Profiled Cores

A freind is giving me a surface planer and he said it pobably needs new knives. There's a couple of nicks that will cause raised lines on the finished piece. Then I started thinking, what if you made two large raised portions on the top of the core? How would that effect flex? This could be done with a molding planer or by filing the profile into some beat knives.


Forgive my crappy paint rendition;

It would add stiffness lengthwise, but probably not affect torsional rigidity much. It would also add some weight unless you made the rest thinner - but then you would have more twisting issues.

You could do that, make it thin and add glass or CF to control your flexing properties
