Favorite, finishing something like a guitar, stringing it up and hearing it come to life, that and planing rough-sawn board smooth. Worst ...Glue...without a doubt. Its where all my disasters occur. I hate gluing. I just had another episode of gluing technique failure. Perfectly fitting joint in a guitar slipped slightly with epoxy, how, I'll never know. Grrr. Can't do much about it! Glue...hate :evil:
BTW, I learned a trick for glue squeeze out. Maybe common knowledge, but I now use a drinking straw cut on an angle so it has a fine point. Run it along the squeeze out (esp in corners) and it picks up the glue inside the straw. Works like magic. Still hate glue though.
