3. Refine the End Grain Profile with a Hollow Plane
Now that you’ve removed the majority of the waste wood with a jack plane, you can move onto using the hollow molding plane to clean up the quarter round profile. I usually like to use some wax or tallow on the bottom of the hollow plane to make the end grain planing easier. It reduces friction. Another trick for hand planing end grain is to wipe denatured alcohol on the end grain. That’s probably not necessary for this operation, but it can help.
Slowly work the hollow plane along the rough profile, holding it at different angles to make sure you get the whole profile shaped. And just like with using the jack plane, don’t go over the edge, but come from both sides so you don’t blow out the end grain:
And once you get close to the pencil marks with the hollow plane, then stop. Below you can see how nicely the molding plane rounds the profile. Of course, the bottom of the profile still has a bit of a flat, but that will disappear when you come back with some fine grit sandpaper to smooth the entire quarter round molding profile.
And remember, as I mentioned above, if you don’t have a hollow wood plane, you can use a block plane to create the profile:
Once you’ve finished the first end, repeat all the same steps on the other end of the board: use the jack plane to remove the rough waste wood and then use the hollow plane or block plane to refine the profile. Once both ends are finished, your board will look like this:
