I need to make a curved apron for a table. I was planning on laminating
wood to form a curve with a 48" inside radius. How much spring back can
I expect and how should I adjust my bending form to account for spring back?
Spring back will be reduced as you add the number of pieces. With 4-5
pieces you will only experience very little spring back.
Hint: Use a slow setting glue, build both the negative form and a positive
one as well, clamp well. I did neither with the last project. It was a
I just made some cabinet doors with a radius of 17 inches. My
laminations were from 1/8 inch "bending" plywood which is very flexible
in one direction. I also used a urea formaldehyde glue called Unibond
800. When this glue dries it is completly ridgid. If you use a yellow
glue and if you're bending stiff wood, I would expect springback and it
might continue to spring back over a long period of time. With the
bending plywood, you will need to apply a veneer.

If you use several layers you won't see a whole lot of spring back. I
wouldn't worry too much about it as long as you have a good way to
attach the apron to the table. You should be able to spring it back
where you need it as you secure it to the table top.
My only suggestion would be that if you're making it in two halves
make your jig a little bit more than half the circle. That way you
can cut the ends where you need them and still have the bend at the
