Topic tags/keywords: top glue up

I am working on a buffet table made of Red Oak. After ripping and planning the pieces for the top, each is 1.25” thick, I noticed that one of the pieces stood 1/32 or so proud of the rest, it appears to be warped. Shoud I go ahead an gule up and try to plane this our later, or is there something I should do before glue up?

If you biscut the boards together the biscuts might be able to pull it down into alignment. and if its still a bit off you could hand plane it down or use a belt sander. typicaly i would use the biscuts to try and bring it down then run it through a wide belt sander.

If the board is the same thickness throughout (I check mine with a pair of digital calipers) then it is indeed warped. The warp or cupping can be caused by several factors – internal stress, moisture….etc. Biscuits are excellent for alignment as mentioned above….and would be preferable to just shaving the thickness to match the adjoining boards (if it is stress or moisture causing the warp…the chances are that this board will continue to move and will eventually tear out the glue joint or the adjacent wood). There is a great article on panel glue ups and coopering in Woodsmith (a nice one in the June/July 2010 issue – there are several others also). There are also many You Tubes wideos and articles on this online. Most of all you want to make sure that the boards are similar in grain, cut alighnment and moisture prior to glue up (If I am assembling a panel from woods I acquired over different time frames….I will cut them to shape and let them breathe in my shop for a couple of days prior to assembly….if they have moved significantly during that time….I will adjust them to fit properly and then glue them together (I always use biscuits, dowels or dominos when the panel is thick enough to allow this).
