Hi benry,

in Europe the rotor heads have gap of 80 mm that can't be easily reduced without changing everything,

I went on machining a rotor head this afternoon, the bearing cage is 62mm large, the it is not easy for me to reduce the gap to the US 63 mm standard .







I don't know the RAF, has he got a 80 gap ?

Great work, very nice!

David

just a try ..

what gap are you referring to?

Hi Jake
GAP= Red double arrow

If thats all your referring to, just machine a hub bar to fit? If you want sport rotors, give them the dimensions of your cradle and tell them to make the hub bar for it....
Hell they made my blades and a custom Hub bar so my blades were longer but still thinner as I requested.
I just don't see that as any kind of obsticle.
But again, I'm no machinist.

this not that I really need a new set of rotors, but I'd like to add a rotor to my collection (((-:
if they are making rotors for the Raf 2000 and that the raf2000 head has the same gap they their rotors should fit my head

as for machining an other hub, is it possible, trouble is that a rotor must be ballanced with the blades on the hub

Just make your bushings the right length and it will be fine.
Remember to leave .003 clearance on the bushing heads

Rotor heads usually have a larger gap than the width of the hub bar and have bushes like Jake said... which you space correctly with shims. When you fit different rotors (with the usual center teeter block) you centralise and space the hub bar with the appropriate shims/spacers

yep ... I could machine two 8.5mm bushings ...
I also think that the teeter bolt has a different diameter then the french one, in france we are using a 12 mm axle

Yup.....there you go.

gosh

Kinda reminds me of those NASA centrifuge things they spin astronauts in.
