    Need Help Designing Large Table

    I need to put together a design/bid for a large conference table. It will be about 4' by 8' with a boat-shaped top and trestle-style legs. The customer wants a formica top with oak banding, legs and stringer.

    I'm in the 'design' process and am having a hard time wrapping my head around the idea of how to get the necessary structural rigidity and flatness to the top, which I am assuming I will do with the formica laminated to MDF. Should I be looking to some sort of torsion box design? Please help!

    jon, most wholesalers offer honeycombed substraight material just for this purpose in sheets up to 5x12........i don`t consider it to be a "high quality" product.....but for laminating formica it works pretty well.....you`d need to build your frame and use the honeycomb as a fill then laminate both sides but it makes a light, stable top.......if you go with mdf you`ll need to provide some way to keep it flat.....either with some type of frame underneath or by laminating both sides or both........by trestel are you talking about a 72"x24" pedestal or a single 16" diameter post? how thick can your top be? the base and top thickness are your major limiting factors......that and when building conference tables i try to make them where folks can sit on the edge without damaging the table......it happens .....tod

    What I would do...

    1 1/8" 45 lb density particle board laminated with plam both sides or plam and backer with urea resin glue, this is very stiff.

    Does a 1 piece 4x8 top clear all the doorways stairs elevators and what have you? I'd assemble the trestle on site.

    Good luck!

    Thanks for the good advice guys. The honeycomb idea is interesting, Tod. Do you have any brand names of this stuff that might help in my search? Thanks...Jon
