Notes and Changes:
D070332-v6: Changed washers attaching Upper Wire to Upper Mass to Nitronic 60.
D070326-v4: Changed washers on pull screw and between base plate and rotating plate to Nitronic 60.
D070335-v6: Changed SSTL jam/hex nuts on SSTL SHCS to Ag-plated SSTL hex nuts.
D070334-v4: Changed SSTL jam nuts on SSTL SHCS to Ag-plated SSTL hex nuts.
D070337-v7: Corrected orientation of dumbbells (thin section toward mass, away from magnet).
D070308-v3: Changed SSTL jam nuts on SSTL SHCS to Ag-plated SSTL hex nuts.
D080726-v3: Changed SSTL jam nuts on SSTL SHCS to Ag-plated SSTL hex nuts.
D080727-v3: Changed SSTL jam nuts on SSTL SHCS to Ag-plated SSTL hex nuts.
D1102071-v2: Changed washers to Nitronic 60. Changed hex nuts to Ag-plated SSTL. Added separate configuration for earthquake stops below metal mass.
D1001754-v4: Updates based on changes to Upper Mass Assembly and Coil Holder Assembly.
D080677-v4: Changed SSTL jam nuts on SSTL SHCS to Ag-plated SSTL hex nuts. Corrected orientation of BOSEMs to match D1101493-v2.
D080728-v2: Modified to be a two-part earthquake stop for the upper side of the HLTS Bottom Mass to allow for easier and safer optic insertion.
D070354-v2: Modified to be one part of a two-part earthquake stop for the upper side of the HLTS Bottom Mass.
D1200318-v1: Initial release of Earthquake Stop Adapter.
D1102124-v2: Corrected holes to attach clamps from #4-40 tapped holes to #4 clearance holes.
