I"ve found a bloke who knows what he"s doing and who is experienced with "exotic" materials. I said I"d post his details here after he gave me a hand to fix some rotor head componentsHis name is Phil Greengates, his business is "Rich Engineering" and he has a machinist"s shed full of lathes and mills. He works on the Maxi-yachts such as Wild Oats & other boats that do the Syd-Hobart races. He"s demonstrated quite some speed in doing my job for me & was reasonably priced.Rich Engineering Pty Ltd Erina2/14 Aston Road, Erina NSW 2250(02) 4367 0792Please, don"t **** him around with tyre kicking enquiries, that is how "good guys" are lost. If you have a job, send proper engineering drawings to him for pricing. If you don"t have proper engineering drawings I may be able to help.
