This is a beautiful piece of spalted maple from eBay. It's also the blank that I made Larry's layout pen from. It was a total pain to turn ...just kept falling apart and then another soft spot would show up. The opening started at 3/4" and ended up at 1 1/2" . I have never done a collar before...but this one needed one. I had some beech that kind of looked like it would complement stuff. Opening on that is 1/2"...just so I'd look cool!! It has an oriental fungus feel to it from the side with the collar lip...or not. I wanted to burn something on it but Steve has my burner 'cause he be da burn King!!! 6x3 with Formby's Tung Oil finish and WoP...maybe 20 coats of each
As always, C&C used.
