I am building a headboard that requires an arched border along the top
edge. The border is 3 1/2 inches tall (the side that faces outward)
and 1 1/2 inches thick (top edge). So it's not the type of arc that
can be bent.
My plan was to piece 5 wide straight segments together with angled
joints then cut the arc from this. The segments would be 22" long for
the center and 2 14" segments on each side. I started worrying,
however about the integrity of the joints. First, they would be end
grain to end grain - I could do a lap joint or a dado to help with
that (I don't think biscuits would be enough). Second, I was worried
about the wood movement. As the segments swelled, on the convex side
of the arc the joints would grow apart, and on the concave side they
would push toward each other. I thought this might make the joint
Does anyone have experience with something like this? Is there any
other way to do it? Should I have smaller segments between joints?
Is there enough movement in 3 1/2 inches to cause any problems?
This is my first commissioned piece for someone else, so I really want
to get it right.
Thanks for any advice you can give.
