Well, the weather here has gotten really, really cold and windy and with my shop not being heated, it's tough going on the walnut tray. I'm going to just work on it a bit everyday until this cold spell passes.
I just came in after having worked for about 45 minutes. I've cut off two of the corners and begun smoothing the edges with a wood file and a sander. Here is where I'm at:
Here you can see the missing corner. I wanted to follow the curvature of the heartwood a bit instead of just rounding off the corner. And I've beveled the edge just a little with a hand file and sandpaper. I think it looks a little better than it did. I also began sanding it with 120 grit paper:
And this is what it will look like with the handles in place:
Tomorrow I'll finish sanding it with 120 grit paper and move up to 150 grit and I may re-cut the bottom right hand corner a little. Eventually I'll get to 400 grit and this will be on both sides. I also need to get some small rubber feet for it and I'll do that in the next day or so.
