OK everybody get a good laugh out of the way right here at the start. I decided to make my first cutting board this holiday season, we had too much time off work. I started with some nice white oak that i have lying around. planed it and cut it into 1-1/2” slices, glued it together, and (ok here is the silly part) sent it thru the planer. Anyone who has tried to do this is now laughing and saying i remember trying this, everyone else is laughing at my stupidity! Talk about chatter, and this is the first time i have experienced kickback in the planer( glad i was standing to the side!) it broke the glue joint and sent a piece flying across the room! So i tried a few more times thinking i had something wrong with the planer, i’m a slow learner. So i thought i would throw this out there in case my conclusion is wrong, Never plane end grain! or i still have it wrong and am too slow to figure it out. Hopefully i have blogged my own stupidity before someone else does!
