I'd appreciate some advice from someone with more experience than myself (which is most of you): I snagged this piece of pine from a very old house that was demolished down the road from me this summer. I assume it is pine because of how it smells when I cut it, but I guess it could be something else. The board was completely dry, not treated in any way, q-sawn, not sanded, pretty tight grain and a mix of heart and sap wood. As with most old lumber I've found, this is a true 2" by 6" board, no shrinkage here. I cut several 18 to 20 inch pieces, avoiding knots, and left one nice 40+ inch knotless piece in case I wanted to do a neck. I just built my first router table and fence, and used it as a jointer to true up the sides to glue. But while doing this, the heart wood sides of the pieces were so sappy that it started to gum up my newly made router fence on the outfeed side. I've read some posts recently about how tonewood should be harvested in the winter when the tree is dormant to reduce sap, etc. I also don't know how to check the "tap tone". So I don't want want to spend a bunch of time on this only to find out that its dead as a doornail once complete. So is the sap a bad sign? Should I just cut off the heart wood and use the rest?
