Summary A large project I did for my tabletop group to play BattleTech. We had problems with both printed maps and hex-sheet setups due to constantly forgetting the terrain that things were on and, later, with terrain pieces getting knocked around the battle mat. This setup uses much larger pieces that normal, roughly 1.25" flat-to-flat. As above, this is a huge project. The hexwall per board above is 42 plates. Hexwall: There's a pattern required to make this work. The pieces will not fit cleanly together; When placing them together the long way (flat ends) they need to placed wide-to-wide and narrow-to-narrow. The gaps will create new hex spaces. There's a picture showing the pattern. They will fit together fine the short way (saw-blade edge) To have a constant number of hexes, this requires an odd number of plates on going the long way. This was designed to have a 2'x3' board fit seven hex plates the long way and six plates the short way. The hexwall pieces labeled end, corners and top are just that. They have a thicker wall and the Top and Corner pieces have an extra spur to make a hex space. When gluing these to a board, I strongly recommend using a T-square to mark of a line 1/2" from the edge of the board and then laying down an entire row against it before moving on. The pieces will wander some no matter what and it's best to do that to minimize it. Do whatever cleaning of the plates is required before gluing. NOTE: If you want to use multiple boards, it's important that they be exactly the same. In other words, I recommend deciding what is your top-left corner and start there each time using the same piece. It's a 50/50 chance how you set things down otherwise and if they're different, they can't be put together cleanly. Pieces: The hexwall and the pieces are under fairly tight tolerances, .06"/1.5mm difference between the total width of the hollows and the width of the pieces. If this is a concern, reducing the pieces by a set percent should solve the issue. Roads, water and deep water are all the same piece. I suggest colour coding and using spray paint if possible. I used: Main board: Light brown/sand with some green Light woods: Moss green Heavy woods: Deep green Water: Blue Deep water: Purple Level 1 and 3 terrain: Grey Level 2 and 4 terrain: Dark brown Roads: Black Woods on fire: Woods piece painted red Rough: Grey, but with the logs painted brown I still use cotton balls for smoke. The top light and heavy woods and the top rough pieces will require supports. I haven't made buildings yet.
