I bought the Dragon USS Maryland + USS Chicago because I wanted to try a 1:350 ohio class sub. I’m having problems with the hull lining up though. It seems like no matter how I position the halves there is an overlap or lip on one side or the other. I’m wondering how other people deal with this? I could sand it down but it runs the entire length of the sub and I would sand out quite a bit of the body lines. I could, of course, scribe those back in after I’m done though.
Go ahead & sand the overlap down & make the hull round. You need to fill in those “engraved panel line” trenches on the Dragon/DML hull anyway.
Trident subs were constructed by stacking together pre-assembled hull section rings. That is what the trenches are supposed to represent. However the tolerances between the rings were 1/8-inch or less. That is 0.000357 inch at 1:350 scale. Fill and sand
You might also look into creating “spreaders” with spare pieces of sprue to push into the half that is narrower than the other. I personally find this more effort than just filling and sanding the steps on this particular kit, but some kits almost require this due to mold miss-matches.
