Hi James, thank you.
Yes I get a lot of comment on the table and mat. Like all good ideas I got this one from what other people were doing. Lord Ashrams blog had a very nice table built around a frame within a frame to lock down the mat he was using over terrain formers.
I simply borrowed his idea and built it, with the help of my son Tom, around my ping pong table. The mat is from Terrain Mat and it locks down under the frame keeping it taught and providing the rolling terrain effect. The base of the table is covered in insulation board.
I soften the contours by putting a felt cloth over the styrene underneath and the insulation boards and foam allow me to pin surface terrain like streams that can easily get moved during play.
It is very adaptable to adding boards for when you need variations in gradient such as when we did Oporto last year. In that case I built the river gorge on boards and raised my mat on the other half of the table to tessellate with it.
All the work on the table together with the construction of each game table is on the blog and you can see what we did. The labels are Wargames Table and Terrain to look up the stuff you want to check out.
I hope that helps
Cheers
JJ
