Basement Jack Post's Wood or Metal?

be replaced. I'd like to get ideas regarding the placement of them and
the size of the. The house is a 100 yr. old. 1,200 sq.ft house, rock
wall foundation. I want to use 6 x 6's and some post jacks too. Can I
place an 8 in. concrete section above the floor, encapsulate the 6 x 6
and run it to the beam as you would with a floor jack or, simply use a
30 ton jack or so on top of the concrete floor? The beam going across is
wood, and I want to firm that up.
I'm recuperating with 7 stitches and two crushed bones in my finger
in the meantime and need something to do. (Helping my friend with some
post digging and slammed it into a pipe). Ouch!
Thanks in advance and work safely!

I did the same to my 100 y/o house two weeks ago. However, I decided
that since I was doing the posts and this was a part of a basement
renovation that I would replace the 8x8 wood beam as well. I used
steel all around, including an 8" I-beam and concrete filled steel
posts. Reason #1: basements are generally damp and this is termite
country. Reason #2: by using a steel I-beam I was able to get rid of
one support column and relocate another to a less obstructive
location.
However, if you just want to replace the posts, I'll ACK what Dan
Hicks said: go with a screw jack lally column. They're very easy to
work with. If you have doubts as to the footings, get a 1/2" steel
plate, between 12" and 16" square.

Unless you're really hung up with wood, I'd use metal lally columns.
You can order them to the exact length within 2-3" with a screw jack on
one end. If you simply replace the wood posts one for one you shouldn't
need any further footing or anything (if it holds the wood it should
hold the metal, provided you use something on the bottom to spread the
load a bit). If you want to add more posts then you in theory need
footings for the new ones, but you probably don't need much with the
number of columns you're talking about.

I only want to replace the posts not the beams. Should I dig the posts in
to an eight inch concrete block or such?

(such as they are) do not seem to be failing, there should be no need to
install new footings. With a wood beam you likely have two or three
times as many posts as with a metal or engineered lumber beam, and hence
the force on each post (and footing) is much less. You do want to make
sure the force of the new post is spread out over the entire face of the
existing footing. This can be done with a doubled 2x block (with the
two layers at right angles), a heavy (1/2") metal plate, or a pyramid
block.
