I'm pretty sure the planks are only obtainable from Logan at the moment - or if you /can/ use the axe somewhere I haven't found where.
Did you see the two of them interact on the track? If not, check Bareshade and do more quests there - you do have to, for example, convince or discourage Logan from interacting with the camp. What have you done in Bareshade? And did you see the Tank/Scar discussion on the Track? Have you met Jester?
