Well, got the crud and whatnot ground off of the concrete. Dewalt 18v
4-1/2 inch grinder and cup wheel from Home Despot do a fine job but make
sure you've got lots of battery packs because it goes through them
faster than they charge.
So today I drilled the holes for the sill anchors and rebar (two sill
anchors for each section of wall--one's 4 feet the other's 2 feet) with
rebar in each void space of the blocks. Debated rending an SDS hammer
for 60 bucks from Home Depot or buying one for 90 from Harbor Fright and
went with Harbor Fright--I figured it would do for 9 holes I needed to
dril and I'd have it later if I needed to drill a few more for some
reason. Went with the 10-amp version, comes in a nice case, with a
little tub of grease and a spare set of brushes. I'd never used a real
SDS hammer before and I'm impressed--a while back I drilled three half-
inch holes in that slab with a half-inch hammer drill and it took me
over an hour to do it it. This time it was four 1/2 inch and five 5/8
inch and the HF drilled them about as fast as I can drill studs. Only
complaint I have is that the depth bar doesn't lock very tight and I
ended up going a little deeper on a couple of holes than I intended.
Found out my blow nozzle had walked off so off to Home Despot for a blow
nozzle (HD is enough closer than HF for the gas to make up the
difference)--got the 7 piece kit 18249HOM which has a long tip perfect
for blowing out the holes--got a half-inch pipe brush from the plumbing
department to clean them out--word of advice, if you have both 1/2 and
5/8 holes, do all the 5/8 first--brand new the brush is a tight fit, but
once it's been in a couple of half inch holes it loosens up a lot in the
5/8.
Anyway, got the holes cleaned out, shot the Sika (more advice--keep
pumping it through the nozzle until it turns light gray before you use
it--they say "until it stops streaking" or some such but the dark gray
doesn't show any streaks for a long time and set the rebar and sill
anchors. The first piece of rebar went in with the dark gray, but by
the time I figured out what I'd done it was set anyway, at least enough
that that rebar wasn't coming out without more effort than I wanted to
put into it.
I'd never used a caulking-gun epoxy before. Having read that it took a
lot of effort with the caulking gun and being somewhat arthritic but too
cheap to spend for a powered gun, I did a bit of research and found that
they make guns with up to 26:1 thrust ratio, so I ordered one of those
(Newborn 375-XSP) off of Amazon <

purpose. Sika squeezed out easy as you please with no effort at all.
Gonna be interesting to see how that gun works for other stuff. I
suspect it's going to prove to have been 35 bucks well spent.
