Pyphagorus in milling?

[Tippin Alaybye]

Anyone use this milling stems to square? Saves time and waste

Shouldn't there be a degree angle in there somewhere?

Sort of, but my logs are never perfect cylinders or slightly tapered cones. That means I have a general idea but am then trying to account for any slight bend. I can sometimes get slightly more out by biasing off centre a bit at the larger diameter end. I end up trying to get the best centre line, then work out where that will hit at each end, then work out the shortest distance to the edge from there and use that as my radius to calculate the square as above. This is a lot easier to do than it sounds!

Nah. A squared = B squared + C squared. Angles are for SOH CAH TOA

Got it...had a brain freeze. 

Just done the calc and it's spot on. Cheers

I get you
I used to use one of these but took too much time

takes me back but to be consistent H(ypotenuse) squared = A(djacent) squared plus O(pposite) squared

ive actually got interested in my old o level subjeks, well maths chem physics and biology. i found i take it in and understand it when reading the course books for fun rather cos sum teacher tells you too. i dont need to do the inglish ones thou
