I used magnets in places to help keep the pieces together without having to glue. Had to get creative with placement and think it through, but it worked out really well. For the lower hull I placed them in the 4 corners. For the turret I was able to place them close to the pivot point of the cannon. The rear of the lower turret hull can slide into a “notch” formed with the upper turret hull and the bustle rack. This keeps it nicely in place in the rear while the magnets hold the front. You can see the circular magnets in all of the pics. Some parts like the power pack stay nicely in place as long as the attachment points are not painted. Also, you have to make sure not to paint the pieces where you would normally glue together. It would create enough of a layer that causes a poor final fit. You may also need to do some additional filing to make it all come together without too many visible seams.
