Well, its set into place finally. Turned out to be super easy, as I was correct in thinking that it balanced close to equalibrium. Just a slight tug to pull the 2X4 supports out of the ground (only a shocking few inches), and it gently rocked forward onto a 4X4 on two blocks. Removed the plywood from the base. Just out of curiousity, and a little laziness, I reached down, grabbed hold of the point and lifted. It was so damn light and easy, so I just pushed it over into place. I still had one edge resting on the 4X4, the oposite edge had sunk about 2 inches into the sand/(Florida soil). Wrap the chain I used earlier around the 4X4 and yanked out with the truck.
Removing the rest of the form was a little more difficult, had to do a little digging to get it free. On the front was a 8x10 picture frame recess, the plywood was stuck pretty good, had to use a hammer and chisle (know its spelt wrong...).
Anyway, the pewter plaque I made slid right in with just a little encouragement from Mr. Hammer. Had thought to paint it white, but looks good natural, so going to leave it. Might look into some sealer after its had time to dry out some.
