Hey I'm working on a MOC of The Mole from Thunderbirds in LDD and I need help with a few parts of it like a sliding mechanism for the drill itself and to make the hull round. I've seen a lot of great cylinder techniques that I could use for the hull but all of them were either too fragile, you couldn't make gaps in them for the tracks and sliding mechanism (yes there are tracks on the base as well, take another look) or not hollowed out, which is a problem for me cause I want it to have an interior. also I could use some help with the frames of the chassis and base, not to mention the part with all the crossbars which carries the drill. if you're unfamiliar with what this thing even is then here http://thunderbirds.wikia.com/wiki/The_Mole
EDIT: Also I need help with a sliding door for the interior of The Firefly (another vehicle from Thunderbirds), the wall needs to be like 3 plates thick with the studs hanging off the sides and for the door itself to be 1 plate thick
