Thanks Richard, I clamped a steel rule to the marked line and butted up the flat surface of the diamond disc against it as I cut.
Engel have been using this type of lid since their original USS Patrick Henry. I guess if it works don't fix it. If they had a larger lid, then the meatal bars would have to be longer and hence even heavier. If they didn't use metal bars then they risk some of thier customers not securing the bolts properly so it loosens if they over tighten the nut, or stripping a thread off a bolt and not being able to replace it because it is bonded in. Also a larger lid will need many more bolts, and this might put off a lot of customers if it took them 20 min to get their lid on and off everytime. In the manual Engel (are oblidged??) make a point of saying for safety reason the main battery must always be removed from the sub for charging, and if you install any external charging jack or switches the warrenty is immediatley invlidated. So I guess they need to make it easy for customers to take it one and off. I will be installing a quick access/ ventilation hatch so hopefully once I screw the lid down at home I won't need to take it off at pond side at all. I am sure Engel are aware of the limitation of their lid design but the alternative may cause them more problems. Their latest 2 subs now use the bayonet locking system but hence are now devoid of other features like operateable /retractable front planes and working periscopes.
