Here is my new DBA battleboard. It can easily move from 60cm to 66cm to 72cm by removing the inserts. Why 72cm? It still allows 10 elements of heavy infantry to be deployed side by side. Why 66cm? It's halfway between the two!
That's stunning Jim. Love it. Did you do the woodcuts yourself?
It wasn't too difficult.
Base was 75 x 75cm 6mm MDF with Green Marine carpet cut to fit (use any surface really).
Edges were 30x8mm timber measured directly from the board and a single 45 degree cut made with a cheap plastic box mitre. Then file and sandpaper to get the right fit. Finished with maple wood stain.
16mm nails used to secure the outside pieces. I placed them in the centre, 3BW from the centre, 4BW from the edge and 2BW from the edge to help with deployment. The central three are useful in the smaller sizes too. Not sure if I'll mark the inserts as I like the look and don't want to stuff it up.
Finally, some upholstery pins to disguise the ugly nail. These and the stain hide many imperfections!
All with hand tools. Access to a band saw and this would be easily achievable in a few hours
