I'd like to take a survey.
The client wants a 30" round table top 3/4" thick with a solid edge routed with an ogee bit. An octagon MDF substrate has eight pieces of solid mahogany about 2" wide glued on to the edges and then a 30" circle has been cut using a template. The solid wood edge is .5" at the thinnest part of the edge and about 1.5" at the widest. Both sides are sent through a wide belt sander so the piece is flat.
You now are getting ready for gluing up 1/42" veneer top and underside balancer. Assume urea glue is being used.
Question #1. You would do a:
A) 1 ply top and 1 ply bottom (same time).
B) 2 ply top and 2 ply bottom, adding each layer to the substrate in 2 glue ups.
C) 2 ply top and 2 ply bottom, gluing up the veneer plies in the first step (rotated 90 degrees of course), then gluing the 2 ply front and 2 ply back to the substrate in a second glue up.
D) 2 ply top and 1 ply bottom, gluing first ply of front and back at the same time, then secondly just the additional ply top last.
E) 2 ply top and 1 ply bottom, first step gluing up the 2 ply top, second step gluing the 2 ply top and backer to the substrate.
Question #2. You're doing another top with a solid oak edge instead of mahogany. (Oak has twice as much seasonal movement compared to mahogany.) Would your answer change?
