I made a cutting board for my wife. I used maple and after I added
canola oil for 24 hrs, the wood had splinters in the corner. Big inch
I resanded and oiled it. This time with much higher grain sandpaper.
I was wondering what would make the wood split like that?
I have heard it said that you shouldn't use vegetable oils because they go
rancid, I have also heard from a lot of people that have been doing it for
years with no problem. I have never heard of a case where it actually did go
rancid. Sounds like one of those things that someone suggested as a
possibility and people keep repeating it.
I would think that most cutting boards are washed after every use. So it's
not like it was sitting for long periods of time before the old surface was
washed off and a new fresh coat was rubbed on . Maybe the first coat was
/has cured and the top coat acts like a barrier to keep the first coat from
going rancid. Just a thought.
