Hey All,
Running into a predicament, a friend of mine wanted desk made from redwood planks from the local bigbox with some really nice figured grain. We took it, planed it, and glued up the lumber to form a nice desktop. The issue I'm running into is on the sanding, I literally sand and sand and sand, a few hours later ill come out to the garage and the figured grain itself is raised every so slightly, giving everything that just 'slightly bumpy feel'. This is only where the grain gets intricate, the straight grain stays nice and smooth. I've thought about just going at it with as sharp as possible smoothing plane to see if itl help. It's just odd because it feels smooth, a few hours later its raised again, makes me wonder how dried this lumber really was or if the humidity around my house is just changing that much to have that much of an interaction with the wood. I myself really primarily work with walnut,maple,oak and anything I've ever built with pine is usually garage type stuff so i just haven't paid attention this closely to these types of materials when trying to get more in-house furniture quality.
Just wanted to get some thoughts from you folks with more experience with me.
