build a properly designed deck with concrete fillrd sonotubes to the desired depth, appropriate galvanized fasteners and then appropriate sized posts of your choice of wood. the concrete will last, give greater lateral and vertical strength, so you can replace the temporary wood as necessary.
align the posts and make sure it is perfectly vertical by using a level. once youve ensured the post is plumb, fill the rest of the post hole and double check it with the level to make sure is still plumb. do the same process for all the other posts. these are some more additional tips for securing posts in the ground:

the 6x6 and the double 2x12 are sufficient in themselves for your swing. but the 2x12s may not be attached securely enough to the 6x6 posts, and/or the pergola may not be attached securely enough to the house. also, once the temporary diagonal cross braces on the 6x6 shown in the photo are removed, there may not be enough lateral stability.
common post spacing. in general, the maximum span for a 4-by-6 beam is 6 feet between 4-by-4 posts. if you move up to 4-by-8, you're usually allowed to span up to 10 feet between posts. a 4-by-10 can usually span up to 12 feet between posts. keep in mind that these figures depend on the size and spacing of joists and the overall structural loads.
re: splits and amp; cracks in 6x6 posts 6x6 redwood s4s const. heart run about $8.50 per foot here in ca. since i rarely will use a grade that low, my posts are probably closer to $ 12 per foot. thus we usually use pt posts and add trim. i had one pergola a few years ago where the owner had already purchased his materials.

alternatives for 6x6 posts. in fact, there may be a few advantages. you can select the 2x6s for strength and straightness, then use the best-looking ones on the outside and cut the inner two short to provide a bearing and connection pocket for a double 2-by beam member though dont hide inferior lumber in there; as compression members,
anchoring posts in the ground. align the four sides of the post with the rectangular shape of the pergola, and use a 4-foot level to check whether or not the post is perfectly vertical, or plumb. adjust the post as necessary to make it perfectly plumb. fill the remainder of the post hole with wet concrete, and check again to confirm that the post is square and plumb.
or do we need to install concrete cyliner forms first and lag-bolt the posts to a level surface using a 6x6 anchor. or maybe; just dig out a foot, level, and than place pre fabbed fottings? the pergola is going to be 14x8 and 8ft tall, and it is going to be inches away from the house between the fence and the side of the home standard mega
new design is 3 2x8x16 or 2x10x16 beams one at front and back bolted together and secured on top of 6x6 post. as well as if 2 6x6 vertical support beams will be enough to hold it up, looking for some guidance on mounting a cantilevered two post pergola to an existing 3' raised concrete patio. rough pergola dimensions are 16
lumber size. with 2×6 posts, the girders and cross-members will need to be larger, otherwise the top of the structure will look undersized and anemic. you also have to consider allowable span, based on the size of the pergola youre building. a 12-foot span is much too long for a 2×6 board, for example.
a pergola is supported at the top in both dimensions, so rotation about the base is much less of a concern. for most reinforced concrete, you want at least 2' clearance between the imbedded steel. with the referenced simpson imbed, an 8' dia post base would suffice. the size of the post is irrelevant in this case.

re: supporting a pergola roof on a railing??? it is important that the structure not be able to be blown over by the wind which means it must be properly braced either to the house or to the perimeter piers. a discontinuous vertical support post, even if it is strong enough to take the vertical load, will provide very little if any lateral bracing.
install the post on a new plinth and footing only after the concrete has cured for seven days. wood posts are easier to work with, so stick with wood rather than metal. home centers and lumberyards carry steel mono-posts and steel posts with telescoping sections, but you need special skills and techniques to properly support wood beams with steel posts.
