Going through the pile of firewood again and an old piece of oak caught my eye. This was a severely cracked piece with the beginnings of dry rot pitting. Had some good success rescuing wood like this in the past, so I thought I’d give it a go.
Didn’t take a photo 'before epoxy, but here’s the start point before cutting:
These cracks extended all the way through, so I just used multiple layers of packing tape around the edges to seal the epoxy pour.
After the rough cutting, the dry rot really began to show, so I brushed on a coat of epoxy before the finish cutting in an attempt to seal those flaws:
That did work fairly well, but after the finish pass a lot of discoloration did show through:
The white spots, which is the dry rot, were now hardened from the epoxy, so I pressed on with multiple polyurethane finish coats with light sanding between each, with a very satisfying result:
The finished bowl is just about 9" X 10" X 3". The design and toolpaths were done with Vectric Aspire, still learning Fusion toolpaths, sigh.
