Re: Clamping wheel hubs

well if the bolts arent in direct contact...

it depends on a lot of things. first of all, the 2 surfaces. if there both plastic then its gonna take more force then steel to get them to stay. if you want it to be pure friction, its gonna be the more torque the better. roughing up one or both surfaces will reduce the amount of torque needed. genraly speaking, if your dealing with metal a half turn past hand tight should be okay for 1/4, a 3/4ths a turn past for 3/16. if its lexan or plexi, your gonna have to be realy torquin down, maybe 2 or 3 turns past hand tight.

but friction can ALWASE slip, especialy if there is an eccesive (and usaly unplaned) force in a parrallell direction to the planes that the friction is acting on (sry a bit confusing). reinfocing with pop rivits or even 1 or 2 roll pins is never a bad idea. hope everything works out.
