Had a little problem with my DO curing. After 5 days at 65-70 degrees and 12 hours in an 85 degree room I was still noticing a very small amount of wet oil on the sap wood. After doing some reading I took the table top out for some time in the sun. It was amazing the amount and speed with which oil started running out of the pores. These photos were taken after only 30 minutes in the sun, and only 65 degrees outside. Hopefully a day of sun exposure will finish curing/drawing out any remaining wet oil.

Second problem this piece is full of cracks. About 6 months ago I started preparing this project by filling all the small cracks and knot holes with Syatem 3 epoxy dyed to match the walnut color. Then after 6 months in my shop and no movement from any of my cracks I decided it was stable enough to start working. After many mistakes in the shop, and a lot of time with a belt sander erasing those mistakes I sanded through the epoxy that was in the smallest crack, and not the crack is opening up just a hair. I didnt even notice that I had sanded through the epoxy in the crack until today when I was wiping the oil off and I felt the difference. After some close examination I think that I will have to do something more than re epoxy. The crack is just too small for the epoxy to get down deep. I think I flip it over and route some 1/4 inch wide 1 inch long and 1 inch deep notches along the crack and put some homemade walnut dominos in. I wish I had that fancy festoon domino machine right about now.

Hopefully these hiccups will help me learn for my next project. If anyone has any tips or thoughts on these two problems I’d love to hear them!

Before posting this I took a closer look to see if there were any more problems. And yes, there are several new hairline cracks, and one of the cracks I had previously filled with epoxy has opened a little bit. I think that the sun beating down of the dark oiled surface may have gotten it too hot and caused me a major headache. I think that in addition to adding some ‘dominos’ to the bottom along the crack lines I will re epoxy all the cracks, only this time I will do it outside on a hot day and with heated epoxy to help it flow as deep as possible. Has anyone ever tried using a syringe and needle to get a wood filler, glue, or epoxy down into a small crack? If so do you recommend it for my situation?
