Dear Daryl,And Im not going to say "my other bother Daryl"Anyway, you are right on track with your thoughts, this sandwich you explain will be fine. With two layers of honeycomb you have to put something in between like you said.I would recommend a urea resin glue for the layup. Not so much moisture trapped inside and the bond is more rigid in the end. I would also press it up all at once except for the final veneer. Also take note that you should turn the vacuum down to around 15 HG for the layup of the honeycomb, then turn it back up for the final veneer pressing. Vacuum can crush the honeycomb to some extent until its glued in place, then it can take full vacuum. I cut honeycomb on the table saw but the bandsaw works fine too.SincerelyDarryl Keil: I am currently making several torshion boxes, measuring 10" deep by 76" wide, to be a total thickness of 2 1/4". Usually I mill : some poplar and then veneer with 1/4" plywood of the appropriate veneer. This gets a bit heavy. I am considering using 2 : layers of 3/4" honeycomb (the type you sell) with 1/4" plywood sandwiched in between, and then 2 outer layers of 1/4" : maple veneered plywood. Can the honeyomb be so layered? Do you recommend doing this in one shot? (I have one of your : vacuum presses). Also, is the honeycomb cut on a tablesaw, and what glue can be used (I generally use white or yellow : glue, depending upon set time. Thanks.
