I am making ceiling panels ( 42 1/2L x 23W ) out of 3/8 thick x 2 1/2 wide
alder wood. My first 'test' panel worked fine and I used biscuits about
My question is...if I eliminate the biscuits (time savings) and just edge
glue the 3/8" stock using stabdard bar clamps...will I have any type of
separation problems down the road ?
For this application..it's fine if there is a slight unevenness to the
joints here and there...using knotty/rustic alder and want a kind of rustic
effect in the room
Nope. Not as a result of omitting the biscuits, anyway. As long as your stock
is properly surfaced, and your gluing and clamping are done properly, you'll
be fine. In edge-glued joints, biscuits aid in alignment, but don't add
significantlly to the strength of the joint (which, with modern glues, is
stronger than the wood to begin with).
Unevenness *will* weaken the joint -- biscuits or not.

If it ain't broke, don't fix it.
It is debatable whether biscuits add ant strength. I have made 18"
wide panels 1/4" thick for scroll sawing and never had separation
problems. If properly prepared glue joints are stronger than the
