Thanks for the links and the video. I had seen some of that info before, but never collected in one article like that first link. I still haven't read the second link. Bud; the video is very helpful in helping me realize that unless I can pull together a couple of hefty neighbors, that is probably not a DIY for me. I can do a lot, but the self leveling pour is so time sensitive that working solo or with just one guy won't be smart. As much as the good ol' days sounds like it should be, I know that grabbing neighbors is tough these days, and I don't think any of my old friends would be up for a job like this.
I brought in a pro to give me an estimate and he thought that by the time he was finished grinding, the floor wouldn't be too bad. I will (of course) get another opinion, but maybe I'll get lucky enough on this one.
