Last update, I finally got it finished.
Attached File Attached FileI'm happy with it. Wife is happy with it. 4 x $120 (ouch) barstools are on the way.
For anyone keeping score at home, my costs were something like $425 for the lumber and help from a buddy assembling ($125 for him and I have about 1/4 to 1/3 of the lumber left over), $60 in tongue oil (I bought a qt. of oil and a qt. of thinner and still have a lot left over), $170 in pipe, fittings, primer and paint. So if I spent $650ish, if I were able to have cut down some of the waste, assuming that I had all the tools to do it myself, I could have built it for about $450.
As far as time on the top, it was a couple of hours to join, rip and sort pieces, an hour to glue it all up, a couple of hours to run the router sled over it to get it fairly uniform and an hour to run it through a big Grizzly belt sander (that work was all with one helper). Everything else was pretty much me working solo: an hour to trim the ends and make the miter cuts with a circular saw, a few minutes to chamfer all the edges with a router, an hour to finish sanding with a RO sander, then the minor time spent brushing on tongue oil, letting it set, then rubbing it in/off (x 4 coats on each side).
