Hopefully someone can help me with this.
I cannot seem to get this right. This morning I was resawing 6/4 cherry to bookmatch into panels for doors. I was hoping for a 5/8 final thickness. All would have been fine if the blade had not curved inside the piece while resawing. I was left with a dished piece and a bulged piece. The dish would only occur in a portion of the piece. I would say only 1/4 to 1/3rd of the length of the resawn pieces had the cup and the remaining portion turned-out fine. Hopefully you understand what I’m saying—even though I’ve only known the English language I don’t use it very well.
Here are the steps I used to resaw:
-joint one face
-joint one edge 90 degrees to the freshly jointed face
-mark the opposite edge with a straight line approximately half the thickness of the board measured from the jointed face
-place jointed edge on table(table set 90 degrees to blade), align blade to line and push stock through blade adjusting for drift as necessary to maintain line on top of wood—In the past I’ve used a resaw fence adjusted for drift but found that drift would change from board to board leaving me with wedges instead of equally thick resawn boards
-Blade slightly forward on tires
Blade tension adjusted as follows:
-As blade was installed, back off guides and turn saw on
-tighten blade until flutter is removed
-add slightly more tension—this just about works out to where my saw says I should have the tension for a 1/2 in blade by the way
-cool blocks for guides a dollar’s width away from blades
-bearing a dollar’s width behind blade
-zero clearance insert
It is a Jet 12” bandsaw with riser and I’m using a 1/2” wood slicer blade which has not been used much so it should still be sharp enough.
Bandsaw tuning tips and/or help with my technique is greatly appreciated.
