I'm in the process of planning out a table for some easy living-room gaming. This may be entirely ludicrous.The concept is to start with a small 2' x 4' coffee table to go with my L-couch. Front edge of the couch is 72"x42", so a 2'x4' coffee table is a general good size.The part I'm struggling with is the plan to rotate and fold out the top of the coffee table into a 4'x8' surface.I've modeled and animated the idea in Inventor Fusion, which lands at the extreme end a 2ft overhang from the support layer & I'm certain wishful positive thinking isn't enough to charge ahead with this project & end up with a table that is solid enough for people to lean on it and not have drinks spill.What the amateur mockup leaves out is that the table top is to be mounted on an old ~1928 Ritter hydrolic dentist stand. Chair & the rest of course removed & stored away safely.With 5 layers of wood (lets pretend 'pine') @ 2" thick slabs + any metal hardware would be a respectable ~165lbs (75kg).I'm very much doubting what would be a home-made bearing ring centered on the 1/4 offset of the bottom most layer would reliably hold everything in place, and am trying to come up with a way to trust that I'm not going to be throwing away $500 on trying to build this, only to find out I have to restart & try again with new materials.My present speculation is that at minimum the bottom layer will need to be at least reinforced with metal if not entirely replaced with metal. I have access to aluminum stock, angle iron and the basic required gear to work those materials. Up to an or including coming up with an extra mounting plate that can bolt to the hydrolic base ( ~ 1ft diameter) to give the lowest table layer a larger footprint to connect.Are the recommendations or insights for at least better ways I can go about trying to find the solution to this problem? via /r/DIY http://bit.ly/2UEPUFC
