I just finished routing my first ever raised panels with an Ogee profile.

Now I’m wondering how to sand the end grain on the Ogee section.

I’m afraid that if I hand sand across the grain, it will still scratch, even though it’s end grain.

Any recommendations?

(Note: the long edges are actually straight, but the camera angle makes them appear curved.)

Different grit sponge sanding blocks.

Why do you want to sand it.The key is to make that profile cut without the need for sanding.
Only after your seal coat then only a light sand with the sponge to knock down the raised grain.
Looks like Bulbinga yikes.

It’s endgrain, so I just sand it crossgrain. By the time I get to 400 or so, scratches aren’t noticeable. Check for scratches by wiping it with Mineral Spririts.

My wife is the master finisher on our interior doors. All she does to the panels is to make sure it’s smooth on the end grain. She works it vertically (along the grain) with the end of a Preppin Weapon block.

I’ve used pieces of swimming pool noodles for sanding different contours

Take your time and go with the grain. I would use a sanding block that is wood, then rubber sole, then sandpaper stuck to that.

I make a sanding block by laminating a piece of 6mm craft foam to the bottom. The block is sized to accommodate a 1/4 sheet of sandpaper. It will conform to many different types of curved profiles.

When sanding end grain, I always sand too a higher level grit, say 320. My usual sanding is 100, 120, 150, and 180. With end grain I continue with 220 and 320. It really closes the end grain so it will not soak in as much stain or finish…

Ugh! Sanding end grain, especially if it is contoured, is a chore I try to avoid.

Unsanded endgrain is visible if a transparent finish is used, you can’t hide it, then again will anyone but you notice it or really care?

The foam backer techniques mentioned are excellent, but if I have a lot of linear feet of grain to sand, I’ll make a dedicated sanding block.

On a test piece, I’ll coat the profile with a heavy coat of paste wax, then form a block with automotive body “Bondo”, basically making a negative casting of the profile.
This then can be used as a sanding block with a suitable thin/flexy layer of sandpaper that easily conforms to the profile (or you can spray glue a piece to the block and clamp it to the profile while it dries.

Thanks for all the replies…

I made a home depot run for foam sanding blocks … those suckers aint cheap.
I also ordered a Preppin Weapon off Amazon… very nice sanding block, but pretty darn pricey at $20
I also used the 5/8” rad contour sander on my multi-tool.

This was a lot of work and a PITA, but the results were pretty good… Here’s one of the panels with a quick spray of Seal Coat on it…
