Well, I am getting there.

After a little geo engineering,  a bit of practice, and some crawling around, I was able to get the tool in there to both my, and the task's, satisfaction.  I was not able to find my chalk line, but that is on the way.  When I do I will have a simple task of creating a line and removing, perhaps, an inch off the top.  Right, but I got the bulk of it done.  I simply need to fine tune the job.

I found a face mask, but it was terrible.  It had two elastic bands, one of which broke while initially donning the thing.  Then the thing would not truly fit on my nose and over my chin both at the same time.  After only a minute or two of fussing with it while trying to work, the other band broke.  *cough, cough cough, cough*  I simply could not work without something.  Hmm... maybe some low-tech?  A bandanna?  Would IT fit.  I bought the biggest ones I could find, and I can't remember if I tried them.  Oh, but it would have to be wet, or that dry dust would get through.

Perfect!  Mostly.  I was just able to tie the very tips of the square.  Good enough though.  And, wetted, it kept the dust better than the shot mask ever had.  Back to it.  After cutting what I could, as straight as I could, I did the clean up.  Dry dust, parts of drywall, bits of wood and plaster from the old wall behind it.  I removed the screws I found, dug down into the basin around the wall, swept and plucked and got it cleaned.  Nice.

Then I finally finished that load of dishes.  All is dry, most of it is put up.  Next, after I rest a bit, a shower.  That wore me out more than I thought it would.  Stooping, don't you know?  Both for the dishes and for cutting the base drywall, and getting the oscillating saw in amongst the pipes and toilet and all.  I put a replacement pot of tea on when I finished... just...  I keep four in the fridge.  I try to keep them full.  Rotate.  This will be an extra pot of tea, for when I finish the next half gallon jug.  I like to be ahead.

Yeah, rest, then paperwork.  I don't know after that.  I wanted a nap.  Maybe after the paperwork?  Maybe.  Later.
