Today I was pretty much at the point where I need to let the stave stay horizontal for a week or so, though I've also kept it that way for a couple days now anyway. However, Before I hold up altogether I decided to take most of the rough (heartwood) off the belly, to preclude splinters in the hands, and allow the moisture content to stabilize, as suggested, easier. I also did a tad more work on the back but only with a scraper. Here are some pics of how she looks now.
The Belly with the majority of the rough heartwood removed (just a bunch of fiberous junk), with light drawknife work and a scraper. Proposed bottom limb at the left in these pics:
I took this picture of the side/edge just to show the depth still left:
Next three pics are of the back, in sections, from left/bottom to right/top after the scraper work - these colors are still baffling me as far as a ring goes, I'm afraid, though I guess it does look a little better:
The brush was under the stave to make it lay level for the pics:
You can see in the center pic that I still have left the handle and fades just marked but not edged, or even scraped any further on the back. Thanks for looking.
