The following picture is a typical support under my house. 1950s
construction. This crap is throughout the house. BTW, the previous
owner, responsible for all of this, was successful in the lumber
business. You would think that on JUST ONE support under the house
he could have come up with the money for either a 4"x4" post or maybe
a 6"x6". Heck, he only would have needed an 8 or 10 inch length!!

Ouch.

Speaking of shoring up joists, I may be doing a couple in my extra bedroom
for a heavy thing I am building to put in there. Acquiring/making a slab of
concrete to serve as a base isn't too terribly complicated, but how does one
go about dragging a 50+ pound slab over gravel and visqueen through an 18"
crawlspace to it's intended destination? Maybe a skid or something?
