I have a Grizzly G0586 8" with a decent length table. I got some quarter sawn white oak from Frank Miller lumber near Richmond, IN last fall and it has been in my basement shop since then. I have a dehumidifier in the basement. Frank Miller does a lot of QS and is known for it and very reasonable prices.
My problem. I took down a 4-1/2 to 5" wide @8 ft board today and cut off about 8" on one end that had a knot and discoloration. I cut two 39" pieces out of what was left to mill for a drawer front. I like to work so I can cut out the sap wood where possible. Both these board went through the jointer in a very weird way.
I mill through cupping side to side and end to end etc... but these pieces hit the blades on the first 6" or so then no contact, then 6" or so in the middle of the board then no contact, and then hit the blades on the last six inches on the first pass. I was able to mill them flat, but I've never seen a board that had undulating cupping in it and not two piece cut from the same 8ft piece.
Any idea why it did this?
Thanks.
Brian
