[PSUBS-MAILIST] conical fit

[hank pronk via Personal_Submersibles]

Okay it was me and not my lathe ;-(   After painstakingly setting the hatch up in the lathe with a dial gauge I found where I went wrong.  I set the angle with a very high degree of accuracy and re-checked the angle after locking the the slide down.  I discovered the angle changed significantly from the lock down process.  That is why I was having trouble.  The hatch fits as perfect as I can detect now, Whew!  Hank
