I recently repaired a bunch of framing on my porch and replaced the floor.
On three of the posts, I cut off the bottoms just below the turning, then spliced on a fir 6X6 with pocket screws and gorilla glue. I rounded over the corners with a compass and they match perfectly. I did this because it always bothers me to see blatant "repairs" on posts, where the seam is obviously right there in the middle of the bottom square part.
Anyway, I just finished the floor, and went to take out all the crow's mouth bracing that had been holding up the roof.
Only the two corners came down to meet the deck. The middle three are suspended in the air about 3/8 -1/2".
All of the post bottoms are exactly the same length, and the distance from the bottom of the post to the bottom of the carrying beam is the same on all of them.
Now, somehow when I replaced the rim joist with 2X6, it wound up coming down lower than the old one which had rough cut X6, effectively lowering the edge of the deck 1/2" or so.
I just went up on the roof and jumped around over the carrying beam. Those posts are NOT meeting the deck.
Here's my dilemma:
I went to great lengths to offset my PT 6x6s on top of the piers in from the turned posts, so that my 1X trim will line up perfectly with the corner of the post all the way down to the ground.
If I have to cut 6X6 pads to jam in under the posts so they meet the deck, I'm left with two options:
1) do an extreme careful job with glue and wood filler and paint and caulk and try to have NO visible seam at all
2) if there is a seam, have to box in the bottom of the post with some sort of trim. this is a pain because it changes the look, the design I had planned with the offset, and also mess around with all my railing connections down low there.
3) I could run 3/4" thick lattice under my trim, thereby lining up with 3/4 trim if I have to trim the post bottoms. THis might look OK, actually.
The question is: can I pull off a seamless joint by inserting a pad underneath these floating posts?
My preference is really to keep the basic square bottom on the deck.
What would you guys do here?
So far I've done everything myself and spared no expense in detail and labor to make this beautiful and of high quality. I just put down a mahogany floor. The last thing I want is an ugly seam and the first thing anyone thinks when they look at the porch - "look, a repair!"
Thanks guys, and pardon the long post.
