I am building a table top using your honeycomb product. I will be using 3/4" honeycomb with 1/4" medex skins for an overall thickness of 1 1/4". Is it still necessary to glue a balance veneer to the bottom of the table when the core is a torsion box type of arrangement?

Tom,

I recommend veneer both sides of your torsion box. You didnt say how large the finished size will be but veneering one side will put unbalanced stress on you panel. For all the work you will put into constructing the torsion box the insurance of veneering both sides is well worth it in my opinion.

Sincerely
Darryl Keil

Thanks Darryl. I had planned to do both sides but saw an article in FWW that appeared to have only one side veneered and was just wondering what the recommended process was. Paul Schurch recommended your honeycomb product so I am going to give it a shot.

I want to construct a torsion box approx. 4ft x 5ft, thick enought to retain flatness as a desktop surface for layout and assembly of light furniture projects. I want to try using insulating foam sheet for the interior and probably vinyl coated MDF for the skin. Need reliable recommendation for adhesive and foam thickness suggestions. Thanks

Bruce,

As far as glue goes I recommend a polyurethane glue. There is Gorilla brand polyurethane as well as one from Titebond and Elmers.

About the foam thickness. I have not used rigid foam for a torsion box core so I cannot recommend a thickness.

As stated before, I also suggest veneering both sides.

Sincerely
Darryl Keil

Hi, I too have been researching the construction of a torsion box for use as a dead-flat assembly table in my shop. David Marks did an episode of his tv show on building a torsion box assembly table, but the reference to your resin impregnated honeycomb product in Kim Carleton Graves "Dining Tables" book got me thinking beyond dozens of small pieces of mdf to accomplish the task!

I also stumbled upon the website for Nidacore in my search, as is suggested elsewhere in this forum. (I have requested more info from them, but haven't received it yet.)

Darryl, do the panels you sell come in larger sizes? How difficult would it be to layout and press a larger panel from the 2x4' pieces if my goal is a dead-flat assembly table?

William,

You can press up any size table with the 2x4 size honeycomb we carry. Honeycomb offers no strength edge to edge. It comes only from surface to surface bonding. We sell it in 2x4 sheets as this makes it practical to ship by UPS.

Sincerely
Darryl Keil
