1st - I finally found my original post on this subject! I hereby Necromance my own topic with ontopic content and shame myself for my lack of updates on the matter until now!
2nd - I have updates!
I have built something of a monstrosity. like most rewarding endeavors full of trial and tribulation, I do not recommend you follow in my footsteps!
the first table i build is actually 2 tables. each is 4'x4' made to fold in half. these tables are butted up to one another to make a 4'x8' table. this was an old table standard from eons past. i plan on hosting a lot of big games and i felt i needed the space. also when playing a "normal" 4'x6' game the table provides a 1'x4' unused area on either end that has been quite handy in the 2 games we have already played on it.
the large double table is extremely sturdy. a friend and i both stood on one of the 4'x4' sub tables at the fold seam and it barely budged. essentially just the minimal flex of the lumber. this was over 400lbs of mankind. So unless we all switch back to caste lead miniatures i think we will be fine!
the table was a little rough and i ended up adding some bolts to pull the 2 halves together so they couldn't be bumped during play. my 4'x8' table is meant to stay set up long term but is fairly easy for a handy person to collapse and store. very important since i HAVE to sell my house for budget reasons and i will also be moving several states away for family reasons.
I have worked out a "better" design for my second table. it will be a 4'x6' table. the table will fold into a 4'x3'xdepth section for portability and stowability. the legs will also fold into the frame. so essentially there will be NO disassembly and reassembly required. this 4x6 table is to be a gift for my brother on his birthday feb 2nd 2020. so you will see this thing build very soon! the necessary material and tools are already in my workspace.
i have worked out how i will build the modular terrain for both my table and the 4x6 table they will be in 2'x2' sections like the GW boards. essentially cutting out a topo-map in 1/2" thick OSB to be laminated in layers building the rough of the terrain. wood fill and sculpted to finish the shape then the usual detritus and painting etc.
anyways. i am resizing pictures now. will post shortly
