uhhhhhhh how the heck do I make boards

according to the wiki you just place a log on a sawbuck and then should be able to start making boards
ok i got a sawbuck
i chopped a tree down so theres a log on the ground
now what? when i r-click it my only option is to chop it
when i l-click nothing happens
how the heck do i get this onto the sawbuck? :/
