Diy Jackshaft Design Differencec
To some degree i agree with you.
However just because 2 things look alike dosen't mean they are even close.
Like the 2 chains. Diff. materials diff properties.
The components that make up the drive trains are standard.
In that it takes the combination of components the make the drive train.
That is like saying all bikes are the same.
There all bikes
They all have the same kind of parts.
But we know there not the same.
SO WHAT IS SO DIFF HERE????
#1 Sprag Clutch + adapter + any crank = Freewheel
(not the white industries freewheel)
SPRAG CLUTCH.
#2 JACKSHAFT / Bearing type / Shaft Type / Location / Gear Ratios
Haven't made it there yet but we are gonna do something about that high torque load on the freewheel. Which will reduce the torque throughout the whole system. BTW we won't affect the final output speed either.
Only tune it to where we want it to be.
#3 Plates
We will use high strength plate with Block type Bearing Mounts.
They will be similarly attached to the motor.
However the mounting to the seatpost will be changed.
We will aslo use stiffeners in between the plates.
#4 Fully published
PARTS LIST, CALCULATIONS, WORKING DRAWINGS, 3D MODELS INSTRUCTIONS, ECT.ECT.ECT
(with all that anyone including my grandma could get all the parts needed and also will be encouraged to make there own changes, after we complete this project anyone will be able to view this thread, and create there own bolt on kit.)
#4 looks
We will make it all look very pleasing. To our own taste.
#5 END Result
Anyone who makes an effort here can learn a **** of alot.
Anyone not interested in learning can use our work to get what they need.
The actual data can be used to compare shift system quality based on real info. Apples to apples. That is if you know what the other kit is made of.
AND OF COURSE ONE WONDERFUL SHIFT KIT BUILT TO LAST.
