I am speaking specifically about the glue lines in glued up tops. Sometimes it seems as if how well you saw it, joint it, re-enforce it with mortis, tennons, biscuits, or splines it still has the ability to do what it wants to do. This morning I was able to continue putting my latest lid together. I last worked on it about 2 weeks ago when I ran the two pieces through the jointer and had to stop for the night. This morning after putting the two pieces together again I noticed a gap in the middle. Guess what? Back through the jointer I had to go. The darn stuff moves on you when your are not looking. So far I have noticed that no matter how well you plane to equal thicknesses or carefully rout out the biscuit slots things can still change on you and you wind up having to sand it to level. Woodworking is a big aggravation to my wits but I think that is the very thing that draws me to it. It not only is superior to my skill and intellect but can be tricky so you have to be on guard all the time when working with it. It challenges me on all levels but when I get done and the project is completed I can think to myself that I overcame all that was against me and I fought the battle to victory. LONG LIVE WOOD. Actually, I am of the opinion that wood can crack even though it may be screwed or glued to where it may be immovable; darndest thing that wood!
