Agreed, George, but bathwater and babies . . . .
I, finally, went down to the first post, where original posters load info, and found the link for charts that laid info out about the final score.
That said, I did make it through and there was some rock solid info in there that made it worth the whole show. Reminds me of a gal I knew, about 40 some years back. She'd drop a fortune on a seminar, but asserted just one bit of info made the investment, of time and money, worth while.
SIDE NOTE: When I used my Festool Rotex and cyclone to sand the 50 [or so] year old T-111 of our house, I only had to use about five of these for the whole thing. They are Festool creations and run at 36 grit. Perfect for a latex house paint job like I undertook.
