I tend to be a stain after glue person. There are only three instances where I will stain/finish first.
(1) When the project size would be hard to handle if it were stained/finished after glue up. Case in point is the set four almost eight foot tall bookshelves I am working on right now. I will be bursting at the seams in the shop until I can get the carcases in the house. I could not imagine trying to maneuver these monsters around for staining and finishing in my shop after they were assembled.
(2) When I don’t want one piece to stick to another. I there is a situation where I absolutely do not want one piece to stick to another piece, I will stain/finish first. The most often seen case of this is a solid wood panel in a frame and panel situation.
(3) When the look of the finished product may be jeopardized. This again is the case with frame and panel construction. I will almost always finish the panels before inserting them into the frames so when the contract with humidity changes I do not get a line where the finish ends.
Other than these situations, I much prefer stain/finish after I glue.
