Funny Bill..I personally liked the through tenons with wedges on the "block" trays you didn't even mention
LIKED the "Just because you can, that doesn’t always mean you should..." because being smart/clever can bite you in the b**t often
Liked the Racer one.....must have been fun to watch the kids!!
BUT the most practical tip was "take your calipers to the hardware store when buying dowels"...I learned the hard way!
Enjoyable!!
Thanks!
