Dave and all,

                           Respect your comments re flexplate cracking, and in the process of making anew cushion drive, a cross between  the RWS and mine. Mine in the first batch the rubber did not survive long enough, so the rubber has been upgraded.  The problem still remains that to fix the rubber requires it to be returned to the rubber factory for cleaning and revulcanised.  Then it must once again be trued up on a lathe and balanced.  All time and money and cannot be done in field.

                The new version is a cross between the RWS and mine.  All waiting for the Covid restrictions in OZ to allow work to recommence!  It starts with  3mm chromoly disc bolted to the E shaft, then another cast disc (magnesium alloy for lightness and strength) with 6 rubber doughnuts held to the 3mm drive disc.  According to the experts all I need then is just an alloy internal spline to replace the steel spline block in my unit to drive the redrive input shaft.  This can be cut with a Broach into the centre of the cast alloy plate with the drive rubbers.  A racing gearbox manufacturer tells me that in racing this has held up to 1200 HP.  If I doubt the alloy will not hold the HP I need (350HP and not 1200 HP) I simplly put a S/S collar over the outer of the centre disc where the spline is cut to prevent any chance of the spline opening up.  Probably tells you all nothing, but will have a goods once I get factories working once again.

                This can all be repaired in field (replace rubbers if necessary) so cost and time lost is minimal.

Neil.
