Another thought regarding steel vs a treated wooden Post. Both should last a 100 years if kept dry and especially moisture wicking up from the floor.
For about $40 more than a PT post you can buy a properly sized steel adjustable lolly column. And what you get is complete adjustability, easier install with the flanges on top and bottom for direct bolting. No shimming.
And will not shrink or expand with humidity changes.
Using wood requires accurate cutting, a separate jack post to install, mounting brackets for top and bottom and if there is compression or settling may require re-jacking and shimming.
Unless your going for a rustic look finished basement I just don't see the reasoning for using a wood post to hold up the house. (IMHO of course) :wink:
just one of several on the market
if I need them I call the factory fist and talk with their tech svc to spec the part number correctly. Then call HD who is a dealer to order, takes about 2 weeks to deliver.^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Sure seems to me YODA has the best idea.... if the standard screw post at the BB stores is insufficient, you can order heavuer duty off the internet....
