Prevent Springback in Bent Laminations
I’m building Adrian Ferrazzutti’s coopered table from “Star Burst Coffee Table,” FWW #225. For the bent-laminated staves, I’m using three layers of ash, with a walnut outer layer, all 1/8 in. thick. After bending, I had issues with springback. Any advice? Would using a softer wood for the inner strips help?

For the laminated staves in my table base, I used four plies, each 1/8 in. thick. I used Titebond II and a form made of chipboard as well as a stack of 1/8-in. strips as cauls. When you get down to thicknesses of 1/8 in. and under, the species of wood is not really a factor—everything will bend at that dimension.
When you glue up, use a lot of clamps and leave the laminations clamped up for 12 hours. After you take the parts off the forms, put them into a holding jig that…
