MD has a Honduran RW back with spruce lattice bracing. Center strip is a 1" wide spruce cross grain. Center strip gluing is a tricky work, because the center strip slips due to the glue's viscosity. If minimize the apply amount of the glue, it will create glue voids. If it applies too much, it creates a slipping problem. To avoid the issue, I have been using vacuum clumping technique. Vacuum clumping does not show the slipping issue, no matter what amount of glue is applied. I apply, more than enough glue. After 7-minits of clumping, I remove the back, and remove excess glue. Then, put the back into the vacuum bag, and takes 20minits more vacuum clumping.
I also cut back bracing wood from Adirondack spruce logs. Lattice pattern is completed. Lattice brace has 12' radius doming. Lattice brace is almost ready to install the back.
