Centering the pith!
« on: February 06, 2016, 11:28:42 PM »
Was just over on Woodweb and came across this comment from Doc on KD wood:

"Twist results mainly because the sawmill cut the lumber at an angle to the grain.
Perhaps it was a crooked log. Perhaps the sawmill cut parallel to the pith and not parallel to the bark. -

Unless there is sever taper to a log I mostly cut parallel to the pith.  My ideal is to be able to cut the pith out with the 3/16" kerf of my Lucas (I dream a lot too.  ;D) With the exception of large hardwoods where I cut parallel to the bark when trying to get highest grade, like quarter sawn white oak and then make a corrective cut at the center.

Construction conifer lumber (western grading rules) allows up to a 12:1 slope of grain which I think is really excessive.

So what does everybody else do?

I mostly cut parallel to the pith as well.  Have not done a lot of quarter sawing nor a lot of sawing for grade with hardwoods.

Parallel to the bark for grade sawing.  I do as Red Oaks Lumber outlined.

The bulk of my milling is eastern white pine, I pay little attention to the pith. If I'am cutting timbers for framers I'll make feeble attempts to center it. Frank C.
