[PSUBS-MAILIST] axial displacement

[hank pronk via Personal_Submersibles]

Sean, Thank you for the clarification.  I thought that was it, reading the "Hand book of acrylics"  is like reading a different language.  I have got most of it now.  I have an ideal fit meaning there is no difference in the seat angle to the window angle.  My problem is though, no overhang,   my window ends at the end of the window frame.  That is bad!  I can remove the window and machine it thinner by .125 to give me the correct overhang.  I am not sure if it is worth it because my port is grossly over sized.  I will have to study the charts to see how much my window will compress into the seat before I decide what to do.Hank

 With reference to the conical axis, so axial displacement would be the window pushing into the seat. This is why an overhang allowance is necessary.Sean
