End of May 2009 / Start of June 2009,
I spent a day driving around Brisbane chatting with various engineering companies about the fabrication of the motor/gearbox shaft coupler and adapter plate.
Many didn't know how to handle the "splined" shaft off the engine to fabricate a suitable coupler.
But I did find 2 companies before long that could help.
Winch Engineering at Rocklea & Extensive Engineering at Capalaba.
As both engineering companies quoted about $1200, I ended up taking the motor, gearbox and clutch plate into Extensive Engineering purely because they were closer to home ...
Hopefully they will have something for me by end of June.
