Another Knee question.

[ccx2]

After you have cut out a Transom Knee to the shape you want it ,how do you go about rounding off the upper and lower curved edges that will face inside the boat? Round over Router bit? Sanding block and a patient eye? How do most do something like that. All the rounded over edges ive done on my build so far ive used a sanding block but the knees have some tighter curves that would make it not easy.

A round soled spoke shave,

As you've already had success with sandpaper perhaps roll your sandpaper around an apropriate sized piece of dowel.

Maybe not the best first project if you've never used a drawknife before.

If you're new to this, you'll have better results using rasps than blades.

After the rasps follow with a worn machinst file to remove the teeth marks before sanding. It'll save you a whole bunch of expensive sandpaper over the decades.

Many consider rasps to be crude, but in reality are quite precise as each tooth cuts only to a uniform depth.

Or if you are a hick like me -

Ran across David Mede's excellent photos of building his Atkin skiff, with this nice one of a transom knee, part solid and part lam -

Thanks Guys for all the info.

There is a small hand held, before electricity, tool that does the job.Can't tell you the name, but it's a cross between a church key and a potato peeler, serious.

For an open dinghy? I use a r/o bit; 12mm for the underside of the knees etc. before fitting, then 6mm around the entire perimeter of the boat, inside & out, after everything is finished.

Candyfloss has a really nice little dingy floating around on one of these threads so he might have it right. Personally, I like to use a rasp. It's easy to control so you probably won't get carried away, which (in my experience) is easy to do with power tools, especialy belt sanders.
