Title: Problem knot
Post by: stuckinthemud on May 31, 2020, 06:31:14 am

Just roughing out a scotch broom billet and found this. The photo is edge-on, the knot is about 1/4 " deep, I reckon it's going to come to the surface just as I reach floor tiller and is 6 inches up from the fade(https://stuckinthemudsite.files.wordpress.com/2020/05/20200531_1243525207563965815549335.jpg)

Knots like that are a pain in the neck. Good luck

Looks like you have enough meat to work around that knot. You may have to keep that area a bit stiff and clean up the back ring. It back ring should go down into the knot without a violation.

Game over.....
Can't tell for certain from the picture but it looks like that knot will cross the belly making a large weak spot. The problem with leaving spots like this a bit stiff is that strains wood either side more even if the initial problem holds up eventually bows with stiff spots get excessive set or potentially chrysal.

It doesn't cross the  belly, it is rising toward half way to the centre

What Pat said. You also have a high crown so leave the stave  a few inches longer. Jawge

You leave the area still like you do entering a fade. That doesn't seem to over stress the limb unless you make a hinge there.
