Crank up the roof with this cool jack
take out the old post (that was fun)
Install the new plate for the new post to go into
Uncrank the jack and
Voila! New post!. Needs a paint job and the railings, but it was going to rain, so I had to move quicker than I wanted to. Railings should be easy, paint and then I'm done! Woo Hoo.
