Pyphagorus in milling?

Recommended Posts

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

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