Oy!  So Steve, is this one of those things that can't be done?  I
don't *know* how I'm going to do it.

Off the top of my head, where vague thoughts have been fluttering like
bats...

   Drill 4 holes straight through 6" of floor.

   Rent a lightweight air hammer and cut out the plug, maybe 1 or 2
   inches oversize.

   Gouge out some of the compacted fill underneath a bit wider than
   the hole.

   Make a steel sleeve from 1/4" plate to accept the 4" HSS post.

   Vibrate some cement into the hole, up to the underside of the
   existing floor.

   Put the sleeve in place and fill around it with pour-rock or
   similar product.

I can think of variations.  E.g., the sleeve has a bottom with a 1"
hole.  Drive a 1" stake down through the hole as far as possible and
then weld the stake into the sleeve bottom.  Um.. 4 such stakes?
Um...or a couple of strips of 1/2"x1-1/2" that are longer than the
hole is wide [1]; get them in place under the floor and set into the
fresh concrete leaving a 1" gap.  Weld them to the sleeve and put the
stake down between them. Um....

I dunno [2].  If you've tried this and it didn't work, what should I
not do?


BTW, I was using the big vise tonight for the firt time.  Forging a
gargoyle doorknob on the end of 2" round.  The workpiece never moved.
The screw is a litle sticky when tight but I suspect it will wear in
after a while.

[1] Why are manholes round?

[2] Dang, where is Bugs Bunny and his portable holes when you need him?
