I really liked Craig Timmerman's arch bowl demonstration. Great instructions and explanations of why this and not that etc. etc. Never having done one of these, decided to give it a whirl this morning. Here's a couple pics of the results. Kind of satisfied with first attempt but kicking myself for not getting that last ridge out of the arch on the bottom side. Drew a pencil line like he does and got rid of it but could have gone just a touch deeper. Didn't sand anything except for the nub on the bottom. Went by Craig's instruction to start with a blank 7" x 4" x 2". The only thing I'd change would be to make it a little wider so my 3" vacuum chuck would work. Vacuum looks like it would be a little easier to shape the bottom of the bowl better. Don't like how my bowl shape came out. Piece is oak. Anyways, thanks to Craig for sharing.
