The depth was a big problem! It forced the upper works (gun house, pan and e-decks) to drop below the top race of the roller bearing where the pan deck should be seated. I had to do a lot of twisting and pushing, but not to hard, since there’s almost nowhere to grab on the model without potentially breaking something. It wasn’t easy getting it in for the aforementioned paint problem. When I inserted the model in the socket, the center column went in too deeply… about a 1/4' or so. I put the bulkhead shells in place so I could gauge the depth of the insertion.
Now that I could turn it all right side up, it was time to mate the model and the base… and it WAS A BEAR! That pesky center column again caused trouble by being painted.
