strike, hit, beat, hammer
椓 centers on forceful impact: striking, hitting, beating, or hammering something.
椓 combines 木 (wood) with 豖, which likely contributes the sound and relates to striking or beating with a wooden implement.
The left side is a tree 木, and the right side 豖 looks like a pig 豕 with an extra stroke, suggesting a heavy wooden mallet used to strike or beat something.
For タク, imagine a wooden tack hammer striking a tack: tack -> タク, and the wooden mallet drives it in.
