I thought I'd pick everyone's brain for this...
I got a piece of Juniper last week and turned it right away (I don't know how seasoned it was when I got it). It did not seem too wet or resinous. There were some end grain cracks starting to show on the outside as I was hollowing the inside (in restrospect, I should have either continually wet the outside, or maybe covered it with saran wrap to keep it from drying out too quickly). So I sanded the outside to 220, let the sawdust fill in the little cracks, then put CA glue in the cracks. Then fearing that the CA glue would discolor around the cracks, I decided to put CA glue around the whole outside of the form. I finished hollowing it and then brought it inside to let it dry a little more. I weighed it every day for about 4 days and there was very little weight change, so I figured it was pretty stable. Two days ago, I decided to finish it. I started at 220 grit, followed by 320, then 400. I sanded the inside too to 400. Then I decided to use my most recent favorite finish, Formby's Tung Oil finish. I figured I had already sanded past whatever CA layer there was, so the Formby's should absorb pretty easily. And it did. The wood practically soaked it up like a sponge. Now, though (two days later), there are still tacky parts. I'm used to Formby's being dry in about three hours (though I always allow at least 12 hours between coats). I'm in Southern California where it has not been particularly humid lately.
Any ideas why it's still tacky and what I should do?
Could the tackiness be:
1) my Formby's it getting old and I need to throw it out?
2) Juniper is more oily than I thought?
3) the CA glue is causing a barrier in parts?
What should I do:
1) be patience and give it another week?
2) strip off the tacky parts with mineral spirits, laquer thinner, or DNA?
3) sand it all back down and start with something else.
