I have a ?, after oiling sanded end grain cutting boards

[Terry Starch]

Hello, I’ve made lots of end grain cutting boards. Ive had no problem with a bunch of them but every so often after I oil it completely, I can feel the seems where I glued the pieces together. What causes this? Thanks guys...

That’s been my experience too. I say it’s glue creep I thin down glue when I think it’s going to happen.
Hardmaple makes the best end grain board. It also can be tricky to keep glue lines small. Lots of clamps
Good Luck
