How can I cut a 3" long/0.25" deep slot in the back of this wooden counter? the slot is for a monitor mount.it's mounted to a wall via support arms and 15' long so i can't really remove it. note that obviously the slot is in between the support arms!i feel like this should be simple but i'm baffled - happy to buy tools, naturally.http://ift.tt/2tN3QQG via /r/DIY http://ift.tt/2u7BcJC
