building a treehouse part 2

  • Posted on June 9, 2012 at 2:14 pm

i finished up the base by cutting a piece of foamcore to fit in the hole of the frame,then glued it down. you can see it fills the space pretty exactly. this is so neither the flooring or the base will bow when i attach the tree stump

then i added back the hardboard backing and glued this to the foamcore, using a stack of books as weights to hold it all flat as the glue dried.
i trimmed the boards so that they were close to the frame, then cut 1/2″ square strips of wood 11-1/2 inches long for the side supports. i first attached them to the corners of the second frame then the corners of the floor. i tried screwing them in but didn’t have the right size square head attachment for my drill so ended up drilling holes slightly too small and then hammering the screw in. odd but it worked.

here kiri and noah demonstrate the size. i probably could have made it a smidge shorter, but the proportions are nice this way so i’m happy with it.
