316ss doughnuts with press in bushes

like other cars, which sometimes get a mention on this forum in other threads about a better way [doughnuts].

im a machinest by trade so it wouldnt be hard to make them up. just a 316SS [or other non rusting material] with the center bored out, 6holes to press bushes into [suitable for the shafts], and 6more smaller holes drilled on a larger PCD to reduce the wieght.

im thinking stainless for strength of the walls where the bush is closest to OD. i dont want to increase the OD too much more than i have to. this is why im not really looking at al'.

i know i have to allow for the flex along the shafts too. how much though? the more flex means the bigger the bushes need to be... which increases OD, and if they get too big, i cant do it at all.
what is the biggest OD i can fit underthere anyway?

ballance will be easy... all diameters will be true to eachother. when set up on the mill for drilling, it will be set up to the center bore within 0.001" . its just the bushes wieght after that.


id rather know what wont work before i try, so flame away!
