Brian,
I am in Kalgoorlie, which is 650 km from Perth. There are only two platers in Perth that I am aware of.
One of them (Kerry at K & D Chrome Plating Services) is excellent, but slow because of the heavy work load. He is the person I always use; terrific with tanks! He has done allof my tanks, and is completing a Super Rocket tank for me, as well as the front & rear guards. The other is quicker, but average.
He would charge around $150 for a rim.
John Berkshire panelbeats and paints all of my tanks, and Kerry does the chroming. John would charge $450 - $650 for a tank, depending apon the amount of panelbeating required.
He has done the tank on my plunger 3 times since 1980.The last time was after the 2004 Toy Run when a middle aged imbecile drove his 4WD in front of the parade and into my left leg!
The caved in tank bears the imprint of my leg (courtesy of his bull bar)!
John did not think he could save the tank, but he did!
Before:
two years later; bike has been re-built and I can walk again!
Ride safe,
Richard
