Finished most of the 4mm parts and desided to reinforce the front some more as it will have alot of tension from the tracks.
Have also cut the 10mm bracket for the turret to pivot on.
Weilded it all up and its coming up good, few more bits to make before i can skin the rest of it as I need to make sure i have access int the front and back areas of the hull.

Must thank AWS for the use of there waterjet in cutting this all out
