could this be a 'shoulder bolt' or stepped bolt' ,the 'rose joint' has been around for many years used in aeroplanes,cars,tractors and industry,an easy way to describe this is a ball with a hole in it possible an arm or bracket attached around the ball to allow movement/pivot action,a typical example is a car suspension,scootRS.com wrote:>>I'm not sure your definition of a Rose joint is the same as mine then.
Unlikely, given I'd never heard of a "rose joint" before recently
Sorry, half the time I don't know the technical terms in British English, and often not in any English, I know most of them in Vietnamese only which is what we speak at the shop.
Anyway, my point is that they aren't simply plain bolts otherwise you'd lock everything in place. They allow rotation. Rotatabolts? Boltators?
Cheers.
Dunno what a boltator is, but I do know what a rose joint is. Frank doesn't use rose joints, he uses a bronze bush at the axle and standard bolts with bronze bushes at both ends of the tie bar. The bolts are nipped up using a Binx nut to allow rotation.scootRS.com wrote:I'm going with "boltators".
I think Frank uses boltators as well, looking at that photo above.
Yes Joe, it is indeed a shouldered bolt. That's why I said it was in my post:joespeed wrote:could this be a 'shoulder bolt' or stepped bolt' ,the 'rose joint' has been around for many years used in aeroplanes,cars,tractors and industry,an easy way to describe this is a ball with a hole in it possible an arm or bracket attached around the ball to allow movement/pivot action,a typical example is a car suspension,
a picture may help identify its correct term.

i have not looked very close at this,does the caliper mounting plate pivot on the main axle spindle or is it as usual that is either with the plate onto the fork link spigot or bolted on to the fork link.if it is pivoted on the axle then there is no need to run disc links ever again,        a picture of a kit not attached to the scooter would verify this,        question is,does it work? i didn't see any racers with them on at cadwell!sideout wrote:Yes Joe, it is indeed a shouldered bolt. That's why I said it was in my post:joespeed wrote:could this be a 'shoulder bolt' or stepped bolt' ,the 'rose joint' has been around for many years used in aeroplanes,cars,tractors and industry,an easy way to describe this is a ball with a hole in it possible an arm or bracket attached around the ball to allow movement/pivot action,a typical example is a car suspension,        a picture may help identify its correct term.                 regards                  joe :lol:sideout wrote:...........

I don't really see the point of a twin disc kit. Only more complicated and more expensive. One disc is more than enough stopping power.mark wrote:have you ever considered a twin disc wheel ?
