted to use power to get most of the work done, you could get almost done with a router and carriage for it. Build a box to hold the router, and a carriage (guided by strips along the edge that ride on the outsides of the coopered panel.) Arrange the box and carriage construction so that the box pivots from a point equal to the radius of the panel's inside curve. Regrind a fairly large diameter straight bit to a bit tighter radius than the above radius, and ease the corners slightly. Set the bit so that it just skims the joints between the boards (or at the worst joint, if they are not perfectly aligned.) When you are ready to go, tighten the pivot bolts before routing. You don't want that thing wandering around uncontrolled in the inside of the panel!! If everything is accurate, you will have a modest amount of scraping to do to finish up. For that, we always sharpened a curved scraper (again, with a bit tighter radius); we sharpened it at a 45º angle like a cabinet scraper rather than at a 90º angle like a card scraper. With the 45º sharpening, it can take a significantly heavier cut. I did a similar thing to create a giant crown mold (5.5"x12"x22' with 3 curves in it.) I'll post a picture later if I can find it.
