  1. TKR Flexure Shoulder Bolt TKR Flexure Grid Shoulder Bolt (close fit) Grid Collar/Pin with conical head (pressed in) Conical Bushing TKR-Grid I/F Design Options 2 1 Light pressed pin takes all shear load. Bolt simply holds pin in place. Need to work out method for extraction

  2. TKR-Grid I/F Design Options Shoulder bolt TKR Flexure TKR Flexure Custom Shoulder Bolt with tapered end (close fit) Grid Shoulder insert (close fit) Grid Grid 3 Tapered split rings to expand radially under axial compression Constant Force Washer 4

  3. TKR-Grid I/F Design Options (fastener locking) • Lock wire • Key insert • Set screw • Liquid Shim on shoulder • “Battery terminal” on side flexures • Urelane (loc-tite) threads

  4. TKR-Grid I/F Design Options (key decision) • Conical bushing (concept 1) favored for corner flexures • Issue: Imparted loads due to enforced displacement – need to look into maximum allowable enforced skew of TKR bottom tray • Issue: imparted hoop stressed in flexure • Action for Tom Borden: how to modify tooling to put conic into existing flexures (enough room for taper?) • Action – ensure taper is not a self-locking taper • Action – check loads on flexure and bottom tray • Liquid Shim at side flexures (zero tolerance plus positive locking) – need to ream existing holes to achieve 0.030 clearance or grind down shoulder, plus injection port, split washer, etc. • Action – Martin to talk with Rob Black regarding injection and liquid shim 0.551”

  5. TKR-EM Tower Path to Re-vib (T. Venator) • Grid I/F redesign concept • Define concept • Define Schedule • New Vib Plates • Flexure tray I/F analysis redesign? • Analysis of all tower fastener torques and locking features • Resolve sidewall design options • 120 degree fastener heads • Mid tray mods, etc.
