Well, hell! That doesn't seem so tough! (Thank you Matt!) The wiki article tells you exactly how to make it. I quote...(
Wiki source Quoted Text
The typical Marsden matting was the M8 landing mat. A single piece weighed about 66 pounds and was 10 feet (3.0 m) long by 15 inches (380 mm) wide. The hole pattern for the sheet was 3 holes wide by 29 holes long resulting in 87 holes per mat.
Break out some aluminum flashing, cut to size, add holes. Or, maybe some .020 sheet/stripstock, again, cut to size with holes added. You probably don't have to go 29 holes long exactly, but, make the first one and use it as a template for many more.
Hope this helps,
