Thanks Maka
The only hand planes I normally use are 2 Stanley Small Trimming Planes. Mine are modified though. The blades are super high quality steel. And they are ground in an arc. See photos below. One is ground with a larger arc and the blade is set shallower for finest cuts. The other is ground with a tighter arc and is set to a deeper cut. I rarely use this one. I keep them both sharp via diamond sharpening stones.
I make sure that my final power planer cuts are as clean and shallow as possible, including those over the stringer. Therefore the amount of sanding I have to do is as little as possible. And that causes the stringer to rise as little as possible, requiring the least hand planing to level it with the foam. So… in answer to your question…
The steps outlined below will show at what point I hand plane the stringer. The power planer steps are done with A Skil 100 planer.
