Thanks a ton ya'll,
Capt. Caveman, TY for the "english" word.... You got to remember I am from Arkansas... I don't know these things...
djmodels1999 You are right, and I thought about that for a bit, but concluded the suspension would have some amount of droop but not that much because of the very high spring tension.. But even so the tank will be eventually completely submerged, so decided it wasn't worth the effort since it won't be noticable in the end.
So far I have about 30 min work in the diorama. I should make so progress this weekend.
Thanks again ya'll I'll keep ya posted.
