John asked me to corroborate with him on the display stand for the 2011 March of Dimes knife. He also asked me to do some snapshots along the way since this is a WIP thread.
We decided I would provide the base with some sort of mosaics in it so I thought a mosaic name placard would be nice. I realize I'm "making the box for the piano and not the piano" but I hope you enjoy it anyway.
I started by cutting some diagonal spalted birch slabs on the band mill and picking out the nicest one.
Here I have laid out the rough oval shape we want to use, it's roughly 15 inches by 8 inches and 2 inches thick.
Here I've cut out the oval and used blue masking tape to form a barrier to contain some casting resin to stabilize the slab. Since spalted birch is very near rotten, it is necessary to stabilize it. I'm using West Systems clear casting resin; it hardens up harder than epoxy, absorbs into wood very well and finishes up real nice. It's hard to get a good finish on epoxy. I mixed up a cup at a time of the resin and poured it on, when the first cup was mostly absorbed I poured on some more. Spalted birch is like a sponge, I used two cups on the top. When the top was curing well, after about eight hours, flipped it over and did the same thing on the bottom.
After waiting three days for the resin to cure up hard I sanded it good and flat and rounded the corners over with the router. Then I sanded it to 320 grit. The finish size is about 14 X 7 1/2 X 1 3/4.
Here it is after the first "flooding" of the surface with pure tung oil. The wood is still pretty thirsty, even after stabilizing so the pure tung oil, being thicker, will take fewer coats to seal it up. I am doing the bottom too, to insure against warping. I can switch to another oil if I think I need to after two or three coats of this. The oil needs a day between coats to cure so you really need to plan ahead on a job like this if you have a deadline, like I do

In the mean time I can start on the name placard.
