Ok so managed to bend and grind drop outs enough to get Nexus 7 in and despite the abuse metered out the wheel is to all intents and purposes centred in the frame , that's a relief.
So was able to mock up parking brake and it looks as though it will work , just need to drill a hole and add control and cable.
A normal Flevo trike has 1 x elastomer and 1 x rod end bearing , these provide tilt and suspension
I have 2 x elastomer and 1 x rod end bearing , these 2 are used to kill the slew and to stiffen up the tilt department.
Question would it matter which orientation the elastomer's were in ?
So current I have 2 in tandem , however it would be easier to mount them side by side ?
Why you ask ? well it would then be a trivial task to swap them out too try different values ?
In tandem I have to remove the seat and split the 2 frames to get at the fixings ?
If they were side by side and I slotted the holes I could swap them out in under 5 minutes ?
Also the elastomer are rated on their load which is show as a vertical arrow and shear load which is show as a horizontal arrow.
However I am not using them in that manner , can I work out their resistance to bending from these figures ?
all for now Paul
