Bado Posted December 1, 2019 Report Share Posted December 1, 2019 Hello All, I started to make cutting boards from black walnut. I flatten boards using the planer. Then when when i apply the mineral oil, the boards will warp overnight. It drives me crazy. I read lot of info regarding warped cutting boards but majority of time it is related to water contact. This is not my case. They warp after mineral oil application. Am I doing something wrong or boards will never be perfectly flat and I am just too picky? Any help is appreciated.

Tpt life Posted December 1, 2019 Report Share Posted December 1, 2019 Are you flooding, or applying to only one side? Are you leaving wide boards or talking about glued smaller stock? Many will pond the oil in a tub and immerse the whole board. Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted December 1, 2019 Report Share Posted December 1, 2019 Standing the board on edge to 'dry out' helps keep things even with water or oil. Typically, oil does not 're-hydrate' the cells of the wood to produce swelling and warping, though. Quote Link to comment Share on other sites More sharing options...
Bado Posted December 1, 2019 Author Report Share Posted December 1, 2019 I don`t flood the boards, however i apply oil on both sides the same time. I try do do it as evenly as possible. Also, I dry them sitting on their edges. I don glue small pieces together. It is always one piece of wood per a board. I even tried different brands for oil. I am really puzzled. The wood that I am using is kilned dried and I keep it it my workshop for a good week until I make boards from it. Quote Link to comment Share on other sites More sharing options...

lewisc Posted December 1, 2019 Report Share Posted December 1, 2019 I have had a board cup before but that was when I left it flat on a bench. Once I stickered it, it returned to normal. From then on I always screw small rubber feet to the underside. How thick are your boards? Quote Link to comment Share on other sites More sharing options...
curlyoak Posted December 1, 2019 Report Share Posted December 1, 2019 Has the walnut been completely dried? Is it the center of the log? Quote Link to comment Share on other sites More sharing options...
