Introduction & crankshaft balancer wanted

Hi All:
My name’s Norm and I live near Cairns, FNQ. I’m building an aircraft engine based on a Type-1 crankcase. I’m at the stage where I need to get the crankshaft dynamically balanced.

The crankshaft is slightly different. The pulley end is machined for a propeller hub. It has a 3-degree taper and a keyway. The prop hub has a matching 3-degree taper and keyway. A special long “Pulley bolt” is used to hold the hub in place.

The clutch end has a specially lightened flywheel. Bolted to the centre of the flywheel is a magnetic ring that is part of the alternator and used in the charging system.

The whole thing (hub, crankshaft, flywheel, and magnetic ring) needs to be bolted together to form a unit and dynamically balanced to a high degree of precision.

Is there anyone up in my area (FNQ) that can dynamically balance my crankshaft? Perhaps they have balanced Formulae-V or Porsche racing engines - someone that would put in that extra effort to make it perfect. Any recommendations?

If there is no one up in this area, who would be the closest?

Thanks
Norm
