<div dir="ltr"><div><div>All, I am evaluating my K-250 hard hatch/tower ring mating. This hard hatch was custom made for this K-250 by the previous owner. <br><br>When the hatch is closed (w/o-ring removed) and the interior of the sub is brightly lit I notice I can see light between the hatch and hatch ring in places. The "gaps" are not huge and I believe with the o-ring installed no light would be seen.<br>
<br></div>However I believe it tells me there are some flatness issues in this interface. In a perfect world I should see no light.<br><br></div><div>My questions are, what is a precise way to identify the "high points" and is grinding the hatch surface vs. the tower ring the right surface to modify?<br>
