This has saved me loads of work. I would have had to make the layout myself, otherwise.
I plan to build my pit quite similar to what Mark has rigged up for himself. However, since, 'portability' of the pit is one of the key criteria for me, I will have to use thinner wood panels to keep the overall weight down.
I also plan to break the pit down into four "pieces" for ease of transportation (ejection seat, left console, right console and front instrument panel).
