YG,
–– I just thought I’d throw out my limited experiences just to give you another possible option.
My brother and I went to a professional sign company in Shreveport that can take digital pics and enlarge them up to billboard size.
– My brother chose to do his enlarged gameboard in Black & White and mount it himself. It has several small “wrinkles” all over it although it is usable and we play on it regularly.
– However, I’m “picky”, especially when I don’t want to experience regrets every time I play a game. My first enlarged gameboard was done in color and I had them professionally mount it on a material called “Gatorboard”. It was rather expensive but it’s professional quality is immediately evident. I planned on using this same procedure for an even larger second gameboard that includes enhanced “convoy” symbols and other improvements such as you are working on now.
– I have always planned on custom-building a horizontal “picture frame” type of table that would not only hold this map,….but others underneath the top map, and be covered with a sheet of glass which is countersunk into the table. Although glass might be heavy, expensive, and have the potential of getting broken,…I believe that a sheet of Lucite or other types of transparent sheets would end up being badly scratched up. The “picture frame” gameboard would be also be capable of being mounted vertically on a wall or at an angle in a frame/carriage.
– Anyway, I guess my point is that if we in a small city of 200,000 like Shreveport have access to a professional sign shop,….I can only imagine what capabilities a larger city would have. The only factor to really consider is the expense of having it done by professionals. For me,….it was worth every penny I spent because I’M HAPPY! . :-D
–My experiences may or may not help you,…I just thought I’d throw them out there for you in case they might.
