help with freestanding deck
 
I want to biuld a deck in my backyard away from my house without having to make it perminent by cementing post in the gound. i want to build something that sits on the ground, but im not sure of the best way to keep it from sinking in the ground and keep it level.

A key factor is the region of the country that you live in.... in terms of cold/frost grade lines.

Here's some useful information to get you started:

I am curious as to why you dont want it cemented in? If you want to move it... I doubt you will really want to go through all the trouble to take it apart. (unless its rather small 75 SQ FT or less) Once you see how much works goes into building one you wont want to take it apart.

deck
 
No problem: Go to Lowes or Home Depot buy yourself as many pre cast 4"x 4" concrete post feet as you need. It might be a good thing to dig a sorta shallow hole where you want each post. Then fill the hole level with #2B stone. This allows for the water to drain away from the immediate area below the post foot so when the ground freezes and lifts the stone absorbs the the heave and makes leveling the feet and plumbing the posts much easier. Cut the post off to a tad longer than you need, Drive them into the post foot with a "BMFH" (sledge hammer). Attach the joists. cut the posts off level to the joist. Attach the deck boards. Pop a beer and kick backl.

If the post already drive into the foot... How do you cut them easily consider you need to make the joist level... so every 1/8 inches count... what tool do you use? consider the post are very thick/large... circular saw may not be deep enough to drive for one clean cut....Just curious... shouldn't it measure and precise cut before driving in the post into the foot? or there are those large jag saw can be used to do this...

cut off posts
 
Never considered that one would attempt to build a deck and not understand how to cut the posts off. Anyway to your first question, You use a level to set the stringer joists. Those that go around the perimiter. and or attach to the posts. Use lag screws for that 3/8" - 5/16" X 3" - 3 1/2" predrill the holes in the joists. Use washers if you think you are going to disassemble it sometime. Then to cut off the posts, my tool of choice is my sawzall with 10" demo blade. I have used a chain saw as well, both electric and gas. a regular old hand saw does a fine job. And don't make it too difficult. You are not building a peice of furniture....an 1/8" on a deck is nothing even an inch is not noticable. but don't get sloppy.
Good idea to buy a book at Lowes "How to build a deck". $15.00 money well spent

cool... that is nice.... got the idea... I think I do... I sure will read book before actually doing it... but would be nice to get a taste of how to do it even before digging into reading....

I was thinking of cutting a free standing post... that is why I think it is odd....

more cut off
 
The thing about cutting the post to exact length prior to setting the foot on the ground and driving the post into the foot, (by the way, take a hatchet and knock the sharp corners off the post where it fits into the foot. that will allow it to drive in deeper) You will never know how deep you are going to get the post to drive into the foot. They fit very tight and since you are not likely to use a transit and set the post foot at exactly the same elevation they will all sit at a different elevation particularly if your ground has any slope to it.
By the way, are you the same guy who is finishing the basement?

Yes.... I am... got 5 or 6 more baseborad done before it got completed... but 1 minute final inspection already done by the inspector...
