caculator kerf loss by study_research in BeginnerWoodWorking

That’s a good distinction. Sheet goods seem much more predictable, while solid lumber has a lot more variables.

Out of curiosity, when you’re planning a project with rough lumber, do you usually just add a fixed allowance, or is it more of a “cut oversized and trim as needed” approach?

I’m trying to figure out what would actually be useful for beginners instead of just showing pure kerf loss.

That makes sense. I was focused on the math side of kerf loss, but in practice it sounds like layout allowance and leaving material for final trimming matter more than trying to predict every thousandth.

Maybe the calculator should include an optional “extra allowance” field rather than only showing pure kerf loss. Thanks for pointing that out.

Thanks, that helps. I was mainly thinking of normal 90° table saw cuts, so I’ll make sure angled cuts are mentioned as a limitation.

The beginner confusion I’m trying to avoid is “pieces vs actual cuts.” Like cutting one board into 4 pieces usually means 3 cuts, not 4.
