I just started a build thread in the Kit Building forum for a Tiger 60.  As usual I like to read whats goin on in several forums so thats why I am here.   And I am glad I read this thread.  I am planning on building an enclosed nose cowl for my Tiger and I wanted to use an aluminum spinner.  I never thought about having to modify the spinner to fit the prop since I have been using a spinner nut on my trainer.  That being said, are aluminum spinners made to fit specific props?  I cant imagine modifying an aluminum spinner with my dremel.
