I'm pretty sure I didn't glue mine in either . the mast's do go through 4 deck layer's , pretty much no room for them to go anywhere . I also did as GM said and each deck layer the extra styrene got smaller , around the gun port's . very happy with the effect .
don , how do you put what someone else has said into your post . I think you have told me before , but I,ve forgotten , getting old
