Holy Heck
This was one of those times when I planned on reading the first two paragraphs to see if I wanted to try a story later, then ended up just reading the whole thing, so your hook is obviously working.
You mentioned elsewhere that you enjoy Stephen King, and I can absolutely tell that was the soil you grew your writing style out of. I caught feelings similar to my experience with Jack Torrance, and other characters where King has tried to get inside the head of an abuser and understand the monster for the ugly, awful, but ultimately pitiable thing it is.
We can never sympathize with the father, but we can empathize with him - especially those of us who have also endured abuse. The tyrannical parent "always seems to know what to say" because they aggressively discourage their victim from ever making their own decisions, and it turns off something in a child's brain that might never come back on. They're like paralyzed deer for the rest of their lives, terrified to make any decision at all, because what if its the wrong one?
Daddy is dead and can no longer hurt you, but the body keeps the score. The body remembers that punishment could come at any time, for any reason, or for no reason at all. Eventually part of you wants to punish /yourself/ just to get it over with, because the only time you didn't have to /worry/ about being hurt was in the cool-down phase right after you already had been. The pain becomes associated with the relief from pain.
It's this sick, twisted knot of psychological garbage that somebody who never got help could never be expected to untangle themselves from, and it just keeps getting passed down, hand to hand, until somebody is strong enough to break the cycle. That's everything I see symbolized in the whipping board: you managed to get all those feelings in there in a way that resonated with me, and it was a damned good time. Well done.
